Description

generate aar with p4a, use the aar in the Kotlin app, and I can confirm the build apk contains the so file

can in kt like this

    override fun onStart() {
        super.onStart()
        val context=super.getContext()
        ServiceP4a_test_service.prepare(context)
        ServiceP4a_test_service.start(context,"aa")

    }

and I found aar extrac the so like this

public static void prepare(Context ctx) {
    String appRoot = PythonUtil.getAppRoot(ctx);
    Log.v("PythonService", "Ready to unpack");
    File app_root_file = new File(appRoot);
    PythonUtil.unpackAsset(ctx, "private", app_root_file, true);
    PythonUtil.unpackPyBundle(ctx, ctx.getApplicationInfo().nativeLibraryDir + "/libpybundle", app_root_file, false);
}

This is obviously a bug, everything is ok ,but can't load so file

Check if the "extractNativeLibs" option is enabled in your app's "AndroidManifest.xml":

    <application
        ...
        android:extractNativeLibs="true"
        ...>

I got the same "no such file" error if this is not enabled (the native libs directory would be empty). After enabling it in the app, the python bundle is loaded successfully.

Thx, it's resolved.
