OBSERVAÇÃO:
-
O AVRCP 1.0 será compatível no início. Os comandos de passagem de AVRCP precisam ser processados internamente pelo uinput.
-
O caminho de dados da A2DP precisa ser processado por um tubo de soquete entre a biblioteca android_audio_hw do AudioFlinger e a pilha Bluetooth.Representa a interface BT-AV padrão. Usado para as interfaces de origem e coletor do A2DP.
