Proguard和Android :(

Question

我正在尝试在我的Android应用上运行Proguard并遇到问题。

我正在使用SpongyCastle jar（复制和过去的完整充气城堡，包重命名，所以它不与版本中建造的机器人充气城堡冲突）

运行proguard时，我看到以下内容

我该如何解决这个问题？将rt.jar添加到我的库中？

proguard的重点是缩小代码，但我不断添加jar来解决这些问题，其中proguard抱怨它无法找到一个类！我错过了什么吗？

UILD FAILED

更新

ANT Script

我使用android update project --path .生成build.xml，因为项目是在前一段时间创建的，我没有做任何更改

<?xml version="1.0" encoding="UTF-8"?>
    <project name="RootActivity" default="help">
        <loadproperties srcFile="local.properties" />
        <property file="ant.properties" />
        <loadproperties srcFile="project.properties" />
        <fail message="sdk.dir is missing. Make sure to generate local.properties using 'android update project'" unless="sdk.dir" />
        <import file="${sdk.dir}/tools/ant/build.xml" />
    </project>

Answer 1

将以下-dontwarn javax.naming.**添加到您的Proguard配置中。

它们只是警告，忽略它们应该不是问题。

Answer 2

我认为不需要将rt.jar添加到您的libs中。您需要确保在proguard脚本中正确引用它。看看here的例子。第2节中的这一行是赚钱者：

-libraryjars ${java.home}/lib/rt.jar

但是，如果对proguard使用xml表示法，则语法会发生变化。如果您发布负责的蚂蚁脚本部分，我可以尝试提供更多帮助。希望这有帮助！
