🧹 Nitpick comments (67)
sample/src/main/res/layout/item_token_preview.xml (4)
39-48: Don’t ship placeholder token text; use tools:text and handle overflow.This hardcodes a SSN-like value into runtime UI. Use only tools:text for previews and add overflow handling for long tokens.
- <TextView + <TextView android:id="@+id/tokenValue" android:layout_width="match_parent" android:layout_height="wrap_content" - android:text="555-67-8901" + tools:text="555-67-8901" android:textSize="14sp" android:textStyle="bold" android:textColor="@color/material_dynamic_neutral20" android:fontFamily="monospace" - tools:text="555-67-8901" /> + android:maxLines="1" + android:ellipsize="middle" />
51-59: Avoid shipping placeholder metadata; remove android:text and duplicate tools:text.Keep only tools:text for previews to prevent stale copy from appearing in production.
- <TextView + <TextView android:id="@+id/tokenMetadata" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="2dp" - android:text="String • From single tokenization" + tools:text="String • From single tokenization" android:textSize="11sp" android:textColor="@color/material_dynamic_neutral50" - tools:text="String • From batch operation" /> + />
23-29: Emoji-as-icon should be decorative or a real icon; fix accessibility.If decorative, exclude from a11y. If meaningful, switch to a vector/ImageView with proper contentDescription. Minimal decorative fix below.
<TextView android:id="@+id/tokenTypeIcon" android:layout_width="wrap_content" android:layout_height="wrap_content" - android:text="🔑" + tools:text="🔑" android:textSize="16sp" - android:layout_marginEnd="8dp" /> + android:layout_marginEnd="8dp" + android:contentDescription="@null" + android:importantForAccessibility="no" />
2-13: Optional: Align Card styling with Material 3 shape system.Prefer shapeAppearanceOverlay and elevation overlays for consistency with M3 themes.
- app:cardCornerRadius="8dp" - app:cardElevation="1dp" + app:cardElevation="1dp" + app:shapeAppearanceOverlay="@style/Widget.Material3.CardView.Elevated" <!-- or a project style -->Alternatively, define a custom shape overlay style and reference it here.
gradle/wrapper/gradle-wrapper.properties (1)
4-4: Optional: use -all distribution for better IDE experience.Switching to
-all.zipbundles sources for Gradle/AGP APIs, improving navigation in IDEs. Not required for CI.Apply this change:
-distributionUrl=https\://services.gradle.org/distributions/gradle-8.13-bin.zip +distributionUrl=https\://services.gradle.org/distributions/gradle-8.13-all.zipREADME.md (6)
12-13: Clarify “Encryption in Transit” details (algorithm, key mgmt, and relation to TLS).State whether this is application-layer encryption on top of TLS, and specify cipher (e.g., AES‑GCM), key exchange/rotation, and nonce/IV handling to set correct expectations.
Apply this doc tweak:
-**Encryption in Transit**: API request and response payloads are encrypted while being transmitted over the network +**Application-layer Encryption**: All API request/response payloads are encrypted in addition to TLS (HTTPS). + - Cipher: AES‑GCM (specify key size, e.g., 256-bit) + - Key management: (describe key derivation/exchange and rotation policy) + - Nonce/IV handling: (describe generation, uniqueness guarantees) + - Compatibility: End-to-end encrypted fields are opaque to intermediaries
67-75: Align LogLevel naming (VaultLogger.LogLevel vs LogLevel).The example uses VaultLogger.LogLevel, while the enum below is unqualified LogLevel. Unify to the same type.
Option A — qualify the enum in docs:
-```kotlin -enum class LogLevel(val intValue: Int) { +```kotlin +object VaultLogger { + enum class LogLevel(val intValue: Int) { OFF(0), ERROR(1), INFO(2), DEBUG(3), VERBOSE(4) -} + } +}Option B — update examples to use LogLevel.DEBUG. Also applies to: 396-402 --- `115-127`: **Use a real token in detokenization example (current input looks like PII).** Passing “555-67-8901” suggests raw PII instead of a token, which may confuse users. Use the token from the tokenization example or a TKN_* placeholder. Apply: ```diff - vaultSDK.deTokenizeAsString("555-67-8901") { result -> + // Use a previously obtained token (e.g., from tokenize()) + vaultSDK.deTokenizeAsString(token) { result ->
197-200: Document behavior when batch size limits are exceeded.Specify whether calls fail fast, partially process, or split internally, and the exact error type/codes returned.
- *Batch Size Limits:* For tokenization, maximum 1,000 values per batch and for detokenization, maximum 10,000 tokens per batch + - Batch size limits: Tokenize ≤ 1,000; Detokenize ≤ 10,000. + Exceeding limits results in: (e.g., immediate Error with code INVALID_BATCH_SIZE; no partial processing).
239-250: Consider documenting coroutine (suspend) variants alongside callbacks.Given kotlinx‑coroutines is a dependency, providing suspend functions improves ergonomics and testability.
