AMBridge

A bridge between Apple Music and Zeekr's automotive OS. (not even a prototype)

Current state

Third party developers are not able to get a binder to CoreService (like hvac, mediacenter, etc).

You need to give this app permission to fetch notifications in order for playback info to work (artist, title, album, artwork)

What's implemented

• Playback control
• Media info display (need permission to get notifications)

Caveats

1. Use Log.e because Zeekr OS only shows error level in production vehicles.
2. ecarx openapi has several caller verification:
   1. Package name got SHA1-ed and compared with the appKey in your metadata, appSign in license.txt
   2. You need to have an encrypted license.txt in your assets
   3. The public key used to decrypt license.txt can be found in CoreService.apk (extract it from your vehicle)
   4. Your package name and app uid also got verified. (getPackageName() must in getPackagesForUid)
   5. The decrypted license.txt looks like this:
