如何使用yamba-8教程在android中的Status.Net中发布状态更新

标签： android twitter

实际上，我在Android中遇到了问题。我正在创建一个连接到Twitter的应用程序，如应用程序Status.Net。我使用自己的用户名和密码在此站点中创建了一个帐户。现在我创建的应用程序连接到此Status.Net站点。最初，这个Android应用程序是从Marko Gargenta的一个名为Learning Android的学习Android网站中挑选出来的，我已经从它的git下载了源代码。我通过将不同的API根目录指定为farmnews.aaditech.com/api（最初API根为http://yamba.marakana.com/api）来创建我自己的此应用程序版本。原始API root的代码工作正常。它更新了yamba.marakana.com中的状态，状态也显示在时间线中。但是当我指定自己的API根目录时，它只是更新到status.net并显示一个toast消息“Failed To Post”，它不应该是bcoz，它显然是在status.net上发布的。我不知道是什么问题。但我知道如果我只改变API根的一行，一切都会正常工作。

我尝试使用其他API根网址http://identi.ca/api，但似乎没有工作

请帮帮我
问候和谢谢 Sohaib Rahman

答案 0 :(得分：2)

我遇到了同样的问题，identi.ca API似乎没有返回以下值：

profile_background_color
profile_link_color
profile_text_color
profile_sidebar_fill_color
profile_background_tile

但本书作者提供的自定义JTwitter库希望API为它们返回值，当它找不到它们时，它会抛出一个org.json.JSONException，它包含在winterwell.jtwitter.TwitterException中。

我从以下网址下载了该库的来源：

https://github.com/marakana/LearningAndroidYamba/tree/master/JTwitterYamba

并通过注释掉上面列出的项目的相关行来更新库。这解决了我的问题。
