title: Android : Cardview Background is turning to black on 4.1.2
body: <p>I am using google cardView support library for my card functionality. It works well for kitkat and version up but however the background of card is set to black and padding/margins are not applied on device 4.1.2.</p>
  
  <pre><code>&lt;android.support.v7.widget.CardView
          android:id="@+id/all_goals_card_view"
          android:layout_height="wrap_content"
          android:layout_width="wrap_content"
          android:layout_marginRight="20dp"
          android:layout_marginLeft="20dp"
          android:layout_gravity="center"
          android:layout_marginTop="20dp"
          android:layout_marginBottom="20dp"
          android:padding="10dp"
          app:cardCornerRadius="4dp"
          card_view:cardPreventCornerOverlap="false"
          card_view:cardBackgroundColor="@android:color/white"
          &gt;
   &lt;/android.support.v7.widget.CardView&gt;
  </code></pre>
