How to stream an audio in Android?

By | August 14, 2012

This is a simple example to how to stream an audio in android.

Here is the java code for that.

package com.coderzheaven.pack;

import android.app.Activity;
import android.app.ProgressDialog;
import android.media.AudioManager;
import android.media.MediaPlayer;
import android.media.MediaPlayer.OnCompletionListener;
import android.media.MediaPlayer.OnErrorListener;
import android.media.MediaPlayer.OnPreparedListener;
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 StreamAudioDemo extends Activity implements OnClickListener,
OnPreparedListener, OnErrorListener, OnCompletionListener {

    MediaPlayer mp;
    ProgressDialog pd;
    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    Button bt = (Button)findViewById(R.id.play);
    bt.setOnClickListener(this);
}

   @Override
   public void onPrepared(MediaPlayer mp) {
       Log.i("StreamAudioDemo", "prepare finished");
       pd.setMessage("Playing.....");
       mp.start();
  }

  @Override
  public void onClick(View v) {
       try
        {
    	    pd = new ProgressDialog(this);
    	    pd.setMessage("Buffering.....");
    	    pd.show();
            mp = new MediaPlayer();
            mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
            mp.setOnPreparedListener(this);
            mp.setOnErrorListener(this);
            mp.setDataSource("http://www.robtowns.com/music/blind_willie.mp3");
            mp.prepareAsync();
            mp.setOnCompletionListener(this);
        }
        catch(Exception e)
        {
            Log.e("StreamAudioDemo", e.getMessage());
        }
  	}

  	@Override
  	public boolean onError(MediaPlayer mp, int what, int extra) {
      pd.dismiss();
      return false;
  	}

	@Override
	public void onCompletion(MediaPlayer mp) {
		pd.dismiss();
		Toast.makeText(getApplicationContext(), "Completed", Toast.LENGTH_LONG).show();		
	}
}

This is the xml that contains the button.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<Button  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="Stream Audio and Play"
    android:id="@+id/play"
    />
</LinearLayout>

When you run this program you will see a button and on clicking on that button you will see a dialog with message “Buffering…..”. Once the buffering is complete the audio will be start playing.

      Simply put a flag to check whether playing started and change the text of “Play” button to “Pause”.
