[MOD] AppRadio Unchained - Full mirorring for Pioneer AppRadio

[MOD] AppRadio Unchained - Full mirorring for Pioneer AppRadio 
The Pioneer AppRadio is a radio with a 7" touch screen. Android devices can be connected via HDMI and shown on the screen.
Touches and keypresses are sent back to the Android device via Bluetooth. The radio has a GPS receiver and data is sent
over Bluetooth as well. In essence a very nice concept.


To connect to an AppRadio there's a Pioneer AppRadio app available in the Play store. The Pioneer AppRadio app
is however quite restrictive. It allows only to run a small number of apps that are approved by Pioneer. These approved
apps can interact with the AppRadio app because they have a built in Pioneer SDK. The number of useful apps is small.
For details look here: Pioneer Appradio Knows website.

The goal of this project is to modify the Pioneer AppRadio app in such a way that it allows full mirroring. 
This means that any app can be used and controlled using the touch screen and keys on the headunit. 
Also any application can receive GPS data from the AppRadio.

Current status of AppRadio Unchained Reloaded (has built in GPS Injector) (paid)
In addition to the AppRadio Unchained mod of the Pioneer AppRadio app, a completely Pioneer-less app was developed.
Basically it allows you to connect to your AppRadio in a faster and easier way without the need to use Tasker.
For details see here: AppRadio Unchained Reloaded

Current status of the ARUnchained GPS Injector (to be used with the AppRadio Unchained Mod) (paid)
GPS injection on system level using mock locations is available in the playstore here: ARUnchained GPS Injector
For GPS Injector details go to the FAQ here: ARU FAQ
Please fill out the survey here: ARUnchained GPS Injector survey
Navigation apps that already have AppRadio support like Waze and Navfree still work using the HU GPS. If you only use those apps then you don't need ARUnchained GPS Injector.
Head unit models that have built in navigation like AVIC-Z150BH, AVIC-F50BT and similar are not supported as Pioneer does not support sending of GPS data to the android device. If you are unsure, a test that can be done is to install Waze, if Waze can use the GPS of the head unit, ARUnchained GPS Injector works as well.
