【中文标题】从 Android 应用程序发布 LinkedIn 消息【英文标题】:Posting LinkedIn message from Android application 【发布时间】:2011-08-13 20:08:39 【问题描述】:我想将我的 android 应用程序与 LinkedIn 集成并发布消息。谁能提供一个例子来说明如何做到这一点?
【问题讨论】:
【参考方案1】:你甚至尝试过谷歌吗? 来自http://developer.linkedin.com/docs/DOC-1255 我们得到了 http://code.google.com/p/linkedin-j/
编辑: 这是我的示例项目http://esilo.pl/LITest.zip
EDIT2:最小样本,令牌存储在 SharedPreferences 中(因此您无需每次都进行授权(我将更新 LITest.zip))
EDIT3:添加了 AsyncTask 代码...以避免 NetworkOnMainThreadException :)

【讨论】:
是的,我试试看.. 并从 google svn 结帐。但是在这个链接中code.google.com/p/linkedin-j/wiki/GettingStarted accessTokenValue 和 tokenSecretValue 是什么意思? 我也使用了它,但是在获取 requestToken 时出现错误,我用代码developer.linkedin.com/thread/3034 plz help 发布我的问题 样本基于code.google.com/p/linkedin-j/wiki/AndroidConfiguration => esilo.pl/LITest.zip ... 15 分钟完成 您好 Selvin,请帮帮我...我在这里发布了问题...***.com/questions/8562584/… 嗨 Selvin 在这个例子中我得到了名字,姓氏,但是如何获取登录的特定用户的 ID ...所以告诉你这样做..【参考方案2】:非常有帮助的答案@Selvin!
此代码应该在 Honeycomb (API 11) 之前的目标上正常工作,但它会在(发布)API 11 上出现 NetworkOnMainThreadException 失败。在 IAPI 11 之前,最好避免在 UI 线程上运行(可能很长的)网络活动,因为它可能会锁定它。
我更新了 Selvin 的代码,使其与 API 10 兼容。

希望有人觉得这很有用!归功于 Selvin。
【讨论】:
你绝对有用.. 因为 NetworkOnMainThreadException 将在 api 级别 10 之后发生.. 但它在 api 级别 11 以下运行良好。 @dmmh 当我制作这个样本时,没有使用 API 11 的设备 :) 很好的解决方案,但你测试了吗?我不确定tv.setText
是否可以在非 UI 线程上完成...
好的,好吧,我在我的答案中修正了我愚蠢的编码错误......现在一切都经过测试并且正在运行!再次感谢伙计!
您好,如何使用本示例获取 ID-- Log.e("Id Of User","Id Of user"+p.getId());
关于库的可怕文档,但这就是为什么您不能在自己的个人资料中使用 getId() 的原因:code.google.com/p/linkedin-j/issues/detail?id=58。更多关于现场选择器的信息:developer.linkedin.com/documents/field-selectors以上是关于从 Android 应用程序发布 LinkedIn 消息的主要内容,如果未能解决你的问题,请参考以下文章
