Answer 1

Whenever you need to wait for a specific period of time in a single thread, you can use:

try {
    Thread.sleep(millis);
} catch (InterruptedException e) { }

Answer 2

By using Thread.sleep() or SystemClock.sleep() this causing blocking/freezing of Main thread of the app,
I suggest using Handler.postDelayed() instead

firstly add your media file under res/raw directory, If isn't exist you must create it.

right click on res directory >> new >> Android Resource Directory

on Resource type choose raw, then copy your media file to it for example "song.mp3"

the code

public class MainActivity extends AppCompatActivity {

//Creating MediaPlayer object
    private MediaPlayer player;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
            player = MediaPlayer.create
            (MainActivity.this, R.raw.song); // >> here's choose your song file
                player.start();
            }
        }, 10000); // >> Put time with milliseconds, this will delay the start play for 10 seconds
}

you may want to stop the song by override onStop method like this

@Override
protected void onStop() {
    super.onStop();
    if (player.isPlaying())
        player.stop();
}

Answer 3

you can use

 new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
           //your code
          }
        }, 10000);
