Answer 1

I also encountered this error. For me, it was when changing the target SDK from 26 down to 25. I was able to fix the problem by changing the appcompat dependency version from

implementation 'com.android.support:appcompat-v7:26.1.0'

to

implementation 'com.android.support:appcompat-v7:25.4.0'

This will allow the compiler to access the styling attributes that it is currently unable to find. This will actually fix the problem instead of masking the real issue as Enzokie suggested.
