[mythtv] Android lockup when showing the new gallery's settings

[Paul Harrison]

While testing the Android build on FireTV 4k I came across a couple of
lockups/problems. The first is when trying to open the settings pages
for the new Image gallery. Doesn't look like they have been converted
over to the new settings yet so are still using the old Qt settings
pages. The only way out seems to be to press Home to close the FE.


The second is whenever the web browser is shown the area for the web
browser is blank unless you press something to like menu.


So basically anything that causes a new window to be shown above the FE
one will cause problems.