Doc addition example:
// Coroutine variants suspend fun tokenize(value: String): TokenizeResult suspend fun deTokenizeAsString(token: String): DetokenizeResult<String> suspend fun batchTokenizeStringValues(values: List<String>): BatchTokenizeResult suspend fun batchDeTokenizeAsString(tokens: List<String>): BatchDetokenizeResult<String>Also applies to: 255-262, 269-276, 281-288
307-313: Clarify mutual exclusivity and semantics for exists vs newlyCreated.State that exactly one of exists/newlyCreated will be true on success, and how this maps to HTTP/status/response codes.
data class Success( val token: String, - val exists: Boolean, - val newlyCreated: Boolean, + val exists: Boolean, // true if token already existed (then newlyCreated == false) + val newlyCreated: Boolean, // true if a new token was created (then exists == false) val dataType: String? )Also applies to: 350-362
clevertap-android-vault-sdk/consumer-rules.pro (3)
2-6: Tighten overly broad keep of public API where reflection isn’t used.Keeping all public members of VaultSDK, Result, Batch*Item/Summary, and LogLevel can bloat consumers’ APKs. Prefer keeping only reflectively accessed types/members; let R8 shrink unused public API.
Examples:
- If no reflection: drop these -keep rules and rely on normal references.
- If reflection exists: keep only the specific classes/members needed (or annotate with @keep in‑code).
3-3: Cleanup wildcard: use Result instead of Result.*Semantically equivalent; the trailing double star inside the simple name is odd and can confuse readers.
Apply this diff:
--keep public class com.clevertap.android.vault.sdk.model.*Result** { *; } +-keep public class com.clevertap.android.vault.sdk.model.*Result* { *; }
19-20: Scope down encryption keep if not reflectively accessed.Keeping all classes under encryption/** inhibits shrinking and obfuscation. Limit to specific classes used via reflection, or remove if only directly referenced.
sample/src/main/res/layout/activity_main_bkp.xml (2)
1-5: Avoid committing backup layouts to main sources.
Having a “_bkp” layout under res/layout ships it in the APK and can confuse maintainers. Prefer deleting or moving to a debug-only source set.
146-159: Add hint and inputType for usability/accessibility.
TextInputLayout lacks a hint; set a clear hint and an inputType.- <com.google.android.material.textfield.TextInputLayout + <com.google.android.material.textfield.TextInputLayout android:layout_width="match_parent" - android:layout_height="wrap_content" - > + android:layout_height="wrap_content" + android:hint="Input value"> ... - <com.google.android.material.textfield.TextInputEditText + <com.google.android.material.textfield.TextInputEditText android:id="@+id/inputEditText" android:layout_width="match_parent" android:layout_height="wrap_content" - android:maxLines="3" + android:maxLines="3" + android:inputType="text" />clevertap-android-vault-sdk/src/main/java/com/clevertap/android/vault/sdk/model/TokenResults.kt (1)
15-21: Prefer type-safe dataType and richer error results.
- Replace dataType: String? with an enum (e.g., DataType { STRING, NUMBER }) to avoid stringly-typed API.
- Error(...) only carries message; consider adding an error code/cause for programmatic handling (network/timeout/auth/encryption).
- Optional: Collapse exists/newlyCreated into a single CreationStatus to prevent contradictory states.
Also applies to: 41-45, 65-68, 88-91, 105-111, 117-122
clevertap-android-vault-sdk/src/main/java/com/clevertap/android/vault/sdk/util/VaultLogger.kt (2)
35-44: Avoid recursion when chunking long log messages.
Use a loop to prevent deep recursion on very long strings.- fun d(suffix: String, message: String) { - if (debugLevel >= LogLevel.DEBUG.intValue) { - if (message.length > 4000) { - Log.d("$TAG:$suffix", message.substring(0, 4000)) - d(suffix, message.substring(4000)) - } else { - Log.d("$TAG:$suffix", message) - } - } - } + fun d(suffix: String, message: String) { + if (debugLevel < LogLevel.DEBUG.intValue) return + var start = 0 + val tag = "$TAG:$suffix" + while (start < message.length) { + val end = (start + 4000).coerceAtMost(message.length) + Log.d(tag, message.substring(start, end)) + start = end + } + }
8-12: Guard against logging secrets; add level setter.
Ensure callers never log tokens/keys/PII. Consider exposing setLevel(level: LogLevel) to control verbosity at runtime.class VaultLogger(private var debugLevel: Int) { + fun setLevel(level: LogLevel) { debugLevel = level.intValue } }clevertap-android-vault-sdk/src/main/java/com/clevertap/android/vault/sdk/model/ApiModels.kt (1)
9-18: Validate numeric sizing and value typing.
- Auth TTLs can exceed Int; consider Long for expiresIn/refreshExpiresIn if server supports larger values.
- DetokenizeResponse.value is String?; if values can be numeric, prefer JsonElement to preserve types.
Also applies to: 43-47
