Android Twitter 无法检索访问令牌

Question

我在调用时收到错误“请求令牌或令牌密码未在服务器回复中设置。您使用的服务提供商可能有问题。”

provider.RetrieveAccesstoken(comsumer, verifier);

但奇怪的是我有时只会收到此错误。首先，我的代码有效，我发布了一条消息。然后第二天我尝试在我的

上重新安装该应用程序

家用电脑我收到了这个错误。回到我的工作站，我再次遇到了同样的错误，但在按下启动程序的按钮后，它再次工作并且

在 Twitter 上发布了一条消息。这到底是怎么回事？！谁能解释一下？

我在 android 2.2 上运行了 2 个模拟器，它在 WQVGA400 上运行的频率更高，然后在 WVGA800 模拟器上运行：S

我还收到通知“BufferedReader 构造函数中使用的默认缓冲区大小。如果需要 8k 字符的缓冲区，最好是明确的。”

这是否与我的记忆或存储令牌机密有关？听起来服务太忙，无法在联系时回复。

为了便于阅读，我删除了异常和导入

成功了！ 而不是使用 Oath 路标库

provider.retrieveAccessToken(consumer,verifier)

我使用了 twitter4j 库

getOAuthAccessToken(requestToken, 验证者)

    String verifier = uri.getQueryParameter(OAuth.OAUTH_VERIFIER);
    Twitter twitter = new TwitterFactory().getInstance();
    twitter.setOAuthConsumer(CONSUMER_KEY, CONSUMER_SECRET);
    AccessToken accessToken = null;//get stored request tokens from database
    mDbHelper = DbAdapter.getInstance();
    mDbHelper.open();
    String[] dbRequestTokens = mDbHelper.getTwitterRequestTokens();
    mDbHelper.close();
    RequestToken requestToken = new RequestToken(dbRequestTokens[0], dbRequestTokens[1]);
    try {
        accessToken = twitter.getOAuthAccessToken(requestToken, verifier);
        //dataBase store accessTokens to tweet message  or acces other twitter recources, and don't forget to set the OAuth Consumer with consumer key and secret
        mDbHelper.open();
        mDbHelper.setTwitterAccessTokens(accessToken.getToken(), accessToken.getTokenSecret());
        mDbHelper.close();
        return "logged in succesfully";
        } catch (TwitterException e) {
        e.printStackTrace();
        return e.getMessage();
    }
