Android ProGuard error with org.xmlpull.v1.XmlPullParser

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.

add this line to proguard-project.txt

-dontwarn org.xmlpull.v1.**

and this line to project.properties

proguard.config=proguard-project.txt

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

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/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.

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.

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.

The dependency already exist on your folder,

exclude it like below:

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

  }
}

Sometimes it happens when you include one of your test libraries as a regular module dependency. For example don't do:

implementation 'com.android.support.test:runner:1.0.2' //wrong!!

do:

androidTestImplementation 'com.android.support.test:runner:1.0.2' //right (:

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