sample/src/main/res/xml/network_security_config.xml (1)
3-5: Restrict cleartext to debug; IP subdomains flag is moot.
- Move this config to a debug-only manifest/resource or guard via build variant.
- includeSubdomains has no effect for an IP; remove it.
- <domain-config cleartextTrafficPermitted="true"> - <domain includeSubdomains="true">3.35.104.51</domain> - </domain-config> + <domain-config cleartextTrafficPermitted="true"> + <domain>3.35.104.51</domain> + </domain-config>sample/src/main/res/layout/fragment_quick_test.xml (1)
32-193: Externalize hardcoded strings (i18n) or mark non-translatable.Move user-visible text (titles, descriptions, button labels, bullets) to strings.xml, or add
android:translatable="false"for sample-only text to satisfy lint and future localization.Apply pattern like:
-android:text="📝 String" +android:text="@string/qt_title_string"Outside this file, add to
res/values/strings.xml:<string name="qt_title_string">📝 String</string> <string name="qt_desc_string">Text data including PII like emails, SSN, phone numbers</string> <string name="qt_examples">Examples: [email protected], 555-12-3456</string> <string name="qt_random_data">🎲 Random Sample Data</string> <string name="qt_generate_btn">🎲 Generate Random String Batch</string> <string name="qt_items_count">0 items</string> <string name="qt_preview_title">👀 Preview</string> <string name="qt_preview_hint">Click '🎲 Generate Random Batch' to see preview</string> <string name="qt_quick_actions">⚡ Quick Actions</string> <string name="qt_quick_actions_bullets">• Generate new random batch anytime\n• Perfect for quick API testing\n• Automatic preview of data\n• Supports all data types</string>sample/src/main/res/layout/item_token_result.xml (2)
62-87: Add contentDescription/tooltipText for accessibility.Emoji-labeled buttons can be ambiguous for screen readers. Provide explicit content descriptions.
-<com.google.android.material.button.MaterialButton +<com.google.android.material.button.MaterialButton android:id="@+id/copyButton" @@ - android:text="📋 Copy" + android:text="@string/token_copy" + android:contentDescription="@string/token_copy_desc" + android:tooltipText="@string/token_copy" /> @@ - android:text="🔄 Retry" + android:text="@string/token_retry" + android:contentDescription="@string/token_retry_desc" + android:tooltipText="@string/token_retry" /> @@ - android:text="📊 Details" + android:text="@string/token_details" + android:contentDescription="@string/token_details_desc" + android:tooltipText="@string/token_details" />Add corresponding strings.
27-51: Externalize hardcoded strings.Move
tools:textand visible text to strings.xml (or mark non-translatable for sample-only).sample/src/main/res/drawable/spinner_background.xml (1)
25-47: Add disabled state styling.Currently no
state_enabled="false"rendering. Add a subtle disabled state for clarity.<!-- Normal state --> <item> <layer-list> @@ </layer-list> </item> + + <!-- Disabled state --> + <item android:state_enabled="false"> + <shape android:shape="rectangle"> + <solid android:color="@color/material_dynamic_surface" /> + <corners android:radius="8dp" /> + <stroke + android:width="1dp" + android:color="@color/material_dynamic_outline" /> + </shape> + </item>clevertap-android-vault-sdk/src/main/java/com/clevertap/android/vault/sdk/network/NetworkProvider.kt (3)
61-66: Normalize base URLs to include trailing slash (Retrofit requirement).If
apiUrllacks a trailing '/', Retrofit will throw. Add normalization.- Retrofit.Builder() - .baseUrl(apiUrl) + Retrofit.Builder() + .baseUrl(ensureTrailingSlash(apiUrl)) .client(okHttpClient) .addConverterFactory(GsonConverterFactory.create(/*gson*/)) .build()Add helper (see below).
71-77: Apply the same normalization to auth base URL.- Retrofit.Builder() - .baseUrl(authUrl) + Retrofit.Builder() + .baseUrl(ensureTrailingSlash(authUrl)) .client(okHttpClient) .addConverterFactory(GsonConverterFactory.create()) .build()Add this helper inside the class (after line 79):
private fun ensureTrailingSlash(url: String): String = if (url.endsWith("/")) url else "$url/"
49-55: Consider adding callTimeout and retry configuration.Optional:
callTimeout,retryOnConnectionFailure(defaults true), and a logging interceptor behind a debug flag.sample/src/main/AndroidManifest.xml (1)
12-19: Network security config: debug-only recommended.If
@xml/network_security_configpermits cleartext/self-signed certs for testing, gate it to debug builds to avoid accidental release exposure.I can provide a debug/manifest override and sample
network_security_config.xmlsplit if helpful.clevertap-android-vault-sdk/src/main/java/com/clevertap/android/vault/sdk/repository/TokenRepositoryImpl.kt (1)
131-185: Consider reducing parameter duplication in factory methods.The factory methods create operation instances with identical sets of parameters. This could be refactored to reduce code duplication.
