Superbird Custom Webapp

The spotify car thing runs it's software as a react web app in a QtWebView. This repo contains some small scripts to temporarily replace the webapp on a spotify car thing with a custom one. All actions not marked otherwise should be temporary, i.e. have no action and leave no trace after a reboot.

⚠️ Warning: Use at your own risk

Usage

Preparing your device

Before you can start using this repo, you need to prepare your device using superbird-bulkcmd. Perform all steps up to and including Boot kernel from USB to enable ADB access.

You need a working adb connection to your device.

Loading a custom build WebApp

Using scripts/load_webapp.sh, you can upload a custom webapp to your car thing.

./scripts/load_webapp.sh PATH_TO_YOUR_WEBAPP [DEVICE_ID]

This repo contains an minimal example, which you can start by running

./scripts/load_webapp.sh example_webapp/

If you have multiple adb devices, you can specify the device id of you car thing after the path to the webapp:

./scripts/load_webapp.sh example_webapp/ 123456

Loading a react based webapp

The react_webapp directory contains a small react-based demo app with some helper for properly using the car thing (buttons, "hey spotify", ...). To build and start it, run

./scripts/load_react_webapp.sh react_webapp

Restoring the old webapp

You can either just reboot your car thing or run scripts/restore.sh:

./scripts/restore.sh

Dumping the currently active webapp

For dumping the currently active webapp, you can simply use adb, no need for a custom script:

adb pull /usr/share/qt-superbird-app/webapp/ OUTPUT_PATH

Forwarding the websocket from the device

If you want to develop a part of your webapp which needs the control websocket, you can forward it to your computer:

adb forward tcp:8890 tcp:8890

This way you can develop the app on your computer without having to reupload it to your device all the time.

Internals

The script uploads the webapp to /tmp/webapp and bind-mounts it into the place the superbird binary expects it to be (/usr/share/qt-superbird-app/webapp/). It then restarts the superbird serivce using supervisorctl
