Question

I had a method that makes me a continuous loop with postAtTime every x seconds using (Handler), except that this method is placed in an activity A, when going into the activity B and then return to A for pressing stop button for finsih loop, I can not stop it with mHandler.removeCallbacks (..) I am attaching here the method

Button Start:

mHandler.postAtTime(mUpdateTimeTask, 100);

Loop:

private  Runnable mUpdateTimeTask = new Runnable() {
     public void run() {
          Toast.makeText(getBaseContext(),"ok!",Toast.LENGTH_SHORT).show();
          mHandler.postDelayed(this, 1000);
      }
   };

Button Stop:

mHandler.removeCallbacks(mUpdateTimeTask);

Answer 1

// In your handler
SharedPreferences sp = context.getPreferences();
boolean loop = sp.getBoolean("should_loop_ad_infinatium", false);
if (loop) {
    Toast.makeText(context, "ok", Toast.LENGTH_SHORT).show();
    mHandler.postDelayed(this, 1000);
}

from another activity

SharedPreferences sp = context.getPreferences();
Editor e = sp.edit();
e.putBoolean("should_loop_ad_infinatium", false);
e.commit();
