after i read those posts i install eclipse youtube data plug in

and downloaded those file

servlet-api.jar

as mention here https://developers.google.com/gdata/articles/eclipse?hl=iw

those zip file i add to libs folder on my android project exactly like youtube mention in the link above...

to my project i add internet permission, import packages, and add this line : YouTubeService service = new YouTubeService(clientID, developer_key);

like mention here : https://developers.google.com/youtube/2.0/developers_guide_java?hl=iw#Authentication

in this time my project look like this :

package com.example.youtubeuploaddata;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;

import com.google.gdata.client.*;
import com.google.gdata.client.youtube.*;
import com.google.gdata.data.*;
import com.google.gdata.data.geo.impl.*;
import com.google.gdata.data.media.*;
import com.google.gdata.data.media.mediarss.*;
import com.google.gdata.data.youtube.*;
import com.google.gdata.data.extensions.*;
import com.google.gdata.util.*;
import java.io.IOException;
import java.io.File;
import java.net.URL;


public class YoutubeUploadData extends Activity {


    String clientID = "xxxxxxxxxxxxxxx";
    String developer_key = "xxxxxxxxxxxxxxxxxxxxxxx";


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_youtube_upload_data);


        YouTubeService service = new YouTubeService(clientID, developer_key);


    }

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


 }

and my project contein this jar

at this time i test the app on my device and recieve those errors :
