Android java: behaviour state when configuration change (rotating mobile phone) Android N (7.0 / API 24)

After rotating mobilephone

1. onConfigurationChanged
2. onPause
3. onSaveInstanceState
4. onStop
5. onDestroy

Following

1. onStart
2. onRestoreInstanceState
3. onResume

NOTE: Important to keep state UI

• Save any state in onSaveInstanceState
• Restore InstanceState  in onRestoreInstanceState

To restore UI from InstanceState:

• restore in onResume
• if you use background service in OnStart, wait until it is finish. Easier way is UI handler -> handleMessage
