audio - Openvidu - 将视频通话音频设置为扬声器 Android

Question

我按照 android 教程项目在我的应用程序中实现 openvidu，但是当我开始通话时，声音从听筒（如通话期间）而不是扬声器中发出。我可以修复它吗？

Answer 1

你可以这样做：

//Import audio manager
import android.media.AudioManager;

public class MyVideoCallActivity extends AppCompatActivity {

    private AudioManager audioManager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        //.....SOME CODE

        //Start Video call method
        startVideoCall();
    }

    public void startVideoCall() {
        //Setup audio manager that will output sound to speaker
        audioManager = (AudioManager) getSystemService(AUDIO_SERVICE);
        if (audioManager != null) {
            audioManager.setSpeakerphoneOn(true);
        }       
//...OTHER CODE that set up other views and stuff
    }

    //Later onDestroy revert to defaults.
    @Override
    protected void onDestroy() {
        super.onDestroy();
        if (audioManager != null) {
            audioManager.setSpeakerphoneOn(false);
        }
      }
    }

最重要的部分是这个，导入音频管理器：

import android.media.AudioManager;

然后：

AudioManager audioManager = (AudioManager) getSystemService(AUDIO_SERVICE);
if (audioManager != null) {
            audioManager.setSpeakerphoneOn(true);
}
