Answer 1

getLastNonConfigurationInstance() returns an activity instance. You can fetch the previous value from that instance:

in your onCreate():

YourActivity prevActivity = (YourActivity) getLastNonConfigurationInstance();

if(prevActivity!= null) { 
      this.bTemp = prevActivity.bTemp;
   }

and your onRetainNonConfigurationInstance() method should be:

@Override
@Deprecated
public Object onRetainNonConfigurationInstance() {
    return bTemp;
}

and your 'onActivityResult()` method should be:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    bTemp = (Bitmap) data.getExtras().get("data");
    iv.setImageBitmap(bTemp);
}
