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?

Apparently, org.xmlpull.v1.XmlPullParser is not a program class. I've updated ProGuard to newest version(4.6), but have same warnings.

Answer 1

add this line to proguard-project.txt

-dontwarn org.xmlpull.v1.**

and this line to project.properties

proguard.config=proguard-project.txt

Answer 2

I solved this using this settings in the proguard file:

-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
