Kano - It has been a while since I've checked here. I have been looking back in the code for the android app and noticed that the endpoint for seeing the JSON data is formatted as JSON data but the the content type is returning as text/html.
I know changing it to "application/json" may break existing apps including my own, but since I'm back and mining on the pool again and noticed this, I thought I would let you know.

I plan on making an update for the android app to handle both in the case that this situation is updated, otherwise it will continue to function the same. I figure it is time to give it a face lift and more options, time permitting of course.
The following:
Content-Type:text/html; charset=UTF-8
Should read:
Content-Type:application/json; charset=UTF-8
