title: Finish android activity via Cordova
body: <p>I'm currently working on an Android Application using Phonegap/Cordova.
  I need to finish the current activity and go back to the previously active activity/app.</p>
  
  <p>Is there an easy way to call the <code>finish()</code> method (of the Activity class) from my Javascript code using Cordova?</p>
  
  <p>Thanks in advance.</p>