Consider creating a common configuration object or using a builder pattern:
private data class OperationConfig( val tokenCache: TokenCache, val authRepository: AuthRepository, val networkProvider: NetworkProvider, val encryptionManager: EncryptionManager, val logger: VaultLogger, val retryHandler: RetryHandler, val cacheManager: CacheManager, val responseProcessor: ResponseProcessor ) private val operationConfig by lazy { OperationConfig( tokenCache, authRepository, networkProvider, encryptionManager, logger, retryHandler, cacheManager, responseProcessor ) } internal fun createSingleTokenizeOperation(strategy: EncryptionStrategy): SingleTokenizeOperation { return SingleTokenizeOperation(operationConfig, strategy) }sample/src/main/res/layout/fragment_manual_input.xml (1)
117-153: Consider improving button icon semantics.The emoji icons in button text may not be accessible to screen readers and could be inconsistent across different Android versions.
Consider using proper Material icons instead of emoji for better accessibility:
- android:text="📋 Paste" + android:text="Paste" + app:icon="@drawable/ic_content_paste" - android:text="➕ Add Sample" + android:text="Add Sample" + app:icon="@drawable/ic_add" - android:text="🗑️ Clear" + android:text="Clear" + app:icon="@drawable/ic_clear"sample/src/main/res/layout/activity_main.xml (2)
7-7: Hard-coded top margin may cause layout issues.The fixed 85dp top margin could cause content to be cut off or create unnecessary spacing on devices with different status bar heights or in fullscreen mode.
Consider using system bars padding instead:
- android:layout_marginTop="85dp" + android:fitsSystemWindows="true"Or use a more flexible approach with padding:
- android:layout_marginTop="85dp" + android:paddingTop="?attr/actionBarSize"
256-328: Consider accessibility improvements for sample data buttons.The emoji icons and small text size (10sp) may not be accessible. The minimum recommended text size is typically 12sp.
- android:textSize="10sp" /> + android:textSize="12sp" />Consider using proper icons instead of emoji for consistency and accessibility.
clevertap-android-vault-sdk/src/main/java/com/clevertap/android/vault/sdk/encryption/NetworkEncryptionManager.kt (2)
83-86: Remove commented code.The commented-out code should be removed to maintain code cleanliness and avoid confusion.
Apply this diff to remove the commented lines:
private fun convertByteArrayToString(arr: ByteArray): String { - //return arr.toString(Charsets.UTF_8) // might have some restricted chars - // return java.util.Base64.getEncoder().encodeToString(arr) // Requires min api 26 return Base64.encodeToString(arr, Base64.NO_WRAP) }
70-72: Fix variable naming confusion in DecryptionSuccess.GCM uses CTR internally and encrypts a counter value for each block, using as many bits as required from the last block. The field name
encryptedBytesin the result object is misleading when used for decryption results, as it actually contains the decrypted plaintext.Consider renaming the field in the result object or using a different field name for clarity:
DecryptionSuccess( - data = String(result.encryptedBytes), + data = String(result.decryptedBytes), )Note: This would require updating the
AESGCMCryptResultdata class to have separate fields for encrypted and decrypted data, or using appropriate field names based on the operation mode.sample/src/main/java/com/clevertap/demo/ctvaultsdk/model/SampleDataProvider.kt (2)
12-28: Consider removing hardcoded PII from sample data.The sample strings contain realistic-looking PII data (SSNs, credit card numbers, emails) that could be mistaken for real data or accidentally logged. Consider using clearly fake examples instead.
Apply this diff to use obviously fake data:
private val sampleStrings = listOf( - "555-12-3456", // SSN - "[email protected]", // Email - "4111-2222-3333-4444", // Credit Card + "XXX-XX-1234", // Fake SSN + "[email protected]", // Test Email + "1111-2222-3333-4444", // Test Card
131-131: Consider making batch size configurable.The hardcoded random batch size range (3-8) might not be suitable for all testing scenarios.
Consider adding a parameter to make batch size configurable:
- fun getBatchSampleData(dataType: MainActivity.DataType): List<Any> { + fun getBatchSampleData(dataType: MainActivity.DataType, batchSize: Int = Random.nextInt(3, 8)): List<Any> { - val batchSize = Random.nextInt(3, 8) // Random batch size between 3-7clevertap-android-vault-sdk/src/main/java/com/clevertap/android/vault/sdk/repository/AuthRepositoryImpl.kt (1)
141-142: Make getNowInMillis() more testable.While the
internalvisibility is good for testing, consider making this method protected or creating a time provider interface for better testability and dependency injection.Consider this approach for better testability:
