title: Nativescript android remove action bar
body: <p>I am trying to develop android app using Nativescript and try to remove Action Bar (top bar with "testns" title), but don't know how.
  I am using code below but not working. Currently using tns v.1.3.0</p>
  
  <p><code>
      var frameModule = require("ui/frame");
      exports.pageLoaded = function(){
          var topmost = frameModule.topmost();
          topmost.android.showActionBar = false;
      };</code></p>
