This is the exception you will get if you are performing any UI operation on any thread or from any background task. Also context.runOnUiThread won't work.

Instead use:

activity.runOnUiThread(new Runnable() {
                            @Override
                            public void run() {
                             mDialog.dismiss();
                            }
                          });

You can use the same for showing where activity is the object of activity.
