CarAPP Overlay
This is a tool that automatically creates an overlay for the CarAPP on the QF001 (ROCO K706) Head Unit.
Usage
1. Preparation
You must have JRE and JDK installed, link below:
JDK: https://www.oracle.com/java/technologies/downloads/#jdk20-windows
JRE: https://www.java.com/en/download/
2. Download
On the top right corner of this GitHub page, click on the green Code button and then click Download ZIP. Then extract that anywhere.
3. Modifying text & translations
If you want to change the strings in the default, English language, open the default-resources/res/values/strings.xml and find a string you want to translate.
Copy it, and paste it into resources/res/values/strings.xml.
Then you can change its value.
If you want to change strings in another language, repeat the same process, but first you have to make a folder for the appropriate language in the resources/res folder.
If you were to, for example, modify the Croatian translation, you'd put your strings.xml inside resources/res/values-hr/strings.xml.
4. Modifying images
If you want to modify images, find them in the default-resources/res/drawable* folders, create the appropriate folder in the resources/res/ folder, and put your new image there.
5. Compilation & installation
Click on compile.bat and it will automatically compile and sign an overlay APK for you.
After that you can install it by running installer.bat and following the instructions.
Hints:
- make sure USB debugging is turned on on your head unit, if you're unsure, do the following:
- car settings -> factory -> enter "114477"
- enter Android settings, go to the About page
- tap the build number 7 times
- developer options will now be available on the About page, open them
- turn USB debugging on
- make sure the PC on which you're running the
install.batscript and the headunit are on the same network - my suggestion is to just turn on a hotspot on your phone, and connect both the PC and the head unit to it - then you can also easily find the IP in the "connected devices" in phone hotspot settings
