android - Proguard 4.7 与 Eclipse SDK 3.7.1 : Proguard fails with java. io.IOException -(堆栈映射框架中的未知验证类型 [25])

Question

更新:此问题已在三星 SPen SDK 的新版本中修复。

我正在尝试使用 Eclipse 3.7.1 创建签名的 APK，并在此过程中运行 Proguard 4.7。但是，我无法在包含三星 SPen SDK 1.5 的项目上运行 Proguard，并出现以下错误:

Java 7 报告了类似的问题，但我的 Java 编译器合规级别设置为 1.6，并且我在“已安装的 JRE”中检查了 jre6。

您可以在 Samsung Mobile 的网站上获取重现问题的源代码: http://innovator.samsungmobile.com/down/cnts/toolSDK.detail.view.do?platformId=1&cntsId=10210

我正在尝试导出包含在上述 Zip 文件中的示例项目 SDraw_Example1。

关于可能导致问题的原因以及如何解决它的任何想法？谢谢!

问题是由附加到 SPen 库 (libspen.jar) 中方法的损坏的预验证信息(StackMapTable 属性)引起的。该库似乎已使用 ProGuard 本身进行了处理，但可能预验证配置错误，或者其他工具随后破坏了预验证信息。您可以修改 ProGuard 以忽略该属性，甚至再次预验证库。我会在 your thread 中通知三星在他们的开发者论坛上。
