Not able to achieve Gapless audio looping so far on Android

Question

I have tried almost every method but I\'ve failed to achieve gapless audio playback between looping a single track with a duration of 10-15 seconds.

Steps I\'ve trie

Something like this should work. Keep two copies of the same file in the res.raw directory. Please note that this is just a POC and not an optimized code. I just tested this out and it is working as intended. Let me know what you think.

public class MainActivity extends Activity {
MediaPlayer mp1;
MediaPlayer mp2;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mp1 = MediaPlayer.create(MainActivity.this, R.raw.demo);
    mp2 = MediaPlayer.create(MainActivity.this, R.raw.demo2);

    mp1.start();

    Thread thread = new Thread(new Runnable() {

        @Override
        public void run() {
            int duration = mp1.getDuration();
            while (mp1.isPlaying() || mp2.isPlaying()) {
                try {
                    Thread.sleep(100);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                duration = duration - 100;
                if (duration < 1000) {
                    if (mp1.isPlaying()) {
                        mp2.start();
                        mp1.reset();
                        mp1 = MediaPlayer.create(MainActivity.this,
                                R.raw.demo);
                        duration = mp2.getDuration();

                    } else {
                        mp1.start();
                        mp2.reset();
                        mp2 = MediaPlayer.create(MainActivity.this,
                                R.raw.demo2);
                        duration = mp1.getDuration();
                    }
                }
            }
        }

    });

    thread.start();
}
}
