Yes, I didn't think about that! That could definitely help me! But in this case:
1 - What would be the life cycle of this class singleton if the user sends the application (and so the activity that was displayed) in the background and the activity is destroyed for instance? 2 - How to make sure this singleton will stay alive as long as the secondary thread needs? 3 - I still don't really understand what happens when the secondary thread posts runnable toward the UI main thread that has been destroyed or sent to the background! Thanks a lot for your answer, It really helps me!
