crash starts with this --> Attempt to load writable dex file: /data/user/0/com.xxxxx.xxxxxx/cache/app_resources_lib.jar

[welmas]

//extern
App *app;
//-----------------

extern "C" JNIEXPORT jstring JNICALL
Java_com_xxxxx_xxxxxxx_MainActivity_stringFromJNI( JNIEnv* env, jobject thiz) {

std::string hello = "Hello from C++";

app = ::firebase::App::Create(::firebase::AppOptions(), env, thiz);

return env->NewStringUTF(hello.c_str());

}

This looks like it's probably related to a change in more recent versions of Android that affects how we run dynamic code: https://developer.android.com/about/versions/14/behavior-changes-14#safer-dynamic-code-loading

We'll get working on a fix as suggested in that doc.

Thanks for bringing this to our attention!

This has been fixed in firebase/firebase-cpp-sdk#1430 and will be included in the next SDK release (11.5.0). Thanks for the bug report!
