Pixel devices as development platforms

This guide is mainly for developers who want to test and develop using AAOS

Caveats

These limitations apply when using a Pixel as development platforms:

The Pixel Tablet is verified and supported. You can visit Google Store to purchase it.
The following devices are supported but not actively tested. Be sure to download the correct binaries and then follow the instructions and change the commands as required:
- Pixel 5
- Pixel 6, 6a and 6Pro
- Pixel 7, 7a and 7Pro
- Pixel 8 and 8Pro
You must use Android 14 , build android-14.0.0_r30.
Limited support for Bluetooth profiles and some of the profiles will not work at all
Tablet does not support GPS, location requires "mock location app or similar"

Prerequisites

Before you continue, confirm you have the following items:

OEM unlocking is required.
Linux desktop capable of building Android code. For more information, see Establishing a Build Environment.

Code sync and build

To sync Android build AP1A.240405.002 :

mkdir aaos_on_pixel
cd aaos_on_pixel
REPO_ALLOW_SHALLOW=0 repo init -c -u https://android.googlesource.com/platform/manifest -b android-14.0.0_r30 --use-superproject --partial-clone --partial-clone-exclude=platform/frameworks/base --clone-filter=blob:limit=10M 
repo sync -j32

Download the vendor image for pixel devices from developers.google.com for AP1A.240405.002

curl --output - https://dl.google.com/dl/android/aosp/google_devices-tangorpro-ap1a.240405.002-8d141153.tgz  | tar -xzvf -
tail -n +315 extract-google_devices-tangorpro.sh | tar -zxvf -

Take a patch

cd packages/services/Car
git fetch https://android.googlesource.com/platform/packages/services/Car refs/changes/83/3037383/2 && git cherry-pick FETCH_HEAD #fix the audio crash
cd -

Run the build. :

. build/envsetup.sh
lunch lunch aosp_tangorpro_car-ap1a-userdebug
m

Build the Automotive-related packages:

m android.hardware.automotive.vehicle@2.0-default-service android.hardware.automotive.audiocontrol-service.example

Set up the device to flash the build

If you haven't already done so, enable Developer options. Go to Settings > System > About Phone and then tap Build Number seven times.

When you've enabled Developer options:

Go to Settings > System > Developer options and enable USB debugging and OEM unlocking:

Flash the build

To place the device into fastboot mode and then unlock it:
```
adb reboot bootloader
fastboot flashing unlock
```
On the device, select Unlock the Bootloader. Doing so erases all data on the device!
To flash the build:
```
fastboot -w flashall
```

After the build start booting with animation:

To enable adb remount:

#Temporary disable the userdata checkpoint 
adb wait-for-device root; sleep 3; adb shell vdc checkpoint commitChanges; sleep 2 
#Enable remount
adb remount && sleep 2 && adb reboot && echo "rebooting the device" && adb wait-for-device root && sleep 5 && adb remount

To push the required Automotive-specific files to the device:
```
adb sync vendor && adb reboot
```
Wait for the device to start:

Tips

If you see screen brightness too low:

adb shell settings put system screen_brightness 255

Boot when charger is plugged in:

adb reboot bootloader 
fastboot oem off-mode-charge 1
fastboot reboot

Enable Mock location:

    adb unroot
    adb shell cmd location set-location-enabled true
    adb root
    adb shell appops set 0 android:mock_location allow
    adb shell cmd location providers add-test-provider gps
    adb shell cmd location providers set-test-provider-enabled gps true
    adb shell cmd location providers set-test-provider-location gps --location 37.090200,-95.712900
    #To verify
    adb shell dumpsys location | grep "last location"
