Verify app installation

To verify if the process of installing an app "as Google Play Store" went correctly, check as following:

Settings => Apps => See all apps => Name of installed App => Store (at the bottom)
There you should see either of following, App installed from ... messages:
- Google Play Store - On devices with Google Play Store enabled
- FakeStore - On devices with MicroG (Google Play Store stub)
- license checker - On AVDs without Google Play

Notes

Make sure to enable Unknown Sources in Android Auto's Developer Settings.

King Installer only installs .apks "as Google Play Store".
So it overcomes only 1 of multiple restrictions put into place by Google.

You might still need to patch your phenotype.db with AA-Tweaker for the apps to show up in Android Auto.

If you're on MicroG, then you likely are still missing the actual phenotype.db + a .pb file,
see this fork of aa4mg for that.

Video - Example usage

Restriction applies only to Android 11 and above.

It works in 8 out of 10 cases.
If it didn't work for you, here's a video for you about an alternative variant.

Android Auto still won't show some apps.

Some apps have additional restrictions applied on them by AA,
which leads to them still not showing up, even if "installed as Google Play Store".

To unlock these apps use the Xposed module provided by Android Auto - XLauncher Unlocked

For this phone you need to reinstall\update the current Google PackageInstaller, you can download the same version from ApkMirror or similar site, or you can get the apk directly from your phone using a file manager with that feature (I'm use mixplorer) then install the apk as normal and now you can use kinginstaller to install the app and will work!
