I have a bluetooth devices which support A2DP\AVRCP but my mobile dosen't support AVRCP so i cant send metadata but Google Play Music sends metadata to that device how?

Tested Physical Device : Google Pixel XL,Samsung Galaxy Amp Prime.

Wile testing i got logs of Google Play Music which run this service bta2dp_codec_info_callback need more detail on that....

I already tried the code snippet mentioned in the link

Reference : send track informations via A2DP/AVRCP

  • see [A2dpNativeInterface.java](https://android.googlesource.com/platform/packages/apps/Bluetooth/+/refs/heads/master/src/com/android/bluetooth/a2dp/A2dpNativeInterface.java)... while it reads `onCodecInfoUpdateCallback pSupportedCodecs:0`. – Martin Zeitler Apr 24 '19 at 06:03
