In every instance in all of my classes where I reference R.id.something, the R is in red and it says "cannot resolve symbol R".
And when I run 'app', it shows all the 'textColor' in styles.xml getting an error.

@Alexander : Main reason is R.java not generating .
Open the Android SDK Manager and Update with latest:
- Android SDK Tools
- Android SDK Build Tools
Then Clean with Re-Build and Restart Your Project
And
Android Studio marks R in red with error message "cannot resolve symbol R", but build succeeds
Try this way ,I hope it will helps you .

Problem of appcompat.. untill your res folder contains error. R.java will not be generated.
