使用Google Guava和Android 1.6

Question

我在Android应用程序中使用Guava r09库但是当我使用1.6时遇到以下错误.这有点奇怪,因为它在1.5中运行良好.此外,"未找到"的方法非常清楚.我也试过包含jsr305.jar文件,但这仍然无效.

感谢任何帮助,没有番石榴,在Java中进行I/O是如此痛苦.

这是代码:

String timestamp = CharStreams.toString(
    CharStreams.newReaderSupplier(timestampFile, Charset.forName("UTF-8")));

这是例外:

Answer 1

我设法最终解决了这个问题.如果我使用jarjar将com.google.common.io.LineReader重命名为另一个软件包名称(例如com.triposo.vendor.com.google.common.io.LineReader),它就可以了!我的猜测是LineReader捆绑在Android中,但版本略有不同(不兼容).
