1. I managed to stop the crashing by providing a Handler() in the callbacks of Camera2 where it was null.

2. Also moving to legacy mode still crashes on this device. So, I bypassed that by commenting the code in method chooseCameraIdByFacing().

3. And sometimes camera doesn't takes picture. Like when clicking quickly multiple times. The log in this case is below

convertRequestMetadata - control.awbRegions setting is not supported, ignoring value
W/LegacyRequestMapper: Only received metering rectangles with weight 0.
W/LegacyRequestMapper: Only received metering rectangles with weight 0.

This code has been a lot help to me. Hope this helps!
