Android: Android application is going for restart if we insert wireless USB mouse

I have one android application which has Main Activity.

If we insert wireless USB mouse - Activity restart lifecycle callbacks are getting triggered from android framework. (Like, onPause - onStop - onDestroy - onCreate - onStart - onResume).

But, If we insert wired USB mouse - Activity is not restarting.

How to prevent activity restart cycle on inserting wireless USB mouse,keyboard etc ??

Solution

  • Using wireless mouse causes activity to recreate. Adding navigation in configChanges solves the problem.

    <activity
  ...
  android:configChanges="orientation|screenSize|keyboard|keyboardHidden|navigation"
/>

    Now try to insert/remove Bluetooth mouse/keyboard etc. Activity wont recreate.
