Question

I have app that connects to internet to get data. I can access data multi-level.

So let say I start at level 3 and on level 4 I decide to go back, whenever I press back the previous activity reloads the data from the internet.

Is there any possibility to prevent that?

I have tried to run the activity in single-top mode.

Answer 1

Move the data loading code to the single-exec event: onStart or

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    if(savedInstanceState == null) {
         // here
    }
}
