title: Android - How to use ORMLite dbhelper for whole app lifecycle
body: <p>I'd like to use ORMLite, but I don't like I have manage 1 database helper for each activity. Wouldn't be better to have one for whole app lifecycle? Until now I've used greendao and it has not this issue.</p>
  
  <p>I wanted to implement it, however I can't find any suitable way to release db helper properly when destroying app (I can easily open it in Application's onCreate), because there is no Application's onDestroy() method.</p>
  
  <p>Does anyone have some way to do it?</p>
