import android.view.Menu;

import com.google.gdata.client.*;
import com.google.gdata.client.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;
    }


 }

Answer 1

Your problem is this:

Caused by: java.lang.NoClassDefFoundError: com.google.common.collect.Maps

com.google.common.collect.Maps is not found. You ether missing a library or have some problem with the manifest.
