title: Activity's public void onLowMemory() method does not called by android framework when system runs OutOfMenory
body: <p>I create bitmap drawables from large images and OutOfMemory error occures at that time. 
  Activity.onLowMemory() method should be called but actually it is not called by framework.</p>
  
  <p>Is there any solution of this, or is there any other way to capture OutOfMemory error in android?</p>
