Could Not Find Class 'android.graphics.drawable.RippleDrawable' Android Studio 2.2.3

Could not find class 'android.graphics.drawable.RippleDrawable', referenced from method android.support.v7.widget.AppCompatImageHelper.hasOverlappingRendering

Solution 1:

check your themes config. all themes must have a parent from AppCompat.

like this:

<style name="AppTheme.NoActionBar" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
    <item name="android:actionMenuTextColor">@android:color/white</item>
</style>

if you not specify the parent, the appcompat lib would have no effect.
