InflateException with FloatingActionButton from Official Design Library
com.android.support:appcompat-v7:21+ added support for tinting widgets on devices running pre android 5.1 (API Level 21). To make use of it make sure you extend or set the AppCompat Theme and use app:backgroundTint instead of android:backgroundTint.
Example:
<android.support.design.widget.FloatingActionButton xmlns:app="http://schemas.android.com/apk/res-auto" android:id="@+id/fab" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_margin="16dp" android:src="@drawable/icon" app:backgroundTint="@color/accent" app:borderWidth="0dp" />
Just replace
<android.support.design.widget.FloatingActionButton ......android:backgroundTint/>to
<android.support.design.widget.FloatingActionButton ......app:backgroundTint/>
If you're using a VectorDrawableCompat (Vector asset) you should use:
app:srcCompat="@drawable/x"instead of:
android:src="@drawable/x"