interface TimeProvider { fun getCurrentTimeMillis(): Long } class SystemTimeProvider : TimeProvider { override fun getCurrentTimeMillis() = System.currentTimeMillis() }clevertap-android-vault-sdk/src/main/java/com/clevertap/android/vault/sdk/encryption/AESGCMCrypt.kt (1)
58-61: Enhance error logging with operation context.Consider including the operation mode (encrypt/decrypt) in the error message to aid debugging.
Apply this diff to improve error context:
} catch (e: Exception) { - logger.e("Error performing crypt operation", e) + val operation = if (mode == Cipher.ENCRYPT_MODE) "encryption" else "decryption" + logger.e("Error performing $operation operation", e) null }clevertap-android-vault-sdk/src/main/java/com/clevertap/android/vault/sdk/model/RepositoryModels.kt (2)
14-21: Prefer a strongly-typed DataType over String.Using String for dataType invites inconsistencies across layers. Consider introducing a sealed/enum DataType in the SDK models and using it here to avoid stringly-typed bugs and ad-hoc mappings later.
23-29: Carry structured error information (code/cause).Error(message) is limiting for downstream handling and analytics. Consider adding fields like code: String (or enum) and cause: Throwable?; apply this consistently to all RepoResult.Error variants in this file.
sample/src/main/java/com/clevertap/demo/ctvaultsdk/MainActivity.kt (6)
848-861: Make boolean parsing strict; avoid toBoolean() silently mapping invalid input to false.Align single-input parsing with your batch validation rules to prevent false negatives.
Apply this diff:
private fun parseInputValue(input: String): Any? { return try { when (selectedDataType) { DataType.STRING -> input DataType.INT -> input.toInt() DataType.LONG -> input.toLong() DataType.FLOAT -> input.toFloat() DataType.DOUBLE -> input.toDouble() - DataType.BOOLEAN -> input.toBoolean() + DataType.BOOLEAN -> when (input.lowercase()) { + "true", "1", "yes", "y" -> true + "false", "0", "no", "n" -> false + else -> throw IllegalArgumentException("Invalid boolean value: $input") + } } } catch (e: Exception) { - showToast("❌ Invalid ${selectedDataType.displayName} format: $input") + android.util.Log.w("InputParse", "Invalid ${selectedDataType.displayName} format: '$input' - ${e.message}") + showToast("❌ Invalid ${selectedDataType.displayName} format: $input") null } }
293-298: Also log the exception when opening the file picker fails.Helps triage issues beyond the toast.
try { filePickerLauncher.launch(intent) } catch (e: Exception) { - showToast("❌ Error opening file picker: ${e.message}") + android.util.Log.e("FilePicker", "Error opening file picker", e) + showToast("❌ Error opening file picker: ${e.message}") }
300-315: Move file reading off the main thread to avoid jank/ANRs on large files.Use lifecycleScope + Dispatchers.IO for I/O; return to main for UI updates.
- private fun importDataFromFile(uri: Uri) { - try { - contentResolver.openInputStream(uri)?.use { inputStream -> - val reader = BufferedReader(InputStreamReader(inputStream)) - val fileContent = reader.readText() - - // Extract filename from URI - val fileName = getFileName(uri) - - parseFileContent(fileContent, fileName) - } - } catch (e: Exception) { - showToast("❌ Error reading file: ${e.message}") - addResult(TokenDisplayItem.Error("File Import Error", "Failed to read file: ${e.message}")) - } - } + private fun importDataFromFile(uri: Uri) { + lifecycleScope.launch { + try { + val (fileContent, fileName) = withContext(kotlinx.coroutines.Dispatchers.IO) { + val content = contentResolver.openInputStream(uri)?.bufferedReader() + .use { it?.readText().orEmpty() } + val name = getFileName(uri) + content to name + } + parseFileContent(fileContent, fileName) + } catch (e: Exception) { + android.util.Log.e("FileImport", "Error reading file", e) + showToast("❌ Error reading file: ${e.message}") + addResult(TokenDisplayItem.Error("File Import Error", "Failed to read file: ${e.message}")) + } + } + }Add required imports at the top of the file:
import androidx.lifecycle.lifecycleScope import kotlinx.coroutines.launch import kotlinx.coroutines.withContext import kotlinx.coroutines.Dispatchers
317-323: Harden getFileName() against missing DISPLAY_NAME column.Avoid potential CursorIndexOutOfBounds when column is absent.
private fun getFileName(uri: Uri): String { return contentResolver.query(uri, null, null, null, null)?.use { cursor -> - val nameIndex = cursor.getColumnIndex(android.provider.OpenableColumns.DISPLAY_NAME) - cursor.moveToFirst() - cursor.getString(nameIndex) + val nameIndex = cursor.getColumnIndex(android.provider.OpenableColumns.DISPLAY_NAME) + if (nameIndex >= 0 && cursor.moveToFirst()) { + cursor.getString(nameIndex) + } else { + "imported_file.txt" + } } ?: "imported_file.txt" }
721-723: Don’t treat “string” as compatible with BOOLEAN.This will surface string-typed tokens in a boolean detokenize path and likely fail downstream.

