title: how to provide Jelly bean support to android kitkat app
body: <p>I have made an android app, <code>minSdkVersion = 19</code> and <code>targetSdkVersion =19</code>.
  I have targetted it for devices having kitkat .Now i want to add Jelly Beans support to it . Right Now when i try to install my app on any jelly bean device it says:</p>
  
  <p><code>"No active compatible AVD's or devices found. Relaunch this configuration after connecting a device or starting an AVD."</code> </p>
