BluetoothProfileManager.getInstance(); NoSuchMethod

[wangtianlang0912]

hi ,thanks for the demo ,recently I'm research a feature about how can use a a2dp sink on Android. so I download the androidthings and this demo project . But it's build smoothly while running crashed with "BluetoothProfileManager.getInstance(); NoSuchMethod", the androidthings is 0.6.1-devpreview android 8.1.0, a raspberry pi version. so I modify by Java reflection to get a BluetoothProfileManager Object, and it running well. then I use another android phone connect to it and play a song, the tone quality is very poor, of course I have try to remove the hdmi. I don't know why the tone quality is so poor, so I ask for a help, good wishes!
