MonoDroid: About Bitmap.Recycle() and Bitmap.Dispose()

Question

Do I still need to call Bitmap.Dispose() after Bitmap.Recycle()? Or just Bitmap.Dispose() is enough?

Answer 1

According to Android documentation Bitmap.Recycle() should be enough:

Free the native object associated with this bitmap, and clear the reference to the pixel data.

Mono for Android documentation says exactly the same.

Also, this question gets a little further on how Bitmap.Recycle works.

Answer 2

Another solution could be to wrap in a using statement:

using (var bm = new Bitmap(..))
{
    // Do stuff with the Bitmap here
}

Just remember that when you leave the scope of the using statement, the Bitmap will probably be garbage collected. So if you are just drawing it to a Canvas or something this is a nice way to do it.
