How can I build the android library? #3692

While I'm able to run and build bootstrap.sh without problems, when I try to run tools/android-build or just gradle assemble inside the android directory I get dependency errors related to aarch64 linux (I'm building on mac):

$ …/tools/android-build

I do have the following built static libraries though:

$ find rust -iname '*.a'
rust/target/release/deps/libwallet_core_rs-40a43b0105a0b584.a
rust/target/release/deps/libwallet_core_rs-a06f0fc7efacfacb.a
rust/target/release/deps/libwallet_core_rs-3eab26e831b0940d.a
rust/target/release/libwallet_core_rs.a
rust/target/release/build/secp256k1-sys-b1932e21bed3b233/out/libsecp256k1.a

If I try to build inside the docker image I get Java erros:

root@b5d0268f0791:/wallet-core# ./tools/android-build 
/wallet-core/android /wallet-core

ERROR: JAVA_HOME is not set and no 'java' command could be found in your PATH.

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.

Do I need to set up a full linux virtual machine to build the android library or is it possible to do on mac?

Sure, forgot to add a few more lines:

./tools/install-wasm-dependencies
source ../emsdk/emsdk_env.sh
./tools/generate-files

Hi @chokokatana, could you please try to run ./tools/generate-files before running ./tools/android-build?
This should help

That script fails to run, missing some emcc program:

  --- stderr


  error occurred: Failed to find tool. Is `emcc` installed?


warning: build failed, waiting for other jobs to finish...

Maybe I need to run yet another script after bootstrap.sh?

Hi, @satoshiotomakan , After I run your few lines:

./tools/install-wasm-dependencies
source ../emsdk/emsdk_env.sh
./tools/generate-files

Then run:

./tools/android-build

Still got it wrong, it was:

C/C++: /Users/l1en/<path>/wallet-core/jni/cpp/Random.cpp:16:54: warning: unused parameter 'reserved' [-Wunused-parameter]
C/C++: JNIEXPORT jint JNICALL JNI_OnLoad(JavaVM *jvm, void *reserved) {

Its total output is a bit long, so I cut the part where the error occurred.

I really need your help. Thank you.

You don't have space on your machine:

A failure occurred while executing com.android.build.gradle.internal.tasks.MergeNativeLibsTask$MergeNativeLibsTaskWorkAction
No space left on device

Oh...., my bad, I didn't look closely at the error output.

Do you know how much storage space need? Because I really don't have space left.

Thanks.
