title: What happens to an Android thread after the Activity that created it is destroyed?
body: <p>In my Android app, the main Activity will sometimes start a Thread to load data from a server.  This thread modifies the app's database and edits some important files.  AFAIK, it would appear that this thread continues to execute.  What will happen to this thread if the Android gets into a low memory situation and decides to kill the entire Application?  Will there ever be a situation were this thread might die prematurely?  If so, is there any way I can see that the thread is being killed, and do something about it?</p>
  
  <p>I'm asking because this thread modifies important data in the database, and if it is suddenly killed, the application could stop functioning properly.</p>
