Answer 1

to play song again reset media player, set data source again and start

mp.reset();
mp.setDataSource(MEDIA_PATH);
mp.prepare();
mp.start();

Verisimilar

I'm sure this is correct, but the state diagram presented in the documentation doesn't seem to support this assertion. I feel like the MediaPlayer API is poorly designed in general. – Commutation

what if song play in looping? how to reset? – Monongahela

Answer 2

When press play button after stop ,then play button never works--for this problem we can create object again in stop button. for eg;-stop.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            if(mPlayer.isPlaying())
            mPlayer.stop();
            mPlayer  = MediaPlayer.create(mediaplayeractivity.this, R.raw.adidas);
        }
    });}

You can check this Demo Example Here, i am looping a Audio clicp continously and stopping on Button Cick and playing again.

import static java.util.concurrent.TimeUnit.SECONDS;

public class MainActivity extends AppCompatActivity {

    Button scan;
    Button stop;

    MediaPlayer mp;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        scan=(Button)findViewById(R.id.scan);
        stop=(Button)findViewById(R.id.stop);
        mp = MediaPlayer.create(this, R.raw.trackeralertseparation);
        scan.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                mp.setLooping(true);
                mp.start();
                mp.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
                    @Override
                    public void onCompletion(MediaPlayer mediaPlayer) {
                        mp.reset();
                        mp.release();
                    }
                });
            }
        });

        stop.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                if(mp.isPlaying()){
                    mp.stop();
                }
                mp=MediaPlayer.create(getApplicationContext(), R.raw.trackeralertseparation);
            }
        });
    }
}

The Design File is Below with simple Button.

<?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        tools:context=".MainActivity">


        <Button
            android:id="@+id/scan"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentTop="true"
            android:layout_centerHorizontal="true"
            android:layout_marginTop="195dp"
            android:gravity="center_vertical"
            android:padding="4dp"
            android:text="Play"
            android:textSize="26sp"
            android:textStyle="bold" />

        <Button
            android:id="@+id/stop"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="stop"
            android:padding="4dp"
            android:layout_centerInParent="true"
            android:textSize="26sp"
            android:textStyle="bold"/>

    </RelativeLayout>

Answer 4

Then you should use pause function instead of stop

mediaplayer.pause();

by this you can play it again easily by

mediaplayer.start();

Answer 5

Easy solution is don't call stop() function. Call below 2 functions instead.

    mp.seekTo(0)
    mp.pause()

This is kotlin code and java are same just with ; after each line. Here mp es mediaPlayer object reference. seekTo(0) will take the media player to first position and pause() function will pause the player. When user will click play again it will play normally without any issue.

Answer 6

When the play wont work after you hit the stop button... just make your mediaplayer object as an object array that should fix it..

final MediaPlayer[] mediaPlayer = {MediaPlayer.create(getApplicationContext(), R.raw.song_name)};

stop.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            mediaPlayer[0].stop();

            mediaPlayer[0] = MediaPlayer.create(getApplicationContext(),R.raw.song_name);
        }
    });

This seems like a really weird solution. What are the benefits of having an array of MediaPlayer objects? – Requisition

I am not sure how this works .. But anyway we will be using only one MediaPlayer Object ie .. mediaPlayer[0] @Requisition – Mandiemandingo

Well I don't think there's ever an instance where you should have more than one media player... but if it works and you don't see any significant performance issues then it guess it's all good Edit: What I mean is that you should pause and start the same media player if you want to play 2 different songs – Requisition

Answer 7

When you stop music, must declare the song again in create.

the easy way using Android Studio:

mPlayer  = MediaPlayer.create(mediaplayeractivity.this, R.raw.adidas);
