Play Youtube 3gp video with MediaPlayer in SurfaceView

This example show how to play YouTube's 3gp video using MediaPlayer, in a SurfaceView.

Modify layout file, /res/layout/activity_main.xml, to add two control buttons (play and stop), and a SurfaceView to hold the media window.

<LinearLayout 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">
    
    <Button
        android:id="@+id/play"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="PLAY"/>
    <Button
        android:id="@+id/stop"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="STOP"/>
    <SurfaceView
        android:id="@+id/mediasurface"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"/>


</LinearLayout>

Modify MainActivity, extends Activity and implements SurfaceHolder.Callback. In the code, path3gp is the path to the Youtube's 3gp video.

package com.example.androidyoutubeplayer;

import java.io.IOException;

import android.graphics.PixelFormat;
import android.media.AudioManager;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.app.Activity;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivity extends Activity implements SurfaceHolder.Callback{
 
 MediaPlayer myMediaPlayer;
 SurfaceView mySurfaceView;
 SurfaceHolder mySurfaceHolder;
 
 Button btnPlay, btnStop;
 
 String path3gp = "rtsp://v8.cache6.c.youtube.com/CjYLENy73wIaLQkP0kiLmutogRMYDSANFEIJbXYtZ29vZ2xlSARSBXdhdGNoYKjR78WV1ZH5Tgw=/0/0/0/video.3gp";
 
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        getWindow().setFormat(PixelFormat.UNKNOWN);
        mySurfaceView = (SurfaceView)findViewById(R.id.mediasurface);        
        mySurfaceHolder = mySurfaceView.getHolder();
        mySurfaceHolder.addCallback(this);
        myMediaPlayer = new MediaPlayer();
        
        btnPlay = (Button)findViewById(R.id.play);
        btnStop = (Button)findViewById(R.id.stop);
        
        btnPlay.setOnClickListener(playOnClickListener);
        btnStop.setOnClickListener(stopOnClickListener);

    }
    
    OnClickListener playOnClickListener
    = new OnClickListener(){

  @Override
  public void onClick(View v) {
   myMediaPlayer.reset();
   
   myMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
   myMediaPlayer.setDisplay(mySurfaceHolder);
   
   try {
    myMediaPlayer.setDataSource(path3gp);
    myMediaPlayer.prepare();
    
    myMediaPlayer.start();
   } catch (IllegalArgumentException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   } catch (SecurityException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   } catch (IllegalStateException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   } catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   }
   
  }};
    
    OnClickListener stopOnClickListener
    = new OnClickListener(){

  @Override
  public void onClick(View v) {
   if(myMediaPlayer.isPlaying()){
    myMediaPlayer.stop(); 
   }
   
  }};

 @Override
 public void surfaceChanged(SurfaceHolder arg0, int arg1, int arg2, int arg3) {
  // TODO Auto-generated method stub
  
 }

 @Override
 public void surfaceCreated(SurfaceHolder holder) {
  // TODO Auto-generated method stub
  
 }

 @Override
 public void surfaceDestroyed(SurfaceHolder holder) {
  // TODO Auto-generated method stub
  
 }
}
