Answer 1

Verify SYSTEM_ALERT_WINDOW Permission Or try to provide Overlay Permission Manually.

As @Fco P. said you can try to change

mRedBoxDialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);

**## If you are using Lenovo device. Please try with another one. This particular permission makes problem sometime in Lenovo device.****
