我正在下载 task-android-sample( http://code.google.com/p/google-api-java-client/issues/detail?id=479 )。但是当我在我的安卓设备上运行这个例子时，我得到了错误

错误出现在此函数中

protected void doInBackground() throws IOException {
Log.d(Tag, "doInBackground");
List<String> result = new ArrayList<String>();
List<Task> tasks =
    client.tasks().list("@default").setFields("items/title").execute().getItems();
Log.d(Tag, "трассировка");
if (tasks != null) {
  for (Task task : tasks) {
    result.add(task.getTitle());
  }
} else {
  result.add("No tasks.");
}
activity.tasksList = result;

}

描述客户端

final com.google.api.services.tasks.Tasks client;
client = activity.service;

可能是什么问题？我是新手，请帮忙。

 public static final String KEY = null;

确保您添加了 key 代替 null inClientCredentials.java

String message = t.getMessage();
if (t instanceof GoogleJsonResponseException) {
  GoogleJsonError details = ((GoogleJsonResponseException) t).getDetails();
  if (details != null) {
    message = details.getMessage();
  }
} else if (t.getCause() instanceof GoogleAuthException) {
  message = ((GoogleAuthException) t.getCause()).getMessage();
}
showError(activity, message);
  }

/**

  }


  public static void showError(Activity activity, String message) {

showErrorInternal(activity, errorMessage);
  }

  private static void showErrorInternal(final Activity activity, final String errorMessage) {
activity.runOnUiThread(new Runnable() {
  public void run() {
    Toast.makeText(activity, errorMessage, Toast.LENGTH_LONG).show();
  }
    });
  }

  private static String getErrorMessage(Activity activity, String message) {
Resources resources = activity.getResources();
if (message == null) {
  return resources.getString(R.string.error);
}
return resources.getString(R.string.error_format, message);
  }
}

这是我的代码。我能解决什么问题？
