[Android Studio Errors] Face Alarm App

Problem
Camera2Renderer had an error. I forget what it was since I already fixed it. But basically it had so many missing a variables that stemmed from there.
Solution
Change the project structure for the compile sdk version because they added hardware in a different version.

Problem
emulator: ERROR: x86 emulation currently requires hardware acceleration!
Please ensure Intel HAXM is properly installed and usable.
CPU acceleration status: HAXM must be updated (version 1.1.1 < 6.0.1).

Solution
??

Conclusion
I hate to leave errors unsolved, and I'm not sure if I'll continue this project. I hate to leave this project unfinished because of my anger issues with android development. I can say that I am leaving this project at a pause.
