Release app crash FATAL EXCEPTION: create_react_context (React Native)

I can build in debug mode, it works fine, but when I get release build, it gets build, but the application breaks, you can see the error output here.
FATAL EXCEPTION: create_react_context
java.lang.RuntimeException: Unable to load script. Make sure you're either running a Metro server (run 'react-native start') or that your bundle 'index.android.bundle' is packaged correctly for release.

running python in android app with chaquopy yields fatal error

I'm try to run python code in my android app using Chaquopy, I'm also using the moviepy library (I'm converting a mp4 file to a gif file). When I try to do the conversion I get the following error message:

I've found a fix for this problem (it involves changing the python code that would normally be generated by android studio, so any changes made to the python files will be overwritten during build time.
The python code is shown below
from moviepy.editor import VideoFileClip
def convert(path):
clip = VideoFileClip(path)
return clip.write_gif("output.gif", fps=24)
The java code used to start the pyhton code:
Python.start(new AndroidPlatform(getActivity()));
Python py = Python.getInstance();
PyObject gifConvert = py.getModule("gif_convert");
PyObject gif = gifConvert.callAttr("convert", file.getAbsolutePath());
Log.i("gif type", gif.toString());
Any help would be greatly appreciated.

Older versions of Chaquopy had a problem with pkgutil.iter_modules. This has been fixed in Chaquopy 6.2.1.

Nativescript Android build: Unable to instantiate activity ComponentInfo

I'm trying to create new Android app with Nativescript Angular, build passes ok, but when I try to run it on my device I get an error:
An uncaught Exception occurred on "main" thread.
java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{<my-app-id>/com.tns.NativeScriptActivity}: com.tns.NativeScriptException: Failed to create JavaScript extend wrapper for class 'com/tns/NativeScriptActivity'

Reproduction steps:
cd elipay-builds
tns create MyApp --appid <my-app-id> --template ng
cd MyApp
npm install --save-dev nativescript-dev-webpack
npm install
./node_modules/.bin/update-ns-webpack --configs --deps
tns run android
tns build android --bundle
UPDATE 1: I managed to figure out that an issue is somehow connected to the applicationId.
UPDATE 2: If I update id property in my nativescript's package.json file:
{
...
"nativescript": {
"id": "<my-new-app-id>"
},
...
}
I need to assign new applicationId to my app each time I build it. And this is wrong, since stores will recognize my app as different one after the update.
I don't know what else I can try. Please help me.
Thanks :)

How to build and use PJSIP for different architectures than armeabi?

I succesfully compiled PJSIP library for Android. Sample project works without any problems when I build for default architecture armeabi. Now I tried to compile library for arch such as armeabi-v7a and arm64-v8a. Unfortunately when I add libraries to project in appropriate folders (jnLibs/armeabi-v7a and jniLibs/arm64-v8a) application is not starting...
To setup build for different archs I use this command:
NDK_TOOLCHAIN_VERSION=4.9 TARGET_ABI=armeabi-v7a ./configure-android --use-ndk-cflags
I have this error on app launch:

Thanks for any help! :)

I was able to fix this error by updating the AndroidManifest.xml in "pjsip-apps/src/swig/java/android/app/src/main" to match my android target -- in my case to "23". Then "make clean" and another "make" in "pjsip-apps/src/swig", and rebuilding my app.
