RemotiveLabs and Android Emulator

This is a set of Python scripts to redirect data from RemotiveCloud to AAOS emulator.

Example

Check the video in /media for an example on how location can be sent from RemotiveCloud to AAOS emulator.

Setup

It is highly recommended that you read the documentation in docs/build/html/index.html, as it describes the steps in more details. It can be tricky to make it work if you miss some configurations.

Make sure to install the dependencies.

pip install -r requirements.txt

Download the Android Studio Preview version: https://developer.android.com/studio/preview

Run

Create a free RemotiveCloud account and go to the Recordings page. Choose the City drive to Turning Torso recording and start the playback. Make sure to pick configuration_android when playing. Note! If you already have an account, you can import the City drive to Turning Torso recording by clicking the import icon in the upper right corner of the recording page.

Send Location

Run the AAOS Emulator. For sending location, you can use an user image such as:

  • Automotive 12L with Play Store ARM 64 v8a System Image
    • If your machine is ARM based. It is an user build with GAS.
  • Automotive 12L with Play Store Intel x86 Atom_64 System Image
    • If your machine is x86 based. It is an user build with GAS.

Include the credentials from the broker (URL and API key) as well as the LATITUDE and LONGITUDE signals:

$ python3 br_location_to_emu.py --url $URL --x_api_key $KEY --namespace android --signal LATITUDE --signal LONGITUDE

Note! You can find the broker credentials in the bottom left corner once you have prepared the recording for playback.

Set VHAL Properties

To manipulate VHAL properties, you must use an userdebug build:

  • Android Automotive 13 "Tiramisu" with Google APIs ARM 64 v8a System Image
    • It does not contain GAS, but it is userdebug.

Run the emulator via command line:

$ emulator @$avd_name -selinux permissive -no-snapshot

Note that you must set SELinux as permissive mode.

If you want to send VHAL property values to AAOS emulator:

$ python3 br_props_to_aaos.py --url $URL --x_api_key $KEY --namespace android --signal $SIGNAL

alternatively

$ PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python python3 br_props_to_aaos.py --url $URL --x_api_key $KEY --namespace android --signal $SIGNAL

Send the signals you want by always putting the flag --signal alongside its name.
