I have tried the changes found at the link below but with no avail.
I tried both
AudioManager audioManager = (AudioManager) getApplicationContext().getSystemService(Context.AUDIO_SERVICE);
audioManager.setStreamMute(AudioManager.STREAM_SYSTEM, false);
audioManager.setStreamMute(AudioManager.STREAM_MUSIC,false);
// disable sound for recording.
// disable sound when recording.
((AudioManager)activity.getApplicationContext().getSystemService(Context.AUDIO_SERVICE)).setStreamMute(AudioManager.STREAM_ALARM,true);
((AudioManager)activity.getApplicationContext().getSystemService(Context.AUDIO_SERVICE)).setStreamMute(AudioManager.STREAM_DTMF,true);
((AudioManager)activity.getApplicationContext().getSystemService(Context.AUDIO_SERVICE)).setStreamMute(AudioManager.STREAM_MUSIC,true);
((AudioManager)activity.getApplicationContext().getSystemService(Context.AUDIO_SERVICE)).setStreamMute(AudioManager.STREAM_RING,true);
((AudioManager)activity.getApplicationContext().getSystemService(Context.AUDIO_SERVICE)).setStreamMute(AudioManager.STREAM_SYSTEM,true);
((AudioManager)activity.getApplicationContext().getSystemService(Context.AUDIO_SERVICE)).setStreamMute(AudioManager.STREAM_VOICE_CALL,true);
But I still get the sound when I start the media recorder. I have tried putting this code both at the start of the app and directly before the:
mediaRecorder.start();
Are there any other suggestions?
解决方案 SetStreamMute works only for SYSTEM and MUSIC. For all the other you should use SetStreamVolume.
Try the following code:
AudioManager audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
audioManager.setStreamMute(AudioManager.STREAM_SYSTEM, true);
audioManager.setStreamMute(AudioManager.STREAM_MUSIC,true);
audioManager.setStreamVolume(AudioManager.STREAM_ALARM, 0, 0);
audioManager.setStreamVolume(AudioManager.STREAM_DTMF, 0, 0);
audioManager.setStreamVolume(AudioManager.STREAM_NOTIFICATION, 0, 0);
audioManager.setStreamVolume(AudioManager.STREAM_RING, 0, 0);
For sanity check:
Log.d(TAG, String.format("%d,
%d, %d, %d, %d, %d, %d",
audioManager.getStreamVolume(AudioManager.STREAM_SYSTEM),
audioManager.getStreamVolume(AudioManager.STREAM_MUSIC),
audioManager.getStreamVolume(AudioManager.STREAM_ALARM),
audioManager.getStreamVolume(AudioManager.STREAM_DTMF),
audioManager.getStreamVolume(AudioManager.STREAM_NOTIFICATION),
audioManager.getStreamVolume(AudioManager.STREAM_RING)
The result should give: 0, 0, 0, 0, 0, 0
Keep in mind that the games with volume (exclude setStreamMute) won't reset the previous values after activity dies, so you probably want to store them to restore in onDestroy() or earlier.

我曾尝试在链路发现以下但无济于事的变化。 How状态发生变化时，关闭MediaRecorder播放声音 我都尝试
AudioManager audioManager =（AudioManager）getApplicationContext（）getSystemService（Context.AUDIO_SERVICE）。audioManager.setStreamMute（AudioManager.STREAM_SYSTEM，FALSE）;audioManager.setStreamMute（AudioManager.STREAM_MUSIC，FALSE）; 和
//禁用声音录制。//记录时禁用声音。((AudioManager)activity.getApplicationContext().getSystemService(Context.AUDIO_SERVICE)).setStreamMute(AudioManager.STREAM_ALARM,true);((AudioManager)activity.getApplicationContext().getSystemService(Context.AUDIO_SERVICE)).setStreamMute(AudioManager.STREAM_DTMF,true);((AudioManager)activity.getApplicationContext().getSystemService(Context.AUDIO_SERVICE)).setStreamMute(AudioManager.STREAM_MUSIC,true);((AudioManager)activity.getApplicationContext().getSystemService(Context.AUDIO_SERVICE)).setStreamMute(AudioManager.STREAM_RING,true);((AudioManager)activity.getApplicationContext().getSystemService(Context.AUDIO_SERVICE)).setStreamMute(AudioManager.STREAM_SYSTEM,true);((AudioManager)activity.getApplicationContext().getSystemService(Context.AUDIO_SERVICE)).setStreamMute(AudioManager.STREAM_VOICE_CALL,true); 但我仍然得到的声音时，我开始媒体记录器。我试图把这个code无论是在应用程序的启动和直接前：
mediaRecorder.start（）; 还有没有其他的建议？解决方案
SetStreamMute仅用于系统和音乐。对于所有其他的你应该使用SetStreamVolume。请尝试以下code：
AudioManager audioManager =（AudioManager）context.getSystemService（Context.AUDIO_SERVICE）;
audioManager.setStreamMute（AudioManager.STREAM_SYSTEM，真）;
audioManager.setStreamMute（AudioManager.STREAM_MUSIC，真）;
audioManager.setStreamVolume（AudioManager.STREAM_ALARM，0，0）;
audioManager.setStreamVolume（AudioManager.STREAM_DTMF，0，0）;
audioManager.setStreamVolume（AudioManager.STREAM_NOTIFICATION，0，0）;
audioManager.setStreamVolume（AudioManager.STREAM_RING，0，0）; 有关完整性检查：
Log.d（TAG，的String.format（“％D，％D，％D，％D，％D，％D，％D”
audioManager.getStreamVolume（AudioManager.STREAM_SYSTEM）
audioManager.getStreamVolume（AudioManager.STREAM_MUSIC）
audioManager.getStreamVolume（AudioManager.STREAM_ALARM）
audioManager.getStreamVolume（AudioManager.STREAM_DTMF）
audioManager.getStreamVolume（AudioManager.STREAM_NOTIFICATION）
audioManager.getStreamVolume（AudioManager.STREAM_RING）
））; 结果应该得到：0，0，0，0，0，0 请记住，使用量（不包括setStreamMute）游戏不会复位previous值活动死后，所以你可能要存储它们的onDestroy（）来恢复或更早版本。
