使用proguard后在.jar中出现InvalidClassCastException

Question

我正在使用eclipse开发一个android应用程序。当我按下运行(绿色三角形)时，该应用程序工作正常。但是，我启用了proguard，程序崩溃了。我使用默认的proguard-android.txt，它存在于sdk/tools/proguard中。

我有一个名为Software.jar的jar，其中有几个类。其中之一(Data)是一个可序列化的类。(with serialversionUID=112358L)。这(可能)是导致错误的部分。

这是错误日志(我不知道为什么，但它显示为黄色作为警告):

有趣的是，我有一个系统。在software.jar的一个类中。这是打印出来的。

我试过添加-libraryjars C:UsersHarshgitmarks++Marks++Software.jar以及

-keep  class Software.**

到前面提到的。txt文件

我哪里错了?

Answer 1

似乎在经历了proguard之后，你的serializable类的serialVersionUID正在改变。您需要更改configuration of proguard以包含:

-keepclassmembers class software.Data {
static final long serialVersionUID;
}

如下所述

Answer 2

经过一些试验，我找到了一个可行的解决方案。这是我使用的:

-libraryjars Software.jar
-keep  class software.**{
*;
}
