stopping the music and playing it again

I tried to make a small music file reader project , I used the code below sow i can play the music and pause it but once I stop it and click on a button to play it from the begining the music is not played I used the code below and I don t know how to solve that problem :

 final MediaPlayer mp=new MediaPlayer();
        mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
 try {
            mp.setDataSource(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS) +String.valueOf("/myfile.mp3"));
        } catch (IOException e) {
            e.printStackTrace();
        }

        btn1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if(!mp.isPlaying()){
                try{
                    mp.prepare();

                }catch(Exception e){e.printStackTrace();}
                    mp.start();
                    btn1.setText("pause");

                }else{
                    mp.pause();
                    btn1.setText("play");

                }
            }
        });



        btn2.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                mp.stop();
                mp.reset();
                btn2.setVisibility(btn2.INVISIBLE);
                btn1.setText("play");

            }
        });

}

Add these lines of code in your btn2 onClick

btn2.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                mp.stop();
                mp.reset();
                btn2.setVisibility(btn2.INVISIBLE);
                btn1.setText("play");

                mp=new MediaPlayer();
        mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
 try {
            mp.setDataSource(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS) +String.valueOf("/myfile.mp3"));
        } catch (IOException e) {
            e.printStackTrace();
        }
            }
        });

It will repair the media player to play again after you reset it.

This is my code implemented as you desired except I am loading music from RAW folder

public class MainActivity extends AppCompatActivity {

    private MediaPlayer mediaPlayer;

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

        final Button stopButton = (Button) findViewById(R.id.button_stop);
        final Button playButton = (Button) findViewById(R.id.button_play);

        mediaPlayer = MediaPlayer.create(getApplicationContext(),R.raw.file);
        playButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                if(!mediaPlayer.isPlaying()){
                    mediaPlayer.start();
                    playButton.setText("pause");
                    stopButton.setVisibility(View.VISIBLE);

                }else{
                    mediaPlayer.pause();
                    playButton.setText("play");

                }
            }
        });



        stopButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mediaPlayer.stop();
                mediaPlayer.reset();
                stopButton.setVisibility(INVISIBLE);
                playButton.setText("play");
                mediaPlayer = MediaPlayer.create(getApplicationContext(),R.raw.file);
            }
        });
    }
}

Option 1 : you can go back from the beginning with mp.seekTo(0); after calling mp.stop(); also remove the mp.reset(); like this:

btn2.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            mp.stop();
            mp.seekTo(0);
            btn2.setVisibility(btn2.INVISIBLE);
            btn1.setText("play");

        }
    });

Option 2 : When calling mp.reset(); you are restoring the object into it's Idle state that's why the music cannot be played. You have to transfer the object into the Initialized state by calling mp.setResource(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS) +String.valueOf("/myfile.mp3")); and then mp.prepare(); like this:

btn2.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            mp.stop();
            mp.reset();
            btn2.setResource(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS) +String.valueOf("/myfile.mp3"));
            mp.prepare();
            btn1.setText("play");

        }
    });

I suggest that you go for Option 1

I hope this helps. I haven't done any android programming but I know some Java and read the details about the MediaPlayer right here.

From the state machine of the documentation, it seems that you have to use 

mp.stop()
mp.prepare()
mp.start()

This would complete the state machine.
