Sorry you can only build with 29-30 so far with version 293.2+, but i review your issue not sure why it did work, but with latest framework (API 29-30) you must do
Attachment 30427
and this mode will work in any future framework, see that you are not using full mode you are using regular theme with action bar and status, without immersive mode.
so the first thing to do is to grant full mode immersive and hide status bar
