How to stop activity when user presses Home?

I am creating a music application. I'm having a problem: when the user presses back/home, the music continues playing.

Here is my APK file

How can I allow the user to return to Main Activity and clear the current activity (playing music)?

Try to override the onWindowsFocusChanged(boolean hasFocus) method.

When the user clicks back button the control goes inside the following method (Insert this method in your code)

    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
    super.onKeyDown(keyCode, event);
            if (keyCode == KeyEvent.KEYCODE_BACK) {
                    // code to pause or stop the music!!!!
            }
            **return false;**
        }

toggle between the onpause and onstart is important The onPause() method is overrided to give playerback control to this instance. also u can refer this

package org.example.audio;

import android.app.Activity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;

public class AudioDemo extends Activity implements OnClickListener {
    private static final String TAG = "AudioDemo";
    private static final String isPlaying = "Media is Playing"; 
    private static final String notPlaying = "Media has stopped Playing"; 

    MediaPlayer player;
    Button playerButton;

    public void onClick(View v) {
        Log.d(TAG, "onClick: " + v);
        if (v.getId() == R.id.play) {
            playPause();
        }
    }

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        player = MediaPlayer.create(this, R.raw.robotrock);
        player.setLooping(false); // Set looping

        // Get the button from the view
        playerButton = (Button) this.findViewById(R.id.play);
        playerButton.setText(R.string.stop_label);
        playerButton.setOnClickListener(this);

        // Begin playing selected media
        demoPlay();

        // Release media instance to system
        player.release();

    }

    @Override
    public void onPause() {
        super.onPause();
        player.pause();
    }

    // Initiate media player pause
    private void demoPause(){
            player.pause();
            playerButton.setText(R.string.play_label);
            Toast.makeText(this, notPlaying, Toast.LENGTH_LONG).show();
            Log.d(TAG, notPlaying);
    }

    // Initiate playing the media player
    private void demoPlay(){
            player.start();
            playerButton.setText(R.string.stop_label);
            Toast.makeText(this, isPlaying, Toast.LENGTH_LONG).show();
            Log.d(TAG, isPlaying);
    }

    // Toggle between the play and pause
    private void playPause() {
        if(player.isPlaying()) {
          demoPause();
        } else {
          demoPlay();
        }   
    }
}

You can use your onPause() of your Activity to stop or pause the Mediaplayer.

Override the onPause() like this, 

@Override
protected void  onPause()
{
    super.onPause();
  if(mediaplayer!=null)
{
    mediaplayer.pause();
}
}

And when you enter your activity once again, override the onResume() like this, 

@Override
            protected void onResume() {
                super.onResume();

 if(mediaplayer!=null)
{
    mediaplayer.start();
}
}

You need to override onPause() or onStop() and stop the music there.
