As I mentioned earlier, many JVMs disable System.gc by default, since the function is so often abused, and since doing unnecessary GCs is a major performance drag. When inserting GC calls in your code you should be sensitive to this and use only the bare minimum necessary to achieve "correct' (in the Android sense) operation.
