title: My android app shows a video and must be always running, but after few hours my app is stopped
body: <p>I'm new on android application and i'm creating an app that shows a video using a VideoView, I use a CountDownTimer to search each 15 seconds for video updates and play another video. My app works very well during 2 or 3 hours but after this my app just stop, the application doesn't close but is stopped and I must close and open again. What should I do? Thanks.</p>
