title: How I can prevent installation of my android app in phones?
body: <p>I am developing a tablet app. How i can prevent installation of apk in phones. I added following lines in manifest. </p>
  
  <pre><code> &lt;uses-sdk
      android:minSdkVersion="14"
      android:targetSdkVersion="19" /&gt;
  
  &lt;supports-screens
      android:largeScreens="true"
      android:normalScreens="false"
      android:requiresSmallestWidthDp="600"
      android:smallScreens="false"
      android:xlargeScreens="true" /&gt;
  </code></pre>
  
  <p>But it can install on phones too. Is it will be ok, when the app is live?</p>
