I am guessing the window isn't shown as you've got hidden: true below. If the
window exists, instead of doing this you can probably just remove hidden: true
from the parameters.

Confirmed that the window isn't focused due to the 'hidden' attribute. I've
updated the comment.

+  var appWindow = chrome.app.window.get(appId);
+  if (appWindow) {
+    appWindow.focus();
+    return;
+  }
 
-  // TODO(kcarattini): Don't show the window until the launch mode has been
-  // established.
   chrome.app.window.create('main.html', {
     'frame': 'none',
     'resizable': false,
+    'hidden': true,
+    'id': appId,
     'bounds': {
       'width': 800,
       'height': 600
     }
   });
 });