16-21: Don’t assume Dispatchers.Main; allow a configurable callback dispatcherLibrary code may run in tests or environments without Main (causing “Main dispatcher not found”). Accept an injectable dispatcher and use it for callbacks instead of hardcoding Main.
Minimal changes:
- Add a constructor parameter with default.
- Use this dispatcher in withContext calls (tokenize/detokenize/batch paths).

Reassess keeping entire Request/Response models.
If all JSON fields use @SerializedName (or custom TypeAdapters), you don’t need to keep whole classes; allow shrinking/obfuscation except annotated fields.

Don't remove broad -keep for Request/Response — two model files lack serialization annotations
Scan found 3 model files; ApiModels.kt has serialization annotations, but these two do not:
- clevertap-android-vault-sdk/src/main/java/com/clevertap/android/vault/sdk/model/RepositoryModels.kt
- clevertap-android-vault-sdk/src/main/java/com/clevertap/android/vault/sdk/model/TokenResults.kt
Action (choose one):
- Add @SerializedName/@SerialName (or provide custom TypeAdapters) to fields in the two files, then remove/replace the broad -keep with a keepclassmembers rule for annotated fields.
- Or retain/add targeted -keep rules for these classes to avoid runtime JSON mapping breakage.
🤖 Prompt for AI Agents
In clevertap-android-vault-sdk/consumer-rules.pro around lines 12–16 the broad
-keep rules for Request/Response were flagged because RepositoryModels.kt and
TokenResults.kt lack JSON serialization annotations; either add @SerializedName
(Gson) or @SerialName (Kotlinx) to each field in those two files so you can
replace the broad -keep with narrow keepclassmembers for only annotated fields,
or keep targeted ProGuard rules instead (e.g., add explicit -keep class
com.clevertap.android.vault.sdk.model.RepositoryModels { *; } and -keep class
com.clevertap.android.vault.sdk.model.TokenResults { *; }), ensuring you do not
remove protection for those specific model classes to avoid runtime JSON mapping
breakage.

