Android - 使用 Joda Time 时无法使用 Proguard 导出 apk

Question

我在我的应用程序中使用 joda-time.jar，并且在导出签名的 apk proguard 时说了类似的话(当我查看互联网时，这是一个很常见的问题):

[2014-01-07 12:44:53 - XYZ] Proguard returned with error code 1. See console

在论坛的任何地方或这里 ( Android - Proguard didn't compile with Joda Time jar file )，他们说解决方案应该是下载 joda-convert.jar，添加到构建路径。但对我来说它只是行不通，在我这样做之后，proguard 再次说了类似的话:

[2014-01-07 12:41:39 - XYZ] Proguard returned with error code 1. See console

如何解决这个问题？我花了几个小时尝试了所有方法，但就是找不到答案...非常感谢!

Answer 1

好吧，我明白了。实际上将 joda-convert.jar 添加到构建路径中是可行的，但仅适用于旧版本(1.4 及更低版本，如果您下载最新版本 - 1.5 joda-convert.jar，它不起作用)...
