 savedInstanceState=new Bundle();
 savedInstanceState.putBoolean("isLogoLoaded",true);
 }else{
 savedInstanceState.putBoolean("isLogoLoaded",true);
}  

please provide the better way thanks .

Answer 1

Which method are you calling that logic?

I am guessing that is in onCreate(), onCreate is where you LOAD the savedInstanceState, it is NOT where you SAVE your data. (you can also load it in onRestoreInstanceState)

You want to save your data in public void onSaveInstanceState(Bundle savedInstanceState) {

 @Override
 public void onSaveInstanceState(Bundle savedInstanceState) {
     super.onSaveInstanceState(savedInstanceState);
     savedInstanceState.putBoolean("isLogoLoaded", true);
 }
