That looks fine. The only issue/trick for bitmaps that I'm aware of is
the option to call bitmap.recycle(), which forces the bitmap to free
its pixel memory immediately, rather than waiting for the GC. This is
optional, since the GC will trigger this too. Calling recycle() is
tricky, because now the bitmap object is "dead", and will throw an
exception if it is used, so only do this if you're low on memory, and
want to free some up right away (and you're SURE you won't reference
that bitmap again).

I’ve seen many discussions on freeing Bitmaps, but I don’t think I
have ever seen a definitive answer on the proper method of doing it.
I have an activity which creates a custom class, and the custom class
has a clear method, which I call before freeing the class.
Below is the code from my custom class, and, and following it is the
code from the OnDestroy event . Is this sufficient to make sure I am
not leaking memory? Note that it is untested code right now, so may
contain a few spelling mistakes.
public class JSONDataTable
{
public ArrayList<Bitmap> BitmapArray;
…..
Methods etc.
……
public void Clear()
{
if (BitmapArray != null)
{
for (int i = BitmapArray.size() - 1; i > -1 ; i-- )
{
BitmapArray.set(i, null);
BitmapArray.remove(i);
}
}
BitmapArray = null;
}
}
FROM THE ACTIVITY
protected void onDestroy()
{
if (JSONProductTable != null) {
JSONProductTable.Clear();
JSONProductTable = null;
}
}
Sincerely,