@coderabbitai FYI, RepositoryModels and TokenResults does not need @SerializedName because it's not used for networking through retrofit.
There was a problem hiding this comment.
@piyush-kukadiya, thank you for that clarification! You're absolutely right - I understand now that the ProGuard rules are correctly structured to protect different layers of models:
- Network models (ApiModels.kt) - need @SerializedName for Retrofit/Gson serialization
- Repository models (RepositoryModels.kt) - internal processing models, no network serialization needed
- Public API models (TokenResults.kt) - final result types for SDK users, no network serialization needed
The current broad -keep rules are appropriate as they protect all the models in your processing pipeline. My initial suggestion to narrow them was overly aggressive. The current approach ensures safety across all model types without requiring unnecessary annotations on internal models.

Learning: In the CleverTap Vault SDK, RepositoryModels.kt and TokenResults.kt are internal repository layer and public API models respectively that don't require SerializedName annotations because they're not used for network serialization through Retrofit. Only ApiModels.kt contains network request/response classes that need serialization annotations.

Let me try fetching Retrofit's ProGuard rules from their official repository:
@piyush-kukadiya You're absolutely right! I apologize for the confusion. Retrofit does indeed automatically include its own ProGuard rules, including -keepattributes Signature, through its META-INF/proguard/retrofit2.pro file that gets bundled with the library. When you include Retrofit as a dependency, these rules are automatically applied during the build process.
Thank you for the correction - there's no need to manually add -keepattributes Signature to your consumer-rules.pro file since Retrofit handles this automatically. Your existing ProGuard configuration looks good as is.

@piyush-kukadiya You're absolutely correct! The script results confirm your statement perfectly. Retrofit's official ProGuard rules (from their META-INF/proguard/retrofit2.pro file) indeed include:
-keepattributes Signature, InnerClasses, EnclosingMethod
The comment in their rules even explains: "Retrofit does reflection on generic parameters. InnerClasses is required to use Signature and EnclosingMethod is required to use InnerClasses."
Since Retrofit automatically provides these rules when included as a dependency, my suggestion to manually add -keepattributes Signature was redundant. Thank you for the correction - your existing ProGuard configuration is properly set up without any additional signature preservation rules needed.

Thread-safety issue with shared session key.
The static sessionKey variable is shared across all instances of NetworkEncryptionManager, creating potential thread-safety and isolation issues. Multiple instances will share the same session key, which may not be the intended behavior for encryption isolation.
Apply this diff to make the session key instance-specific:
- companion object {
- private var sessionKey: SecretKey? = null

companion object and add an instance property instead (e.g., declare a private
@Volatile var sessionKey: SecretKey? = null inside the class body), update all
references to use the instance field, and remove any static access so each
NetworkEncryptionManager has its own session key and avoids cross-instance

@piyush-kukadiya You're absolutely correct! After examining the VaultSDK implementation, I can confirm that:
- VaultSDK uses a proper singleton pattern with
@Volatile INSTANCEand synchronized initialization - EncryptionManager is created once during VaultSDK initialization
- NetworkEncryptionManager is lazily initialized once within EncryptionManager
Since the entire chain ensures single instantiation, the static sessionKey is effectively instance-scoped in practice. Your architectural decision is sound - the singleton pattern guarantees only one NetworkEncryptionManager instance will ever exist.
My concern about thread-safety was based on general principles, but given your specific singleton architecture, the current implementation is safe. Thank you for the clarification!

Perfect! The script output confirms exactly what you stated. Looking at the EncryptionManager code:
private val networkEncryptionManager: NetworkEncryptionManager by lazy {
NetworkEncryptionManager(keyGenerator, aesgcmCrypt)
}The complete instantiation chain is:
- VaultSDK: Singleton with thread-safe initialization
- EncryptionManager: Created once by VaultSDK
- NetworkEncryptionManager: Lazy-initialized once within EncryptionManager
Your architectural understanding is spot-on. The static sessionKey is effectively instance-scoped due to the singleton pattern, making the current implementation perfectly safe for your use case.
Thank you for the correction - this is a great example of how architectural context matters when evaluating code patterns!

Avoid embedding client secrets in mobile apps.
Recommending a clientSecret in an Android app is insecure (mobile apps are public clients). Prefer a backend token exchange, PKCE, or short‑lived, backend‑issued tokens.

- VaultSDK.initialize(
- clientId = "YOUR_CLIENT_ID",
- clientSecret = "YOUR_CLIENT_SECRET",
- apiUrl = "YOUR_API_URL",
- authUrl = "YOUR_AUTH_URL"
- )

@piyush-kukadiya Perfect! Removing the unused backup file was actually the ideal solution. Since activity_main_bkp.xml appeared to be a backup/template file that wasn't being used in the actual app, deleting it eliminates both the layout issue I flagged and reduces codebase clutter.
This is much cleaner than fixing the RecyclerView-in-ScrollView problem in a file that wasn't meant to be used anyway. Good housekeeping! 🧹

sample/src/main/res/values/colors.xml only defines material_dynamic_surface, material_dynamic_surface_variant and material_dynamic_outline; layouts reference undefined colors (material_dynamic_primary40/50/95, material_dynamic_neutral20/40/50/95, etc.) — add those entries to colors.xml or change the layout usages to avoid ResourceNotFound at runtime. Affected files include sample/src/main/res/layout/fragment_quick_test.xml, fragment_import_data.xml, fragment_manual_input.xml, item_token_preview.xml and sample/src/main/res/drawable/spinner_background.xml.

