Change Your Context To ActivityName.this

Because this BadToken Exception ,So In your case you are adding the Progress Dialog to Your Activity Screen but passing the wrong context.

It would be good if you had paste your code. By the error logs its problem with your context. You might be passing a different context for the activity you are displaying.

Would have been lot easier if you pasted your code... but still there can be 2 possible reasons. 1. Context of wrong Activity. 2. you said that you are launching by a handler, please check the handler is of same activity for which you are using context in order to launch the dialog.
