Android ProGuard error with org.xmlpull.v1.XmlPullParser

Question

When my application is build with ProGuard, it fails with following message. I use a default proguard.cfg generated by Android SDK with some -libraryjars. What can I do for it?<

Answer 1

According to the partial log that you provide, the Android runtime class org.xmlpull.v1.XmlPullParser has ended up in your program code. You should make sure it is not present in bin/classes or in some jar in lib, because it is already present in the library jar android.jar.

Furthermore, you have 4247 duplicate class definitions. This is probably due to specifying "some -libraryjars" as you mention. I'm guessing these library jars are already included automatically by the build script, so you shouldn't specify them again.
