org.xmlpull.v1.XmlPullParser出现Android ProGuard错误

Question

当我的应用程序使用ProGuard构建时,它会失败并显示以下消息.我使用Android SDK生成的默认proguard.cfg和一些-libraryjars.我能做些什么？

显然,org.xmlpull.v1.XmlPullParser不是程序类.我已将ProGuard更新到最新版本(4.6),但有相同的警告.

Answer 1

将此行添加到proguard-project.txt

-dontwarn org.xmlpull.v1.**

这行到project.properties

proguard.config=proguard-project.txt

Answer 2

我使用proguard文件中的这个设置解决了这个问题:

-dontwarn org.kobjects.**
-dontwarn org.ksoap2.**
-dontwarn org.kxml2.**
-dontwarn org.xmlpull.v1.**

-keep class org.kobjects.** { *; }
-keep class org.ksoap2.** { *; }
-keep class org.kxml2.** { *; }
-keep class org.xmlpull.** { *; }

-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontoptimize
-dontpreverify

Answer 3

根据您提供的部分日志，Android运行时类org.xmlpull.v1.XmlPullParser已最终出现在您的程序代码中。您应该确保它不存在于bin/classes或lib中的某些 jar 中，因为它已经存在于库 jar android.jar 中。

此外，您还有 4247 个重复的类定义。这可能是由于指定了您提到的“some -libraryjars”。我猜这些库 jar 已经由构建脚本自动包含，所以您不应该再次指定它们。
