I have a custom bluetooth wearable that essentially has two microphones, streams A2DP and handles AVRCP commands. I would like to connect this device to an Android phone and record audio either with AudioRecord or in native code. I need to do some signal processing on the data so I can't have it record directly to a file.
I have managed to build a version of Android using AOSP which will pair with the device and appears to receive the A2DP stream but I have not been able to build a version of the OS/SDK that allows me to use AudioRecord. I have gotten to the point where I can add a source for A2DP but I'm missing something at the native layer to fully make the connection.
Ideally, I would also like to control the input with AVRCP.
I am currently testing with a hammerhead device, but am will to move to another device if that works better.
Any input appreciated.
