Hi @taher.lakdawala, thanks for the post.

Are you able to reproduce this in the sample app? I’ve tried with 2 different Samsung devices (S21 Ultra and Tab S7) with Android 11 on the latest SDK version but have not seen any ANR dialogs or logs otherwise indicating something went wrong.

Thanks!

No not in sample app. We have integrated SDK with customized ui enabled in our app which is built in Qt cpp and for Java calls we are using JNI. The problem is if we want to call any API through JNI we have to change these to ui thread using runOnUiThread. And onDestroy even though it is in UI thread after leave meeting it is not getting killed. Is it something we are missing?

Hi @taher.lakdawala,

Thanks for confirming that it is not reproducible in the sample app.

I strongly doubt that this is an issue of the SDK being called from the wrong thread, since that would throw an exception instead of causing the app to hang.

At what point relative to the meeting’s state are you seeing the onDestroy callback of your Activity invoked?

Thanks!

When meeting state is MEETING_STATUS_INMEETING when app is getting killed from recent apps.
