I have a lot of sounds to play but not this default sound, I don't know where this sound come from ? 

 private final ShutterCallback mShutterCallback = new ShutterCallback();    
//when i take it
        mCameraDevice.takePicture(mShutterCallback, mRawPictureCallback,
                    mPostViewPictureCallback, new JpegPictureCallback(loc));    

    private final class ShutterCallback implements
            android.hardware.Camera.ShutterCallback {
        public void onShutter() {
            mShutterCallbackTime = System.currentTimeMillis();
            mShutterLag = mShutterCallbackTime - mCaptureStartTime;
            Log.v(TAG, "mShutterLag = " + mShutterLag + "ms");
            clearFocusState();
        }
    }

    Bear in mind that this may be [illegal in some countries](https://www.google.com/search?client=safari&rls=en&q=japan+shutter+sound+law&ie=UTF-8&oe=UTF-8). – Matt Gibson Jan 20 '15 at 09:42

Use Below code before getting the button clicked

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

And these two lines just after the image get captured:

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