Someone created a plugin for torque to work on android auto

I would think it would work for other apps as well?
Same thing happen to me. If I connect my phone via Android Auto as soon as I start the car I get constant disconnects. The best solution I have found is to wait until the head unit connects to Ktuner before I connect my phone.
Or maybe someone can create a tuner viewer plugin for Android...
