Error inflating class android.support.design.widget.FloatingActionButton

Question

My app crashed because

Error inflating class android.support.design.widget.FloatingActionButton

This is my code in the XML

<android.support.design.widget.FloatingActionButton         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_gravity="bottom|right"         android:layout_margin="16dp"         android:src="@drawable/icon_right"         app:backgroundTint="@color/green"         android:onClick="previewphoto"         app:layout_anchorGravity="bottom|right|end" /> 

and here is my gradle

compile 'com.android.support:appcompat-v7:23.4.0' // appcompat library compile 'com.android.support:design:23.4.0' 

my logcat

Can somebody tell my fault?

Answer 1

Use

app:backgroundTint 

in stead of

android:backgroundTint 

Hope it will work.
