• In your activity's class: Override 2 methods:
  
  
  
  • void onCreate(Bundle savedInstanceState);
  
  
  • void onPause();
  
  
  
  


• Then, modify your override methods to install your Save/Restore function:
  
  
  
  • Create some global variable
  
  
  • Save in onPause() method
  
  
  • Restore in onCreate() method
  
  
  
  

Modification override method
