Stop Camera Click Sound Programmatically In Android

I am using android's default camera to click images from within my app. I want to stop the click sound that it does on clicking an image. Is there a way to stop that click sound pr

Solution 1:

I was able to successfully use the trick to turn the volume down. I did this just before taking the picture:

AudioManagermgr= (AudioManager)getSystemService(Context.AUDIO_SERVICE);
    mgr.setStreamMute(AudioManager.STREAM_SYSTEM, true);

And this just after getting the first message back:

AudioManagermgr= (AudioManager)getSystemService(Context.AUDIO_SERVICE);
    mgr.setStreamMute(AudioManager.STREAM_SYSTEM, false);

Solution 2:

To disable sound use this code:

AudioManagermgr= (AudioManager)getSystemService(Context.AUDIO_SERVICE);
intstreamType= AudioManager.STREAM_SYSTEM;
mgr.setStreamSolo(streamType, true);
mgr.setRingerMode(AudioManager.RINGER_MODE_SILENT);
mgr.setStreamMute(streamType, true);

To enable sound use this code:

mgr = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
streamType = AudioManager.STREAM_SYSTEM;
mgr.setStreamSolo(streamType, false);
mgr.setRingerMode(AudioManager.RINGER_MODE_SILENT);
mgr.setStreamMute(streamType, false);

Solution 3:

For my Nexus S running 4.0.3,

AudioManager.STREAM_SYSTEM

does not prevent camera shutter sound from emitting, but

AudioManager.STREAM_MUSIC

works!

Solution 4:

You can mute and unmute your device using the code below:

finalAudioManagermode= (AudioManager)   this.getSystemService(Context.AUDIO_SERVICE);
 //Silent Mode Programatically
 mode.setRingerMode(AudioManager.RINGER_MODE_SILENT);

//Normal Mode Programatically
mode.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
