NO_INPUT_CHANNEL is a hidden WM flag that allows creation of a window without an input channel. Unfortunately in releases prior to Android R this would allow creation of a Window which will not be known to the InputDispatcher at all. This means that the logic generating FLAG_OBSCURED will work and a window will be able to overlay another window without the overlayed window being notified. In Android R and later this isn't a problem as the InputDispatcher is informed of all windows, input channel or not. For past Android releases, this patch disables NO_INPUT_CHANNEL for use outside of the WM. Bug: 152064592 Test: Existing tests pass Change-Id: I7e1f45cba139eab92e7df88d1e052baba0ae2cc6
