Google 任务身份验证错误
我已经开始编写一个 Android 应用程序,该应用程序实现了 ListView 和简单的数据库,并提供了从特定 Google 帐户接收任务并将其添加到 ListView 的机会。
我使用了这个 教程和任务API 来实现代码,但它不起作用,而且网上也没有太多其他教程。这是我的开始活动的片段。
我在手机上只创建了一个帐户,因此我省略了“选择帐户”-对话框:
googleAccountManager = new GoogleAccountManager(RememberMe.this);
Account[] accounts = googleAccountManager.getAccounts();
account = accounts[0];
googleAccountManager.manager.getAuthToken(account, AUTH_TOKEN_TYPE, null, this, new AccountManagerCallback<Bundle>()
{
public void run(AccountManagerFuture<Bundle> future)
{
try
{
// If the user has authorized your application to use the tasks API
// a token is available.
String token = future.getResult().getString(AccountManager.KEY_AUTHTOKEN);
HttpTransport transport = AndroidHttp.newCompatibleTransport();
GoogleAccessProtectedResource googleAccessProtectedResource = new GoogleAccessProtectedResource(token);
service = new Tasks(transport, googleAccessProtectedResource, new JacksonFactory());
service.setKey("AIzaSyDAnO-UGa_zJnqftSVTHnvoHDp8Tfrmtko");
service.setApplicationName("Remember Me");
receivingTasks();
// Now you can use the Tasks API...
}
catch (OperationCanceledException e)
{
// TODO: The user has denied you access to the API, you should handle that
Log.w(TAG, "synchronize - Catch OperationCanceled Exception");
}
catch (Exception e)
{
Log.w(TAG, "synchronize - Catch Exception e");
}
}
}, null);
这是“接收任务”-方法:
public void receivingTasks()
{
try
{
TaskLists taskLists = service.tasklists.list().execute();
for (TaskList taskList : taskLists.getItems())
{
Log.w(TAG, "" + taskList.getTitle());
}
}
catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}
一切正常-我得到了一个令牌,有一个服务对象和一个帐户对象-但是当我们到达
TaskLists taskLists = service.tasklists.list().execute();
它时,它会抛出异常并且没有任何反应,所以我猜任务列表 - 对象没有初始化,但我不知道为什么“它无法响应”(LogCat)。
这是 LogCat:

我还想知道教程和 API 之间的区别在哪里,如果有人可以帮助我,那就太好了,因为我不知道还能在哪里找到有关此主题的帮助。 多谢。
I've started programming an Android application which implements a ListView and a simple Database and offers the opportunity to receive tasks from a specific Google Account and than add them to the ListView.
I used this Tutorial and the Tasks API to implement the code, but it doesn't work and there aren't many other tutorials on the web. Here's a snippet of my Start-Activity.
I created only one account on my phone, so I left out the 'Choose Accounts'-Dialog:
googleAccountManager = new GoogleAccountManager(RememberMe.this);
Account[] accounts = googleAccountManager.getAccounts();
account = accounts[0];
googleAccountManager.manager.getAuthToken(account, AUTH_TOKEN_TYPE, null, this, new AccountManagerCallback<Bundle>()
{
public void run(AccountManagerFuture<Bundle> future)
{
try
{
// If the user has authorized your application to use the tasks API
// a token is available.
String token = future.getResult().getString(AccountManager.KEY_AUTHTOKEN);
HttpTransport transport = AndroidHttp.newCompatibleTransport();
GoogleAccessProtectedResource googleAccessProtectedResource = new GoogleAccessProtectedResource(token);
service = new Tasks(transport, googleAccessProtectedResource, new JacksonFactory());
service.setKey("AIzaSyDAnO-UGa_zJnqftSVTHnvoHDp8Tfrmtko");
service.setApplicationName("Remember Me");
receivingTasks();
// Now you can use the Tasks API...
}
catch (OperationCanceledException e)
{
// TODO: The user has denied you access to the API, you should handle that
Log.w(TAG, "synchronize - Catch OperationCanceled Exception");
}
catch (Exception e)
{
Log.w(TAG, "synchronize - Catch Exception e");
}
}
}, null);
Here is the 'receiveTasks'-Method:
public void receivingTasks()
{
try
{
TaskLists taskLists = service.tasklists.list().execute();
for (TaskList taskList : taskLists.getItems())
{
Log.w(TAG, "" + taskList.getTitle());
}
}
catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Everything's working fine - I get a token, there's a service-Object and a Account-Object - but when we get to
TaskLists taskLists = service.tasklists.list().execute();
it throws an exception and nothing happens, so I guess the TaskLists - Object isn't initialized, but I have no idea why "it is unable to respond" (LogCat).
Here's the LogCat:
11-29 15:57:58.848: W/DefaultRequestDirector(2878): Authentication error: Unable to respond to any of these challenges: {authsub=WWW-Authenticate: AuthSub realm="https://www.google.com/accounts/AuthSubRequest" allowed-scopes="https://www.googleapis.com/auth/tasks,https://www.googleapis.com/auth/tasks.readonly"}

11-29 15:57:58.868: W/System.err(2878): at com.google.api.services.tasks.Tasks$Tasklists$List.execute(Tasks.java:1262)
I also wonder where the different between the tutorial and the API is, it would be great if someone could help me, because i don't know where else i could find help about this topic.
Thanks a lot.

对于遇到同样问题的每个人,请尝试将令牌保存在共享首选项中,并在每次启动应用程序时使其失效,并由于帐户管理器的错误而生成新的令牌;我的问题可以这样解决:
看这个:

For everybody who got the same problem, try to save the token in the Shared Preferences and invalidate it every time the application is started and generate a new one due to a bug of the Account Manager; my problem could be solved this way:
