title: ?android:attr/selectableItemBackground` requires API level 11 (current min is 10)
body: <p>If I use this on my card view as <code>foreground</code>, application will crash on pre <em>API 10</em>.</p>
  <pre><code>    &lt;android.support.v7.widget.CardView
      android:id=&quot;@+id/card_view&quot;
      android:layout_width=&quot;match_parent&quot;
      android:layout_height=&quot;match_parent&quot;
      android:layout_gravity=&quot;center&quot;
      android:layout_margin=&quot;@dimen/card_margin&quot;
   //android:foreground=&quot;?android:attr/selectableItemBackground&quot;
      android:elevation=&quot;3dp&quot;
      card_view:cardCornerRadius=&quot;@dimen/card_album_radius&quot;&gt;
  </code></pre>
  <p>I'm working on a project about seven months and my app worked on every API level until now.. this is forcing me to raise my min SDK.</p>
  <p>Can you please help me with this, how can I bypass it.</p>

  <h1><strong>temporary answer</strong></h1>
  <p>I'm using this</p>
  <pre><code>android:foreground=&quot;?attr/selectableItemBackground&quot;
  </code></pre>
  <p>insteat of:</p>
  <pre><code>android:foreground=&quot;?android:attr/selectableItemBackground&quot;
  </code></pre>
  <p>It's some kind of gray color onClick instead of blue, but I do not care much about the color, So this will solve the crashing problem for now</p>
