Hi,

  I think you are refering A2DP Sink role. Currently it is not supported by the bluedroid stack which is provided by Broadcom as a part of stock Android. You need to have your own implementation to have your device as A2DP Sink.

  Also I would like to hear from you for which use case you want to set your device to sink?

Regards,

It’s interesting why a mobile device should serve as the A2DP sink. Please share us the use cases as well.

Nonetheless, it should be possible to make your custom A2DP sink with your own implementation (jitter handling with RTP, decode via SBC/MP3 et al).

 

Good luck.

 

Regards,

Jayanta

I am curious too, but one likely case may be in car infotainment industries, where Android tablets may be employed and expected to serve as A2DP sink for equally enabled phones – just a thought.

I am looking for something like this because I have an android tablet in my car and I would like to play music from my android smartphone and make and receive phone calls via bluetooth.

Hello,

According to developer.android.com website (BluetoothA2dp class overview): Android only supports one connected Bluetooth A2dp device at a time. 
So, it is not possible to stream the same content to more than one A2DP capable device (headset). I don't know if this is a BT protocol specifications limitation or a BT protocol stack implementation limitation. I know that this was not possible in BlueZ and it is not possible in BlueDroid.
