title: When does an Android Singleton get destroyed?
body: <p>Will a Singleton survive even if the activity is totally destroyed? I have some references to the Android Location Managers which call services to do GPS stuff, it works fine for an hour or two (Even with the app minimized and the screen is turned off) but after some time the updates will stop pinging, I have looked over some other Stack Overflow threads and I have seen conflicting responses about whether a Singleton will stay active or if it will be destroyed if the system needs memory. </p>
  
  <p>If a Singleton is not a good way to keep a reference for a long period of time, what is the alternative? </p>
