Build Error: Nullable, NotNull, Support.Annotation, and StringDef

Steps to reproduce

1. Follow the installation steps (including proguard rules, etc)
2. Attempt to run ./gradlew bundleRelease

Expected behaviour

Application builds on android.

Actual behaviour

Android build errors out on ./gradlew bundleRelease. 18 errors during compile, cannot find symbol @NonNull, @Nullable, @StringDef, due to package android.support.annotation supposedly not existing. We are using Jetifier, and I have tried the solutions recommended in #221 but have had no success.

Build errors below:

Execution failed for task ':react-native-twilio-video-webrtc:compileReleaseJavaWithJavac'.
> Compilation failed; see the compiler error output for details.

After trying many things to solve the error I found one that worked for me, it is not ideal but if it can help someone : Directly in the modules, in react-native-twilio-video-webrtc/android/src replace all imports android.support.annotation. by androidx.annotation.

It makes it compatible with androidx (Usually the job of jetifier but not this time)

I have also added implementation 'com.android.support:support-annotations:+' in my dependencies app build grade but I’m not sure if it helps (I won’t remove it because it works and I don’t want to break everything)

EDIT : I’ve just seen that PR #433 does exactly this

using @marqroldan trick by calling npx jetify in the root folder did the trick for me
