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:

There is a chance that you can brick your device, use it with caution!

• 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:

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

Code sync and build

1. 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

2. 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 -

3. 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 -

4. Run the build. :

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

5. 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:

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

Flash the build

1. To place the device into fastboot mode and then unlock it:

   adb reboot bootloader
   fastboot flashing unlock

2. On the device, select Unlock the Bootloader. Doing so erases all data on the device!
3. To flash the build:

   fastboot -w flashall

4. After the build start booting with animation:
   1. 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

   2. To push the required Automotive-specific files to the device:

      adb sync vendor && adb reboot

   3. Wait for the device to start:
      

      

   Tips

5. If you see screen brightness too low:

   adb shell settings put system screen_brightness 255

6. Boot when charger is plugged in:

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

7. 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"
