title: android ram free up/ garbage collection
body: <p>All,</p>
  
  <p>I would like to free up ram on my android for a data intensive operation and also be able to free up ram when the user wants to. The first thing I thought of doing was running system.gc(). However, that is not a guarantee that the garbage collector will work. Any suggestions on how to immediately and guarantee that ram is freed up when the code is called.? Also, how do the apps that free up ram when you click a widget accomplish this task?</p>
  
  <p>I guess a better way to phrase this is: How do I manually free up memory like the Android OS?</p>
  
  <p>Thx</p>
