MediaPlayer Tutorial With Example In Android Studio


In this tutorial we learn how to make android media player .


Media player is combination of audio and video returns an instance of MediaPlayer class
MediaPlayer mediaPlayer = MediaPlayer.create(this, R.raw.demosong);
Mediaplayer object you can call some methods to start or stop the music.

mediaPlayer.start();
mediaPlayer.pause();
start method is used to play song from the beginning.pause start playing from where it is left and not from the beginning
we can reset method
mediaPlayer.reset();
getTrackInfo() is used to array of track information
release() releases any resource attached with MediaPlayer object
getCurrentPosition() returns the current position of song in milliseconds

Example MediaPlayer Android

first we create src/MainActivity.java.
package com.example.welookupsmedia.myapplication;

import android.app.Activity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.os.Handler;
import android.view.View;

import android.widget.Button;
import android.widget.ImageView;
import android.widget.SeekBar;
import android.widget.TextView;
import android.widget.Toast;
import java.util.concurrent.TimeUnit;


public class MainActivity extends Activity {
   private Button b1,b2,b3,b4;
   private ImageView iv;
   private MediaPlayer mediaPlayer;
	
   private double startTime = 0;
   private double finalTime = 0;
	
   private Handler myHandler = new Handler();;
   private int forwardTime = 5000;
   private int backwardTime = 5000;
   private SeekBar seekbar;
   private TextView tx1,tx2,tx3;

   public static int oneTimeOnly = 0;
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);

      b1 = (Button) findViewById(R.id.button);
      b2 = (Button) findViewById(R.id.button2);
      b3 = (Button)findViewById(R.id.button3);
      b4 = (Button)findViewById(R.id.button4);
      iv = (ImageView)findViewById(R.id.imageView);

      tx1 = (TextView)findViewById(R.id.textView2);
      tx2 = (TextView)findViewById(R.id.textView3);
      tx3 = (TextView)findViewById(R.id.textView4);
      tx3.setText("Song.mp3");

      mediaPlayer = MediaPlayer.create(this, R.raw.song);
      seekbar = (SeekBar)findViewById(R.id.seekBar);
      seekbar.setClickable(false);
      b2.setEnabled(false);

      b3.setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
            Toast.makeText(getApplicationContext(), "Playing 
               sound",Toast.LENGTH_SHORT).show();
            mediaPlayer.start();

            finalTime = mediaPlayer.getDuration();
            startTime = mediaPlayer.getCurrentPosition();

            if (oneTimeOnly == 0) {
               seekbar.setMax((int) finalTime);
               oneTimeOnly = 1;
            }
				
            tx2.setText(String.format("%d min, %d sec",
               TimeUnit.MILLISECONDS.toMinutes((long) finalTime),
               TimeUnit.MILLISECONDS.toSeconds((long) finalTime) -
               TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes((long) 
                  finalTime)))
            );

            tx1.setText(String.format("%d min, %d sec",
               TimeUnit.MILLISECONDS.toMinutes((long) startTime),
               TimeUnit.MILLISECONDS.toSeconds((long) startTime) -
               TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes((long) 
                  startTime)))
            );

            seekbar.setProgress((int)startTime);
            myHandler.postDelayed(UpdateSongTime,100);
            b2.setEnabled(true);
            b3.setEnabled(false);
         }
      });

      b2.setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
            Toast.makeText(getApplicationContext(), "Pausing 
               sound",Toast.LENGTH_SHORT).show();
            mediaPlayer.pause();
            b2.setEnabled(false);
            b3.setEnabled(true);
         }
      });

      b1.setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
            int temp = (int)startTime;

            if((temp+forwardTime)<=finalTime){
               startTime = startTime + forwardTime;
               mediaPlayer.seekTo((int) startTime);
               Toast.makeText(getApplicationContext(),"You have Jumped forward 5 
                  seconds",Toast.LENGTH_SHORT).show();
            }else{
               Toast.makeText(getApplicationContext(),"Cannot jump forward 5
                  seconds",Toast.LENGTH_SHORT).show();
            }
         }
      });

      b4.setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
            int temp = (int)startTime;

            if((temp-backwardTime)>0){
               startTime = startTime - backwardTime;
               mediaPlayer.seekTo((int) startTime);
               Toast.makeText(getApplicationContext(),"You have Jumped backward 5 
                  seconds",Toast.LENGTH_SHORT).show();
            }else{
               Toast.makeText(getApplicationContext(),"Cannot jump backward 5 
                  seconds",Toast.LENGTH_SHORT).show();
            }
         }
      });
   }

   private Runnable UpdateSongTime = new Runnable() {
      public void run() {
         startTime = mediaPlayer.getCurrentPosition();
         tx1.setText(String.format("%d min, %d sec",
            TimeUnit.MILLISECONDS.toMinutes((long) startTime),
            TimeUnit.MILLISECONDS.toSeconds((long) startTime) -

            toMinutes((long) startTime)))
         );
         seekbar.setProgress((int)startTime);
         myHandler.postDelayed(this, 100);
      }
   };
}
second we create res/layout/activity_main.xml.
<?xml version="1.0" encoding="utf-8"?>

 <TextView

      android:layout_alignBaseline="@+id/textView2"
      android:layout_alignBottom="@+id/textView2"
      android:layout_centerHorizontal="true" />

</RelativeLayout>

then create res/values/string.xml.
<resources>
   My Application
   
   
   >]]>
   ||

then create AndroidManifest.xml file.

  <application
      android:allowBackup="true"
      android:icon="@drawable/ic_launcher"
