title: Turning off Bluetooth when exiting an application
body: <p>As an introduction to my question, I'll tell you that I've searched around the correct way to do things but still didn't find an answer.</p>
  
  <p>I saw in many questions asked in stackoverflow, that exiting applications in Android is done simply by clicking the 'home' button. I saw some people say that it is not a common use to have an 'exit' button on your app.</p>
  
  <p>Here comes my question. Suppose I turn on the Bluetooth coonection in my app, so that two players can play one against each other with two phones/tablets. Now, they want to go out or they want to go on in their lives. How can I turn the Bluetooth off? is there a timeout for application that does this for me? Should I start a downtime counter to turn the Bluetooth off? What if the user decided to go out to read an SMS and then come back to the app, discovering the bluetooth is off?</p>
  
  <p>In other words, what is the correct manner to deal with shuting down Bluetooth when it is not needed any more with out interfering the user?</p>
  
  <p>Sorry for the long question, I just want to make myself clear.</p>
  
  <p>Thanks,
  AJ</p>
