Android ProGuard error with org.xmlpull.v1.XmlPull

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?

[2011-03-17 09:27:04 - MyProject] Proguard returned with error code 1. See console

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

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

Answer 2

for me I could solve it by removing my previous modified build.gradle

I removed:

     minifyEnabled true

     shrinkResources true

and returned to the original setting

minifyEnabled false

Answer 3

I think your jar package include XmlPullParser class, and android.jar also include this. So you can remove org.xmlpull.* classes in the jar package, and build again.

Answer 4

The dependency already exist on your folder,

exclude it like below:

dependencies {
  configurations {
      all*.exclude group: 'xmlpull', module: 'xmlpull'

  }
}

Answer 5

I don't have the solution yet for proguard run via eclipse for android, but if you run proguard manually from the command line, you can put the following in your proguard.cfg:

-basedirectory /home/pjv/workspace/collectionista-repo/collectionista-main

-injars /tmp/android_4500371803543847111.jar
-injars libs/joda-time-1.6.jar(!META-INF/MANIFEST.MF)
-injars libs/FlurryAgent.jar(!META-INF/MANIFEST.MF)
-injars libs/veecheck-2.0.jar(!META-INF/MANIFEST.MF)
-injars libs/commons-lang-2.4.jar(!META-INF/MANIFEST.MF,!META-INF/NOTICE.txt,!META-INF/LICENSE.txt)
-injars libs/OIAbout-lib-temporary.jar(!META-INF/MANIFEST.MF)
-injars libs/libGoogleAnalytics.jar(!META-INF/MANIFEST.MF)
-injars libs/xstream-1.3.1.jar(!META-INF/MANIFEST.MF)
-injars libs/ZQL_custom.jar(!META-INF/MANIFEST.MF)
-injars libs/xpp3_min-1.1.4c.jar(!META-INF/MANIFEST.MF)
-injars libs/GoogleAdMobAdsSdk-4.1.0.jar(!META-INF/MANIFEST.MF)
-injars libs/bugsense-trace.jar(!META-INF/MANIFEST.MF)
-outjars /tmp/android_1348923171424559204.jar

-libraryjars /opt/android-sdk/android-sdk-linux_x86-1.6_r1/platforms/android-12/android.jar(!org/xmlpull/v1/XmlPullParser.class,!org/xmlpull/v1/XmlPullParserException.class)

Note how XmlPullParser.class is filtered from the android API jar.

Don't worry about the warnings related to XmlPullParser just yet. Fix the errors and other warnings first, and if you must, use -ignorewarnings in your proguard.cfg.

add this line to proguard-project.txt

-dontwarn org.xmlpull.v1.**

and this line to project.properties

proguard.config=proguard-project.txt
