How to Reproduce

Environment:

  • Flutter 3.29.1
  • AirBridge SDK (airbridge_flutter_sdk: 4.4.1)
  • AppLovin SDK 4.3.1 (from pubspec.lock)
  • Android devices only
  • Multiple ad mediation SDKs integrated (AppLovin, Google Ads, AdPopcorn, etc.)

Reproduction Status:
❌ Not reproducible in development/testing environment

Steps Attempted:

  1. Install app version with AirBridge SDK integration
  2. Launch app on various Android devices
  3. Navigate through all app screens/features
  4. Perform normal user actions (ads loading, in-app purchases, etc.)
  5. Leave app running in background/foreground
  6. Test with different network conditions

Result: No crashes reproduced during manual testing

Production Environment Specifics:

  • Crashes occur only in production (Google Play Console/Firebase)
  • Issue appears intermittent and device-specific
  • Likely related to specific device configurations, timing, or user patterns not covered in testing

Relevant Dependencies:

# Key SDK versions that may interact with AirBridge
applovin_max: 4.3.1

// Android native dependencies
implementation 'com.applovin:applovin-sdk:13.0.1'
implementation 'com.google.android.gms:play-services-ads:23.6.0'
implementation 'io.channel:plugin-android:12.1.0'
// + multiple ad mediation adapters

### Reproducible in the demo app?

Not Tested

### Additional Info

**Additional Context:**

This issue has been causing significant problems for 2 weeks. The crash occurs simply by adding and initializing the AirBridge SDK - no other code changes were made.

**Technical Details from Android Vitals:**
- Crash logs show `XmlBlock$Parser.getAttributeNamespace` being called
- Unable to identify which specific XML file or component is being parsed when the crash occurs
- This makes debugging extremely difficult as the root cause XML resource is unknown

**Questions:**
1. Can simply adding and using AirBridge SDK cause conflicts without any additional implementation?
2. Is there a way to identify which XML file/component triggers the `XmlBlock$Parser.getAttributeNamespace` call?

**Impact:**
- Production app stability severely affected
- Issue persists across multiple Android devices
- No workaround found after extensive investigation

**Request for Help:**
Any guidance on identifying the specific XML resource or component causing this parser issue would be extremely valuable for debugging this crash.
