我正在尝试在两个
Android设备Tablet和Mobile(通过Java套接字)之间传输语音/音频(双向).
平板电脑可以清晰播放收到的音频(语音),但手机播放的音频是噪音.
然后我在平板电脑的代码中设置此音频模式：
audioManager.setMode(AudioManager.MODE_IN_CALL);
这导致移动接收清晰的语音.
但平板电脑变得沉默,它不会播放收到的音频(或者说它听不到).
我不确定我应该在这里使用哪种AudioManager模式组合(如果有的话)？
解决方法
可以将您想要播放的声音处理为闹钟.
创建一个名为AlarmController的新类并尝试此代码.
这适用于Android 4.4.2(华为登上P7),每个系统音量(媒体,铃声,闹钟)设置为0.
Context context; MediaPlayer mp; AudioManager mAudioManager; int userVolume; public AlarmController(Context c) { // constructor for my alarm controller class this.context = c; mAudioManager = (AudioManager) context.getSystemService(Context.AUdio_SERVICE); //remeber what the user's volume was set to before we change it. userVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_ALARM); mp = new MediaPlayer(); } public void playSound(String soundURI){ Uri alarmSound = null; Uri ringtoneUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_RINGTONE); try{ alarmSound = Uri.parse(soundURI); }catch(Exception e){ alarmSound = ringtoneUri; } finally{ if(alarmSound == null){ alarmSound = ringtoneUri; } } try { if(!mp.isPlaying()){ mp.setDataSource(context,alarmSound); mp.setAudioStreamType(AudioManager.STREAM_ALARM); mp.setLooping(true); mp.prepare(); mp.start(); } } catch (IOException e) { Toast.makeText(context,"Your alarm sound was unavailable.",Toast.LENGTH_LONG).show(); } // set the volume to what we want it to be. In this case it's max volume for the alarm stream. mAudioManager.setStreamVolume(AudioManager.STREAM_ALARM,mAudioManager.getStreamMaxVolume(AudioManager.STREAM_ALARM),AudioManager.FLAG_PLAY_SOUND); } public void stopSound(){ // reset the volume to what it was before we changed it. mAudioManager.setStreamVolume(AudioManager.STREAM_ALARM,userVolume,AudioManager.FLAG_PLAY_SOUND); mp.stop(); mp.reset(); } public void releasePlayer(){ mp.release(); }
我希望这适合你. 原文链接：https://www.f2er.com/android/318083.html
