Whilst porting this application example: https://github.com/rciovati/Android-KeyboardView-Example

I get the following crash when I click a "Key".

I/dalvikvm-heap( 3314): Grow heap (frag case) to 9.737MB for 625936-byte allocation

Which is coming from this code:

mKeyboardView.Key += (sender, e) => {
                long eventTime = JavaSystem.CurrentTimeMillis();
                KeyEvent ev = new KeyEvent(eventTime, eventTime, KeyEventActions.Down, e.PrimaryCode, 0, 0, 0, 0, KeyEventFlags.SoftKeyboard | KeyEventFlags.KeepTouchMode);
