This is a Magisk module that adds AA (Android Auto) to de-googled devices running microG on Android 13!
Tested under LineageOS 20 only, but should run on all Android 13 devices. (See here for other Android versions)

Warning

Before uninstalling aa4mg,
Settings => Apps => See all apps => Android Auto => Triple dot icon (top right corner) => Uninstall updates

Otherwise you may end up with an un-boot-able device.
If the AA system app is missing (by disabling aa4mg or booting without Magisk),
but the AA update installed is still present,
your device may fail to boot due to permission errors!

Installation

Install LineageOS for microG
Install Magisk
Install the dependencies for AA, choose one of either options for each dependency:
- As empty / stub APKs:
  Install the APKs included in the stubs folder of this repo,
  use King Installer to "install as Google Play Store".
- As full / official APKs:
  Install through Aurora Store,
  use Root installer as installation method to "install as Google Play Store".
- Feel free to freeze these dependencies through Hail.
Install Android Auto through Aurora Store,
use Root installer as installation method to "install as Google Play Store".
Install the aa4mg module through the Magisk Manager App => Reboot
Settings => Connected Devices => Connection Preferences => Android Auto
- Scroll down => Tap Version 10 times => Accept PopUp to become a developer
- Triple dot icon (top right corner) => Developer Settings

  - Scroll down => Check Unknown Resources

Updates

Once the installation is complete, Android Auto can be updated through Aurora Store.

First steps

When first using your device in your car,
follow the usual flow on your head unit and device until you reach a page asking for location permissions for maps.
Double check maps has permissions and click "cancel".

If nothing happens, unplug and re-plug your device.
When asked for, grant all permissions.

In case you encounter an error "Communication error 17",
manually open Settings and grant all available permissions to the Android Auto app.
Then unplug and re-plug your device.

3th party apps

Android Auto won't show apps not installed through Google Play Store.
To mitigate this, first un-install the app, then you can use following ways to "install as Google Play Store".

Play Store APKs: Use Aurora Store + Root installer as the installation method, works for single + split APKs.
Non Play Store APKs: Use King Installer, works for single APK.
Or use direct ADB install, works for single APK:
```
pm install -i "com.android.vending" <apk>
```

Can not open Android Auto

If you can not directly open the AA app after installation,
then you can still access the AA settings through either of below ways:

Settings => Connected Devices => Connection Preferences => Android Auto
Install the Android Auto for phone screens .apk included in the stubs folder of this repo,
use King Installer to "install as Google Play Store", then launch AA through this app.
