The catch? I have forked the repo, made a couple very small changes (like small changes to timeouts for example), and created a build with Jitpack. I checked their Jitpack build log (https://jitpack.io/com/github/polidea/RxAndroidBle/release-1.12.1-rxjava2/build.log) against my own, and they are almost identical. I see the missing errors, I have the exact same ones. The difference is that if I use the official polidea rxAndroidBle gradle thing (which I believe is pulled from Jitpack), I do not get the same runtime issue.
I have been looking for hours and feel like I am at a dead-end. I wanted to create an issue against the repo, but I am not confident that it is their issue. Something specific with what I have done with the build, but I do not know where the difference could be.

I was able to solve the issue by adding again the missing libraries that are not resolved when publishing a version with JitPack.

I am not able to figure out the error please help me.
Thanks

Your release configuration in build.gradle is not correct for your libraries. I think it have to do with json, and proguard obfuscates some methods of it.

React Native app crashing at startup on Android: Didn't find class "com.facebook.react.devsupport.DevSupportManagerImpl"

I am using React Native v 0.62.2 and I am trying to get my project running on Android as well. Up until now, I had focussed development on iOS and therefore did never run the Android app. Now I wanted to run the android app but the app crashes on startup right after the splash screen was shown with the following stacktrace:

I searched the web for solutions or at least hints but did unfortunately not find any solution or even any idea of what could be done to fix this issue.
Does anyone have any idea? Also please let me know if you need any further information in order to be able to answer the question.
Thanks a lot!

For all who are struggling with this issue as well - after a long period of research plus try and error, I got it finally fixed.
It seems that this issue actually is correlated to OK HTTP. The steps that made me get it running were the following:
Enable MultiDex but also keep attention on going for the AndroidX solution (as I use the latest version of React Native which already leverages AndroidX) as stated in the following answer:
https://stackoverflow.com/a/56875424/9055450
Follow the instructions given in the following comment adding ProGuard files: https://github.com/facebook/react-native/issues/9043#issuecomment-298832659

The issue seems to be related to libdeepspeech-jni.so not being included when Android Studio is used. I am completely new to Android development (I'm building a Mozilla-STT React Native module and only supporting iOS is useless) so this is especially confusing.
Thanks!
EDIT:
Hours of random trial and error later: Changing this option from "Default APK" to "APK from app bundle" in Android Studio made the demo start working
However, doing the same on my example app for the React Native module (which has a dependency android project which finally depends on the actual libdeepspeech) didn't work. It started working when using x86_64, so there must be no libdeepspeech x86 binary.
