title: Android game loop, how to control speed and frame rate
body: <p>I've written a game for Android, and I've tested it on the Dev Phone 1.  It works perfectly, the speed is just right.  However, I'm sure phone CPU's are getting faster.  They may already be faster than the dev phone.</p>
  
  <p>How do I make sure that my game runs at the exact same speed no matter what the device or how fast it runs?  Do you know of any techniques?  Should I check some kind of timer at the top of the loop each time?</p>
  
  <p>I guess I'm referring to frame rate - but mostly the speed at which my game runs through the main game loop.</p>
  
  <p>Any theory or experience would be great!  Thank you.</p>
