Android 上的 Google 联系人数据 API 不起作用？

Question

我尝试在 Android 上使用 Google Contacts Data API，更具体地说是 ContactsService 类，但在我尝试实例化 ContactsService 类时应用程序崩溃。

普通的 Java 应用程序没有这个问题。

例如，下面的代码工作正常

public class TestJava { 
    public static void main(String[] args) {        
        ContactsService myService = new ContactsService("TestApp");
        System.out.println("OK");       
    }   
}

但是，在 Android 应用程序下方崩溃（我将 Internet 权限放在清单中）

public class TestAndroidActivity extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        ContactsService myService = new ContactsService("TestApp");
        System.out.println("OK");

    }
}

有人知道 Google 联系人数据 API 是否适用于 Android 系统吗？ 我错过了清单中的权限吗？

提前致谢。

编辑：

我在 Eclipse 中使用了两个项目来测试上面的代码：一个 Java 项目和一个 Android 项目。

两个项目共享相同的库，只有 Android 项目崩溃。

这里是错误信息：

Answer 1

我认为你遇到了这种类型的错误

Exception in thread "main" java.lang.NoClassDefFoundError: com/google/common/collect/Maps

您是否添加了 google-collect-1.0-rc1.jar 文件？如果没有，那么我确定你得到了错误，这是依赖文件。

您可以从this site 下载此文件并下载并添加到您的项目中。
