java - Android Proguard - 一步一步

Question

我第一次尝试在我的 Android 项目上使用 ProGuard。

我有几个问题:

1. 对于/libs 文件夹中的 jar 文件，应如何在 proguard-project.txt 中引用它们？

   • -injars/libs/commons-lang3-3.1.jar
   • 或
   • -libraryjars/libs/commons-lang3-3.1.jar
   • ？

2. 对于我工作区中的库项目，我是否必须在 proguard-project.txt 中写下一些内容？

3. 我收到很多这样的警告:

这是怎么回事？ XmlPullParser 是 Android 框架的一部分，对吗？怎么会少呢？

[2013-08-12 14:27:13 - bauen.de]          Your input classes appear to be inconsistent.
[2013-08-12 14:27:13 - bauen.de]          You may need to recompile them and try again.
[2013-08-12 14:27:13 - bauen.de]          Alternatively, you may have to specify the option 
[2013-08-12 14:27:13 - bauen.de]          '-dontskipnonpubliclibraryclassmembers'.

我真的应该设置-dontskipnonpubliclibraryclassmembers吗？

proguard-project.txt 中的设置是否有一定的顺序？

您的一个库包含 org.xmlpull.v1 类的副本，即使这些类已存在于 Android 运行时中。您应该从库中删除这些类。无论如何，Android 运行时中的版本都会优先。
