Question

I made an app that is just a simple counter that will keep track of a user’s strokes as they play golf and save their score while doing it. I simply want the app to not be killed when the user exits out. I just want it to run in the background. So the user can re-enter the program after doing other things, (like texting or checking email)

I understand I need to use services but while trying to research the topic on the web and in other forums, it seems that they all explain how to have a specific activity in the app to continue, not the entire app.

How might I do this?

Answer 1

You could do something like this

  @Override
  protected void onPause()
  {
    super.onPause();

    SharedPreferences settings = getSharedPreferences("YourOwnPickedName", 0);
    SharedPreferences.Editor editor = settings.edit();
    editor.putString("score", the_users_score);
  }

and get the score back by doing

  @Override
  protected void onResume()
  {
    super.onResume();
    SharedPreferences settings = getSharedPreferences("YourOwnPickedName", 0);
    the_users_score = settings.getString("score", "0");
  }
