How to pause execution of back button until subscription completes?

I'm running into tons of problems using RxAndroidBle when events like back button press happen and I was wondering what the best way to pause execution of the back button is. I basically want to create a lock until a particular bluetooth operation completes. Once the operation completes I want to finish the execution of the back button. Anyone have any ideas?

Solution

  • Just override the back button and use some flag? E.g.

    private boolean delayedBack = false; // as member field

...other Activity code

@Override
public void onBackPressed(){
   if(someCondition)
      super.onBackPressed();
    else
      delayedBack = true;  
}

    Then when some asynchronous operation finishes just check that flag:

     if(delayedBack){
   super.onBackPressed();
   delayedBack = false; // in case you don't want to finish the Activity
  }

    Of course instead of using super.onBackPressed(); which in most cases will finish the Activity you can perform any other action you'd perform when the user hits the back button.
