我想使用谷歌产生的API库首次为Android。我已经采取了code从该示例程序由谷歌提供。我的code看起来像

I am trying to use the Google generated API library for the first time for Android. I have taken code from the the Sample Program provided by Google. My code looks like

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

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

// Core Google API
import com.google.api.client.auth.oauth2.draft10.AccessTokenResponse;
import com.google.api.client.googleapis.auth.oauth2.draft10.GoogleAccessProtectedResource;
import com.google.api.client.googleapis.auth.oauth2.draft10.GoogleAccessTokenRequest.GoogleAuthorizationCodeGrant;
import com.google.api.client.googleapis.auth.oauth2.draft10.GoogleAuthorizationRequestUrl;
import com.google.api.client.http.ByteArrayContent;
import com.google.api.client.http.GenericUrl;
import com.google.api.client.http.HttpRequest;
import com.google.api.client.http.HttpRequestFactory;
import com.google.api.client.http.HttpResponse;
import com.google.api.client.http.HttpTransport;
import com.google.api.client.http.javanet.NetHttpTransport;
import com.google.api.client.json.JsonFactory;
import com.google.api.client.json.jackson.JacksonFactory;

// Google+ API
import com.google.api.services.plus.*;

public class GooglePlusActivity extends Activity {

    // Want data about authenticated user
    private static final String SCOPE = "https://www.googleapis.com/auth/plus.me";
    //
    private static final String CALLBACK_URL = "urn:ietf:wg:oauth:2.0:oob";
    //
    private static final HttpTransport TRANSPORT = new NetHttpTransport();
    private static final JsonFactory JSON_FACTORY = new JacksonFactory();

    private static final String CLIENT_ID = "XXXXXXXXXXXXXXX";
    private static final String CLIENT_SECRET = "XXXXXXXXXXXXXX";

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        // Generate the URL to which we will direct users
        String authorizeUrl = new GoogleAuthorizationRequestUrl(CLIENT_ID,
                CALLBACK_URL, SCOPE).build();

        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));

        try {
            String authorizationCode = in.readLine();

            // Exchange for an access and refresh token
            GoogleAuthorizationCodeGrant authRequest = new GoogleAuthorizationCodeGrant(TRANSPORT,
                JSON_FACTORY, CLIENT_ID, CLIENT_SECRET, authorizationCode, CALLBACK_URL);

            authRequest.useBasicAuthorization = false;

            AccessTokenResponse authResponse = authRequest.execute();

            String accessToken = authResponse.accessToken;

            GoogleAccessProtectedResource access = new GoogleAccessProtectedResource(accessToken,
                TRANSPORT, JSON_FACTORY, CLIENT_ID, CLIENT_SECRET, authResponse.refreshToken);

            HttpRequestFactory rf = TRANSPORT.createRequestFactory(access);
            System.out.println("Access token: " + authResponse.accessToken);


        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        Plus plus = new Plus(new NetHttpTransport(), new JacksonFactory());

    }
}

但是下面一行：

However the following line:

private static final HttpTransport TRANSPORT = new NetHttpTransport();

会导致异常：

cause an exception:

10-04 13:33:28.954: ERROR/AndroidRuntime(5925): Caused by: java.lang.NoClassDefFoundError: com.google.api.client.http.javanet.NetHttpTransport

我已经加入到构建路径以下库：

I have the following libraries added to the build path:

谷歌API的客户端1.5.0-beta.jar 谷歌-API的服务加v1-1.2.2-beta.jar

google-api-client-1.5.0-beta.jar google-api-services-plus-v1-1.2.2-beta.jar

和这些依赖库：

番石榴-R09 HttpClient的-4.0.3 杰克逊核心ASL-1.6.7 GSON-1.6

guava-r09 httpclient-4.0.3 jackson-core-asl-1.6.7 gson-1.6

我添加的依赖才走出绝望......因为我不能看到，我需要他们。我所有的import语句在编译时正确解析，所以我为什么会得到这个错误？

I added the dependencies only out of desperation...since I cannot see that I need them. All my import statements are resolved correctly at compile time, so why would I get this error?

我使用的Eclipse靛蓝在Windows 7上。

I'm using Eclipse Indigo on Windows 7.

我添加了以下jar文件：

I added the following jar files:

谷歌API的客户端1.5.0-β 谷歌-API的客户扩展-1.5.0-β 谷歌-API客户端 - 扩展 - android2-1.5.0-β 谷歌-API的服务加v1-1.2.2-β 谷歌-HTTP客户端-1.5.0-β 谷歌-HTTP客户端，扩展-1.5.0-β 谷歌-HTTP客户端 - 扩展 - android2-1.5.0-β 谷歌-支持OAuth客户端1.5.0-β 谷歌-支持OAuth客户扩展-1.5.0-β GSON-1.6 番石榴-R09 HttpClient的-4.0.3 的HttpCore-4.0.1 杰克逊核心ASL-1.6.7

google-api-client-1.5.0-beta google-api-client-extensions-1.5.0-beta google-api-client-extensions-android2-1.5.0-beta google-api-services-plus-v1-1.2.2-beta google-http-client-1.5.0-beta google-http-client-extensions-1.5.0-beta google-http-client-extensions-android2-1.5.0-beta google-oauth-client-1.5.0-beta google-oauth-client-extensions-1.5.0-beta gson-1.6 guava-r09 httpclient-4.0.3 httpcore-4.0.1 jackson-core-asl-1.6.7

这解决了我的问题。但是我仍然不知道如何将这些文件对应的库列表中的wiki页面上也是为什么他们需要我的时候进口在编译期间得到解决。

this resolved my problem. However I am still unsure about how these files correspond to the libraries list on the wiki page and also why they're required when my imports are resolved during compile time.
