Android QuickBlox视频调用扬声器不会自动打开

Question

我已经在Android，iOS和Web中实现了QuickBlox。但是，在Android中，当我们收到视频通话时，我将面临一个问题，然后手机的扬声器不会自动打开。我想在接收视频通话时自动使用扬声器。

我的音频经理示例代码： -

audioManager = AppRTCAudioManager.create(this);
    isVideoCall = QBRTCTypes.QBConferenceType.QB_CONFERENCE_TYPE_VIDEO.equals(currentSession.getConferenceType());
    if (isVideoCall) {
        audioManager.setDefaultAudioDevice(AppRTCAudioManager.AudioDevice.SPEAKER_PHONE);

        Log.d(TAG, "AppRTCAudioManager.AudioDevice.SPEAKER_PHONE");
    } else {
        audioManager.setDefaultAudioDevice(AppRTCAudioManager.AudioDevice.EARPIECE);
        audioManager.setManageSpeakerPhoneByProximity(SettingsUtil.isManageSpeakerPhoneByProximity(this));
        Log.d(TAG, "AppRTCAudioManager.AudioDevice.EARPIECE");
    }
    audioManager.setOnWiredHeadsetStateListener((plugged, hasMicrophone) -> {
        if (callStarted) {
            Toaster.shortToast("Headset " + (plugged ? "plugged" : "unplugged"));
        }
    });
    audioManager.setBluetoothAudioDeviceStateListener(connected -> {
        if (callStarted) {
            Toaster.shortToast("Bluetooth " + (connected ? "connected" : "disconnected"));
        }
    }); 

，当我尝试通过添加以下行来控制音频流管理器时，我的应用程序崩溃

   QBRTCAudioTrack localAudioTrack = currentSession.getMediaStreamManager().getLocalAudioTrack();
    localAudioTrack.setEnabled(true); // enable or disable audio stream

崩溃报告：

Answer 1

尝试以下代码

private AppRTCAudioManager audioManager;
audioManager = AppRTCAudioManager.create(this, new AppRTCAudioManager.OnAudioManagerStateListener() {
        @Override
        public void onAudioChangedState(AppRTCAudioManager.AudioDevice audioDevice) {
        }
    });

，而不是

audioManager.setDefaultAudioDevice(AppRTCAudioManager.AudioDevice.SPEAKER_PHONE);

Answer 2

使用以下代码：

private AppRTCAudioManager appRTCAudioManager;
appRTCAudioManager = AppRTCAudioManager.create(this);

if (currentSessionExist() && currentSession.getConferenceType() == QBRTCTypes.QBConferenceType.QB_CONFERENCE_TYPE_AUDIO) {
 appRTCAudioManager.selectAudioDevice(AppRTCAudioManager.AudioDevice.SPEAKER_PHONE);
}

和Onswitchaudio方法尝试以下方法：

 @Override
    public void onSwitchAudio() {      
       callService.switchAudio();
    }

public void switchAudio() {
        try {
            Log.v(TAG, "onSwitchAudio(), SelectedAudioDevice() = " + appRTCAudioManager.getSelectedAudioDevice());
            if (appRTCAudioManager.getSelectedAudioDevice() != AppRTCAudioManager.AudioDevice.SPEAKER_PHONE) {
                appRTCAudioManager.selectAudioDevice(AppRTCAudioManager.AudioDevice.SPEAKER_PHONE);
            } else {
                if (appRTCAudioManager.getAudioDevices().contains(AppRTCAudioManager.AudioDevice.BLUETOOTH)) {
                    appRTCAudioManager.selectAudioDevice(AppRTCAudioManager.AudioDevice.BLUETOOTH);
                } else if (appRTCAudioManager.getAudioDevices().contains(AppRTCAudioManager.AudioDevice.WIRED_HEADSET)) {
                    appRTCAudioManager.selectAudioDevice(AppRTCAudioManager.AudioDevice.WIRED_HEADSET);
                } else {
                    appRTCAudioManager.selectAudioDevice(AppRTCAudioManager.AudioDevice.EARPIECE);
                }
            }
        } catch (Exception e) {
            e.getMessage();
        }
    }
