使用

SppManager.connectBluetoothA2DP(device, new IBtConnectCallBack() {
                                @Override
                                public void onSucces() {
                                    closeDialog();
                                }

                                @Override
                                public void onFail() {
                                    closeDialog();
                                }
                            });
