title: Android CardView padding and minHeight
body: <p>Today I updated support dependencies in my project and I found some issues with the new <code>CardView</code>.</p>
  
  <p>Previous version:</p>
  
  <pre><code>compile 'com.android.support:cardview-v7:21.0.0-rc1@aar'
  </code></pre>
  
  <p>Current version:</p>
  
  <pre><code>compile 'com.android.support:cardview-v7:21.0.0@aar'
  </code></pre>
  
  <p>First of all it looks like <code>minHeight</code> doesn't work any more. One of the solutions is to put any <code>ViewGroup</code> inside the card and set the minimum height, but it looks like a bug for me.</p>
  
  <p>The second issue for me are paddings. With the new library release paddings are larger. If you put some cards next to each other the gap between them is way to large. I've tried setting the padding to <code>0dp</code> but it looks like the padding comes from <code>9.png</code> file. The code pasted below doesn't change anything.</p>
  
  <pre><code>&lt;android.support.v7.widget.CardView
      android:padding="0dp"
      ...
  </code></pre>
  
  <p>I've also tried with negative values but also nothing. Is there any way to solve this two issues for pre-Lollipop devices?</p>
