YouTube Api for android exception "service_missing"

I want to play you tube video in my android application I got exception while youtube initialization like "service_missing". I write following code, ``` 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); } } ``` I had also given INTERNET users permission. I test this code in 4.2.2 With google API AVD. android:minSdkVersion="8" android:targetSdkVersion="17" Any one have any idea?? thanks in advance...
