使用 oauth 和 twitter4j 集成 Android Twitter
Posted
技术标签:
【中文标题】使用 oauth 和 twitter4j 集成 Android Twitter【英文标题】：Android Twitter integration using oauth and twitter4j 【发布时间】：2013-07-04 05:01:16 【问题描述】：我想将 twitter 集成到一个 android 应用程序中，并找到了很多教程。实现了其中的 2 个。但是在实现之后，当运行应用程序时，我才知道他们使用的是旧版本的twitter4J 库。
虽然有很多其他教程可用，但它们都不是最新的。即只大2-3个月。我需要一个教程或示例，它使用最新的twitter4J 库版本，即twitter4j-core-3.0.3。
我的主要目标是允许用户在他/她的帐户上发布tweets。但同样，如果用户没有登录，我首先需要询问凭据。另外，如果用户点击logout 按钮，那么我需要一些方法来注销用户。
【问题讨论】：
推特使用OAuth 1.0A @brillenheini 感谢您让我知道这一点。我会相应地编辑我的问题。 跟随本教程tech-papers.org/integrate-twitter-with-android-application Vicky 先生的链接好像坏了 【参考方案1】：我解决了这个问题。我对在教程中找到的代码进行了更改以使其正常工作。在此处复制整个代码。只需替换为您的ConsumerKey 和ConsumerSecret。
您需要将twitter4j 库添加到项目的libs 文件夹中。

这里是 Ravi Tamada 的original code。我所做的更改仅在 MainActivity.java 和 AndroidManifest.xml 文件中。
【讨论】：
你好@akash 你解决了你的问题吗？我使用了 twitter4j 2.3.5 库，其中包含向另一个用户发送推文的方法。如果您还没有解决您的问题，请回复。抱歉回复晚了谢谢。 我试过这段代码，访问令牌返回空请帮助 @Ravi 确保您已在 dev.twitter.com 创建访问令牌。如果您已经尝试删除它们并重新创建。还要检查您的使用者密钥和使用者密码是否已设置。 实际上我解决了问题是因为上面的代码序列，访问令牌是在一个单独的线程中获取的，并且它被保存在主线程中的共享首选项中，因为来自单独线程的代码将在主线程中的代码不固定之后或之前运行，在我的情况下，主线程中的代码在它获取访问令牌之前运行，这就是它为空的原因，所以我将它更改为 asynctask .. 但无论如何都感谢 Ravi Tamada 代码不起作用！请参阅关于错误的评论中的讨论！我收到此错误 01-26 13:02:25.839: E/Twitter Login Error(2022): > null 01-26 13:02:25.839: W/System.err(2022): java.lang.NullPointerException 01- 26 13:02:25.839: W/System.err(2022): 在 com.androidhive.twitterconnect.MainActivity.onCreate(MainActivity.java:200) 01-26 13:02:25.839: W/System.err(2022) : 在 android.app.Activity.performCreate(Activity.java:5243) 01-26 13:02:25.839: W/System.err(2022): 在 android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1087) 【参考方案2】：我找到了一个很好的例子，它适用于 android 上的 twitter4j 3.0.3。其他人不工作。 http://hintdesk.com/how-to-tweet-in-twitter-within-android-client/
【讨论】：
链接不是答案。而且该链接甚至没有提供完整的代码。如果您能够使其正常工作，请发布代码。 @rcompton 该链接是一个完整的教程。无需在此处复制和粘贴所有内容。它没有提供完整的项目，但确实提供了核心代码。学了几天Android编程的人应该都明白了。我用谷歌搜索并尝试了许多示例，但所有示例都无法正常工作。也许那是因为 twitter 将 api 更改为 oauth v1.1 并且这些示例没有更新。此示例是唯一适用于 android 上的 twitter4j 3.0.3 的示例。【参考方案3】：为了说明我上面的评论，这是我最后的工作 MainActivity 类。 与上面的代码非常相似，不同之处在于：
内部类OAuthAccessTokenTask，包括获取 Oauth 令牌和用户信息
它的回调onRequestTokenRetrieved(Exception)
另外，请注意，要使其正常工作，您必须在 twitter 应用设置中声明回调 url，即使是虚假的。我花了几个小时才弄清楚它的工作原理。
当您查看 twitter4j 文档时，前几段代码指的是您必须从授权网页获取的 PIN 码。这就是在您的应用中未设置回调 url 时发生的情况。它被称为基于 PIN 的身份验证，您不想在移动设备上使用它:)

【讨论】：
你的 Twitter Dev 应用设置中的 Twitter 回调 url 必须是 http:// 或 https:// 格式，即使在运行时你的 android 应用会提供它自己的 oauth://t4jsample 值跨度> @daffycricket 您是否面临与***.com/questions/24204855/… 相同的问题？【参考方案4】：这是我的代码中的工作示例，我使用的是 twitter4j，而且你不需要在清单中设置任何意图，因为我使用 webview 而不是浏览器。
放置你的消费者和密钥，你应该很高兴

【讨论】：
您是否面临与***.com/questions/24204855/…相同的问题？ 不，我没有遇到过这个问题，登录后我关闭了我的 webview，所以这个流程不会有这个问题。【参考方案5】：你见过sign-in-with-twittergithub项目吗，它基于twitter4j，实现了Android的Twitter登录。
