I'm trying to use ProGuard with one of my applications, let's say A. This application includes another application as a library (let's say B). This is my proguard file.

-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
-verbose
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application
-keep public class * extends android.app.Service
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider
-keep public class * extends android.app.backup.BackupAgentHelper
-keep public class * extends android.preference.Preference
-keep public class com.android.vending.licensing.ILicensingService

-keepclasseswithmembernames class * {
    native <methods>;
}

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet);
}

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet, int);
}

-keepclassmembers class * extends android.app.Activity {
   public void *(android.view.View);
}

-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

-keep class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator *;
}

-injars      bin/classes
-libraryjars lib 

When I first executed it, I got the following error:

 Proguard returned with error code 1. See console
[2012-01-05 12:18:55 - BSabadellHC-Entrega] Note: there were 1059 duplicate class     definitions.
[2012-01-05 12:18:55 - BSabadellHC-Entrega] java.io.IOException: Can't write     [/private/var/folders/19/321lw_654pzdqr8y34ysvsx80000gn/T/android_7971378611269030364.jar]     (Can't read     [/private/var/folders/19/321lw_654pzdqr8y34ysvsx80000gn/T/android_1457478862713006376.jar]     (Duplicate zip entry [com/ideaknowing/labs/android/ikarengine/e.class ==     android_1457478862713006376.jar:com/ideaknowing/labs/android/ikarengine/R$anim.class]))

The relevant parts for me are:

  • There are duplicate objects
  • They should because of the R files. It is said by the console that there are duplicate resources in R$anim (of course, since both the application A and the library B are including animations, layouts and so on).

So my idea was obviously to exclude from ProGuard the R files, and for that I included the following lines of code:

-keep public class net.firsrproject.android.R
-keep public class com.ideaknowing.labs.android.ikarengine.R 

Nevertheless, I still get the same error (so I guess the files are still being included in Proguard). Has anybody experience with removing R files from ProGuard? Is there any tip or suggestion on how can I get rid of this error?

Thanks, and regards

Remove the -injars bin/classes if you are using android library project as the class files from the library are processed twice with this option (This worked for me in combination with this).

If the above doesn't work try the -dontnote option.
