TFlite object detector app crashes just before making predictions

I tried several methods to deploy the tflite model on android, flutter, kotlin, etc, but andriod app keeps crashing when I want to make predictions. This was an error I got trying out the object detection codelab:

This issue was caused by android compressing the tflite model during the build. To solve this issue i had to instruct aapt not to compress the file.
go to build.gradle, at the app level, inside the andriod{} block, add
aaptOptions {
noCompress "model.tflite"
}
please rename model.tflite to your custom name if your tflite model is not named "model.tflite"

React Native app bundle crash. Unable to load script

I released my app BUNDLE on Google Play, and it crash at beginning. If I install manually the APK it runs correctly.
This is the error I got:

CLJSRN Release Build Runtime Failure

I inherited this CLJS React Native codebase and I'm trying to upgrade the Android SDK to v26 with React 16.4 and RN 0.56. The debug build works great but the release build fails when starting up with the following call stack:

Any ideas on how to get the non-minified version of the call stack? Is the minification done by the cljs to js compiler? Or the RN bundler/packager?
I'm currently using advanced optimizations on the cljs to js compiler. If I switch it to whitespace optimizations, then I get a build error
transform[stderr]: FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory
I can work around it by doing the bundling separately
node --expose-gc --max_old_space_size=4096 ./node_modules/react-native/local-cli/cli.js bundle --verbose --platform android --dev true --reset-cache --entry-file index.android.js --bundle-output /usr/src/app/android/app/build/intermediates/assets/release/index.android.bundle --assets-dest /usr/src/app/android/app/build/intermediates/res/merged/release
But I hit another failure
Unable to load script from assets 'index.android.bundle'.
Any ideas what else I can try?
Update 1: The "Unable to load script from assets 'index.android.bundle'." error message was caused by the index.android.bundle file being placed in the wrong folder. The following command worked:
node --expose-gc --max_old_space_size=4096 ./node_modules/react-native/local-cli/cli.js bundle --verbose --platform android --dev true --reset-cache --entry-file index.android.js --bundle-output /usr/src/app/android/app/src/main/assets/index.android.bundle --assets-dest /usr/src/app/android/app/src/main/res/
The unminified call stack looks like:

APK worked OK after I restarted the RN upgrade process with react-native-git-upgrade. There was another issue after the upgrade with some unresolved symbol during runtime but that turned out to be an issue with the externs file because I had switched from the deprecated BackAndroid to BackHandler.

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.
