Error inflating class android.support.design.widget.FloatingActionButton
Because android:backgroundTint
doesn't work below android API 21, so you need to use app:backgroundTint
instead.
Use
app:backgroundTint
in stead of
android:backgroundTint
Hope it will work.
Tried your code, the problem is with the 23.4.0 library.
Upgrade to 24.+ , there's no error in that lib.
For example :
implementation 'com.android.support:appcompat-v7:24.2.1' // appcompat library
implementation 'com.android.support:design:24.2.1'
You need to change the compile version to 24 too.
compileSdkVersion 24
