How

Answer 1

This resource explains how to play audio files: https://developer.android.com/guide/topics/media/index.html

You'll probably have to provide your own shutter sound effect.

Answer 2

        AudioManager meng = (AudioManager) getContext().getSystemService(Context.AUDIO_SERVICE);
        int volume = meng.getStreamVolume( AudioManager.STREAM_NOTIFICATION);
        if(volume != 0)
            sound.play(MediaActionSound.SHUTTER_CLICK);

Answer 3

You may want to use SoundPool

SoundPool soundPool = new SoundPool(1, AudioManager.STREAM_NOTIFICATION, 0);
int shutterSound = soundPool.load(this, R.raw.camera_click, 0);

and then to play the sound

soundPool.play(shutterSound, 1f, 1f, 0, 0, 1);

Check out http://developer.android.com/reference/android/media/SoundPool.html to understand the parameters.

You will need a media file called camera_click.ogg in your project at res/raw. You should be able to use the Android default sound which can be obtained from the Android open source project in the following location ( frameworks/base/data/sounds/effects/camera_click.ogg ) if your project is licensed under the Apache license. If your project isn't licensed under the Apache license I have no idea if you can use it or not. I am not a lawyer.

This snippet will help you to play sound only when the ringer mode is in normal mode and not in silent or vibrate.

private var audioManager: AudioManager? = null
private var mediaPlayer: MediaPlayer? = null

private fun initAudio() {
    Log.v(LOG_TAG, "initAudio")

    audioManager ?: let {
        audioManager = context!!.getSystemService(Context.AUDIO_SERVICE) as AudioManager?
    }

    mediaPlayer = try {
        MediaPlayer().apply {
            if (Build.VERSION.SDK_INT >= 21) {
                val audioAttributes = AudioAttributes.Builder()
                    .setUsage(AudioAttributes.USAGE_MEDIA)
                    .setContentType(AudioAttributes.CONTENT_TYPE_MUSIC)
                    .build()
                setAudioAttributes(audioAttributes)
            } else {
                setAudioStreamType(AudioManager.STREAM_MUSIC)
            }
            if (Build.VERSION.SDK_INT <= 28) {
                setDataSource(context!!, Uri.parse("file:///system/media/audio/ui/camera_click.ogg"))
            } else {
                setDataSource(context!!, Uri.parse("file:///system/product/media/audio/ui/camera_click.ogg"))
            }
            prepare()
        }
    } catch (e: Exception) {
        Log.e(LOG_TAG, "initAudio", e)
        null
    }
}

private fun playClickSound() {

    if (audioManager?.ringerMode == AudioManager.RINGER_MODE_NORMAL) {
        mediaPlayer?.start()
    }
}

Answer 5

You can use the MediaActionSound class (available from API 16). For example:

MediaActionSound sound = new MediaActionSound();
sound.play(MediaActionSound.SHUTTER_CLICK);

Answer 6

If the system file is there, you can use it like this:

public void shootSound()
{
    AudioManager meng = (AudioManager) getContext().getSystemService(Context.AUDIO_SERVICE);
    int volume = meng.getStreamVolume( AudioManager.STREAM_NOTIFICATION);

    if (volume != 0)
    {
        if (_shootMP == null)
            _shootMP = MediaPlayer.create(getContext(), Uri.parse("file:///system/media/audio/ui/camera_click.ogg"));
        if (_shootMP != null)
            _shootMP.start();
    }
}
