title: Maintaining application state in Android
body: <p>I'm trying to guess why, if I open my application, lock the device and some hours later resume the activity it crashes. I suppose thats why, after some time, Android destroy my app and then tries to resume and im not saving correctly the state of my activities.</p>
  
  <p>How can I force Android to destroy my app as it does usually without having to wait hours?</p>
  
  <p>Thanks in advance</p>
