问题描述
|
首先。是否可以通过Facebook，Twitter等Android应用程序添加linkedin？我已经阅读了许多博客，但是无法在我的应用程序中实现linkedin。我已经进入应用程序的用户授权过程，在该过程中，用户输入了他的用户名和密码。但是当他输入5位数字时，屏幕上会出现，并且屏幕显示已到达应用程序主屏幕。然后填充它，然后按Enter。
但是问题是，我该如何从浏览器移回我的应用程序，以及用户应在何处放置此数字数据。以及何时及如何获取访问令牌以使用用户个人资料的数据。
互联网上没有什么好事可用于android的linkedin。我有一个图书馆http://code.google.com/p/linkedin-j/，但是如何克服情况呢？不知道。谁能建议我一些解决方案。谢谢。
解决方法
您可以使用第三方jar scribe.jar来实现。
如下调用webview意图授权。
