使用 oauth 和 twitter4j 的 Android Twitter 集成 [英] Android Twitter integration using oauth and twitter4j
本文介绍了使用 oauth 和 twitter4j 的 Android Twitter 集成的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
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.实施了其中的2个.但是在实施之后，当运行应用程序时，我开始知道他们使用旧版本的 twitter4J 库.>
虽然有很多其他教程可用，但没有一个是最新的.仅大 2-3 个月.我需要一个使用最新 twitter4J 库版本的教程或示例，它是 twitter4j-core-3.0.3.
我的主要目标是允许用户在他/她的帐户上发布推文.但同样，如果用户当时没有登录，我首先需要要求提供凭据.此外，如果用户点击 logout 按钮，那么我需要某种方式来注销用户.
解决方案
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工作.在这里复制整个代码.只需替换为您的 ConsumerKey 和 ConsumerSecret.
您需要将 twitter4j 库添加到您项目的 libs 文件夹中.

I want to integrate twitter in an android application and found many tutorials. Implemented 2 of them. But after implementing, when ran the application, I came to know that they use older version of twitter4J library.
Although plenty other tutorials are available but none of them is latest one.i.e. just 2-3 months older. I need a tutorial or example which uses latest twitter4J library version which is twitter4j-core-3.0.3.
My main aim is to allow user to post tweets on his/her account. But again, if user is not logged in then, I first need to ask for credentials. Also, if user clicks on logout button then I need some way to log the user out.
解决方案
I solved the problem. I made changes to the code I found in a tutorial to make it work. Copying the whole code here. Just replace with your ConsumerKey and ConsumerSecret.
You need to add twitter4j library to your project's libs folder.
