当谈到 android 开发时，我有点菜鸟，所以所有的帮助都将不胜感激。
我正在尝试在我正在开发的 rss 应用程序中查看来自多个来源的提要。目前我只有一个“提要”硬编码到源代码中。
我想我可以通过将我想要的所有来源的列表存储在资产文件夹中的文本文件中并让应用程序使用该列表来获取提要来接近它。我基本上在弄清楚如何实现编码方面遇到了问题，因为我对 android 编码不是很好。主要原因是现在我需要成为一个证明应用程序可以与源通信以获取和检索数据的原因，而且因为未来的发展将需要用户能够手动添加源，所以我认为它们可以被编写到文本文件并从中检索
如果有更简单或更直接的方法来解决这个问题，我会欢迎任何建议。
谢谢
编辑在下面对我的代码进行了一些更改，但仍然无法运行，但使用调试器我可以看出它实际上读取了文件，问题似乎出在String[] RssLinksArray = readLine.split("[\\;]+");代码终止的地方，我终生无法弄清楚为什么。我也附上了logcat。
任何帮助将不胜感激。
