Answer 1

Try using older gradle dependencies version in you build.gradle file. It helped me.

Use:

compile 'com.android.support:appcompat-v7:23.1.0'
compile 'com.android.support:design:23.1.0'

Don't use:

compile 'com.android.support:appcompat-v7:23.2.0'
compile 'com.android.support:design:23.2.0'

I find solution here - Android Studio FloatingActionButton error

Answer 2

I think this happens when you run the app from eclipse while you already have the previous version installed ? This won't happen if you uninstall the app before running it again from eclipse. Also, this won't cause any problems.
