YouTube Api for Android異常「service_missing」

我想在您的Android應用程序中播放管視頻YouTube Api for Android異常「service_missing」

當youtube初始化像「service_missing」時，我得到了異常。

我寫下面的代碼，

package com.example.youtubedemo; 
import android.os.Bundle; 

import android.view.Menu; 
import android.widget.Toast; 
import com.google.android.youtube.player.*; 
import com.google.android.youtube.player.YouTubePlayer.OnInitializedListener; 
import com.google.android.youtube.player.YouTubePlayer.Provider; 

public class MainActivity extends YouTubeBaseActivity implements OnInitializedListener{ 

    static private final String DEVELOPER_KEY = "MY API KEY"; 

    static private final String VIDEO = https://www.youtube.com/watch?v=d6XXgeAkBfQ&list=PLWz5rJ2EKKc9Wam5jE-9oY8l6RpeAx-XM"; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     YouTubePlayerView youTubeView = (YouTubePlayerView) 
       findViewById(R.id.youtube_view); 
     youTubeView.initialize(DEVELOPER_KEY, MainActivity.this); 
    } 



    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.main, menu); 
     return true; 
    } 



    @Override 
    public void onInitializationFailure(Provider arg0,YouTubeInitializationResult error) { 
     Toast.makeText(this, "Oh no! "+error.toString(),Toast.LENGTH_LONG).show(); 

     Toast.makeText(this, ""+YouTubeInitializationResult.SERVICE_MISSING,Toast.LENGTH_LONG).show(); 
    } 



    @Override 
    public void onInitializationSuccess(Provider arg0, YouTubePlayer player, 
      boolean arg2) { 
     player.loadVideo(VIDEO); 

    } 

}
