my code is below:

btn.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View arg0) {
        MediaPlayer mp = MediaPlayer.create(MainActivity.this,
        R.raw.click);
        mp.start();
    }
});

Work well but take some time to play after button click. please, anyone, give me a solution. Thanks

I would recommend not using MediaPlayer and use ExoPlayer instead. It is extendable, stable and can play many different types of media. You can find it here: https://github.com/google/ExoPlayer/ — iamgopal, Feb 21 '18 at 05:37

Loading time depends on the buffer size of the MediaPlayer (which is hardcoded in the firmware) and that there is nothing that can be done to change it. Read more here.

This is as a result of the buffer size of media player.

Try using SoundPool for a more responsive playback. You can see an implementation of it here.

SoundPool soundPool = new SoundPool(1, AudioManager.STREAM_MUSIC, 100);
HashMap<Integer, Integer> soundPoolMap soundPoolMap = new HashMap<Integer, Integer>();
soundPoolMap.put(soundID, soundPool.load(this, R.raw.click, 1));

Start the sound with soundPool.play(soundId, 1, 1, 1, 0, 0);

Thanks for the answer, what value i can give to soundID?? – SahdevRajput74 Feb 21 '18 at 05:43
If you have only a single audio clip to be played, then you can do: int soundId = soundPool.load(this, R.raw.click, 1); soundPool.play(soundId, 1, 1, 1, 0, 0); – Deepak Unnikrishnan Feb 21 '18 at 05:59

Option 1:

Instead of creating the media player and then calling start() method in the onClick of the button, you can initialize the mediaPlayer in onCreate() of activity.

As for the button click implementation, you need to call mediaPlayer.start() only.

Option 2: You can use SoundPool API provided by Android. This has lower latency compared to MediaPlayer API. SoundPool are recommended mainly for playing short clips.
