You should give more details, but to find the offending line, run the app in DEBUG LEGACY.

Does it happen every time you debug your app in rapid debug mode?

Only on lg phone. on my samsung tablet it doesn't

Try to switch to debug (legacy). It seems like some network problem that causes the rapid debugger to crash.
