Android Studio FloatingActionButton error

Question

I installed Android Studio yesterday, and after battling multiple java and other errors, I have come to an error that I cannot seem to fix. I have not added anything or done

Answer 1

This worked for me:

I changed in the build.gradle file.

compile 'com.android.support:design:23.2.0'

to

compile 'com.android.support:design:23.1.0'

Then clean, rebuild, then "refresh" each layout file. The refresh button on the top right in the layout editor.
