compile 'com.bandou:a2dp:VERSION'

compile 'org.greenrobot:eventbus:3.0.0'

====================================
基本方法说明
====================================
//判断A2DP是否连接
if (A2dpManager.getInstance().isConnect()) {
	//连接A2DP
	A2dpManager.getInstance().connect(macAddress);
}
else{
	//断开连接
	A2dpManager.getInstance().destroy();
}

====================================
在Activity或其它地方注册A2dpStatusEvent
EventBus.getDefault().register(this);
====================================

@Subscribe(threadMode = ThreadMode.MAIN)
public void onA2dpStatusEvent(A2dpStatusEvent event) {
    EventBus.getDefault().unregister(this);
    if (event.isSuccess()) {
        Toast.makeText(mContext, "连接a2dp成功", Toast.LENGTH_SHORT).show();
    }
    else{
        Toast.makeText(mContext, "连接a2dp失败", Toast.LENGTH_SHORT).show();
    }
}
