Is there any way to detect the existence of the VOLUMN keys for android devices? Some features should be hidden if there no VOLUMN keys. Appreciate for any help^.^
For Volume Keys use KEYCODE_VOLUME_DOWN and KEYCODE_VOLUME_UP
@Override
public boolean onKeyLongPress(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_VOLUME_DOWN)
{
// to your stuff here
return true;
}
return super.onKeyLongPress(keyCode, event);
}
