title: app keeps 'purging from font cache' and eventually crashes due to low memory, android
body: <p>I'm right at the beginning of building an app (which doesn't even do anything yet, but display some buttons) and when I run it, I get the error message in logcat:
  "purding 193K from font cache [23 entries]"
  over and over, until about a minute later the app crashes due to low memory.  My 3 buttons are custom buttons, using a custom font.  Problem with the font perhaps?</p>