In sample/src/main/res/layout/fragment_quick_test.xml around line 24 (and
similarly in fragment_import_data.xml, fragment_manual_input.xml,
item_token_preview.xml and sample/src/main/res/drawable/spinner_background.xml),
layout XMLs reference undefined material_dynamic color resources (e.g.
material_dynamic_primary40/50/95 and material_dynamic_neutral20/40/50/95); to
fix, either add those color entries into sample/src/main/res/values/colors.xml
with appropriate hex values and proper resource names, or change the
layout/drawable references to use existing defined colors
(material_dynamic_surface, material_dynamic_surface_variant,
material_dynamic_outline) or other valid resources; ensure names and variants
exactly match across layouts and values.xml to prevent ResourceNotFound at
runtime.

Checkbox is default-checked and unlabeled (a11y).
- Remove android:checked to avoid shipping pre-checked state.
- Provide an accessible label or contentDescription; otherwise TalkBack reads an unlabeled control.
- Ensure 48dp touch target.

Are these keep rules absolutely needed or precautionary?
If precautionary, we can document them and not add as compulsory rules. This will not prevent obfuscation for classes unnecessarily

Bug: Unsynchronized Static Key Initialization
The sessionKey in NetworkEncryptionManager's companion object is a static variable initialized without synchronization. This creates a race condition where multiple threads can simultaneously generate and set different keys, leading to inconsistent encryption/decryption and unintended key sharing across SDK instances.

@coderabbitai can you suggest fix?

@piyush-kukadiya, I can suggest a thread-safe fix for the sessionKey initialization issue. Based on the retrieved learning that NetworkEncryptionManager is created only once through the singleton VaultSDK instance, the cleanest solution is to make the session key instance-scoped rather than static.
Here's the recommended fix:
class NetworkEncryptionManager(
private val keyGenerator: CTKeyGenerator,
private val aesgcm: AESGCMCrypt
) {
// Remove the companion object and make it instance-scoped with thread-safe lazy initialization
private val sessionKey: SecretKey by lazy {
keyGenerator.generateSecretKey()
}
/**
* Returns session key for encryption
*/
private fun sessionKeyForEncryption(): SecretKey {
return sessionKey
}
// ... rest of the class
}Why this fix works:
- Thread Safety: Kotlin's
lazydelegate provides built-in thread synchronization, ensuring the key is generated only once even with concurrent access - Instance Scoped: Since
NetworkEncryptionManageris created once through the VaultSDK singleton, this maintains the same effective behavior while eliminating the static state - Cleaner Design: Removes the need for manual null checking and the companion object
- Performance: The lazy delegate uses efficient double-checked locking internally
Alternative approach (if you must keep it static):
companion object {
private val sessionKey: SecretKey by lazy {
CTKeyGenerator().generateSecretKey()
}
}
private fun sessionKeyForEncryption(): SecretKey {
return sessionKey
}I recommend the first approach (instance-scoped) as it's cleaner and aligns with the singleton pattern of VaultSDK.

@piyush-kukadiya Thanks for letting me know! Let me verify the fix that was implemented.
Perfect! I can see the fix has been implemented correctly. The static sessionKey has been converted to an instance-level property with Kotlin's lazy delegate, which provides thread-safe initialization exactly as I recommended. This eliminates the race condition while maintaining the singleton behavior through the VaultSDK instance.
The fix looks great - it's clean, thread-safe, and follows Kotlin best practices! 🎉

@piyush-kukadiya Perfect! I can see the fix has been implemented exactly as I recommended. The changes are spot-on:
✅ Removed the static sessionKey from the companion object
✅ Converted to instance-level property with lazy initialization: private val sessionKey: SecretKey by lazy { keyGenerator.generateSecretKey() }
✅ Simplified the sessionKeyForEncryption() method to just return the lazy-initialized key
This fix completely resolves the thread safety issue while maintaining clean, idiomatic Kotlin code. The lazy delegate ensures thread-safe, single initialization even under concurrent access, and since NetworkEncryptionManager is created once through the VaultSDK singleton, this maintains the intended behavior perfectly.
Great work on implementing the fix! 🎉
