AndroidAutoStub

• stock AndroidAutoStub extracted from pixel
• custom built Google Search App and Google Speech Services Stubs

Build (Generic AOSP)

This assumes you already are getting microg on your device some other way.

add this to your manifests to use:

<?xml version="1.0" encoding="UTF-8"?>
<manifest>
	  <project name="SolidHal/android-auto-stub" path="prebuilts/androidauto" remote="github" revision="master" />
</manifest>

then include the following line in your device.mk or common.mk:

PRODUCT_PACKAGES += AndroidAuto gappsstub speechservicestub

or you can also add it to your vendor/$vendor/config/common.mk

Now continue to "Get android auto setup" below

Build lineageOS with Android Auto

this method will include microg and Android Auto and the stubs automatically in your build

I suggest using https://github.com/lineageos4microg/docker-lineage-cicd

see the following repo for an example device: https://github.com/SolidHal/lineageos-microg-oneplus-lemonade

Now continue to "Get android auto setup" below

Get android auto setup

• Install the latest android auto apk (you can find this online or get it with aurora store)
• Install google maps in the same way
• open google maps once, grant it location permissions. Just while in use is fine.
• android auto should just work now

if you get stuck on google maps permission, try pressing cancel instead of settings.

if you are having trouble with first time setup, I found it was helpful to setup the bluetooth connection to the car before plugging in the usb c.
