proguard

I am trying to use proguard in an android application which uses a android library project and I am getting the following error : java.io.IOException: Can't write [/private/var/folders/Pg/PgUpPJQ-E5qxL7jX6kpdCE+++TI/-Tmp-/android_3140050575281008652.jar] (Can't read [proguard.ClassPathEntry@1f8d244] (Duplicate zip entry [be.class == android_144638064543155619.jar:com/comp/dp/library/R$anim.class])) at proguard.OutputWriter.writeOutput(OutputWriter.java:224) at proguard.OutputWriter.execute(OutputWriter.java:120) at proguard.ProGuard.writeOutput(ProGuard.java:391) at proguard.ProGuard.execute

I am doing first time proguard setting on My Android Project and Exporting My APK File but I got Following errors: (I also not found any proguard.cfg file in my project root) [2013-08-01 10:54:42 - SalesmanTracker] Note: there were 2 duplicate class definitions.

I have applied ProGuard to my Android application. I'm using android-studio/sdk/tools/proguard/proguard-android.txt as a configuration file, changing nothing. In this file I can see the only statement regarding Activity : We want to keep methods in Activity that could be used in the XML attribute onClick -keepclassmembers class * extends android.app.Activity { public void *(android.view.View); } It follows from that the Activities class names are obfusctated by ProGuard while some methods are preserved as they are. This is understandable. However, in my application I then create an Activity

I am using Jackson JSON Processor for my app.Included this using compile 'com.fasterxml.jackson.core:jackson-databind:2.4.2' compile 'com.fasterxml.jackson.core:jackson-annotations:2.4.2'. And my proguard configuration is. ## BEGIN -- Google Play Services proguard.txt -keep class * extends java.util.ListResourceBundle { protected java.lang.Object[][] getContents(); } # Keep SafeParcelable value, needed for reflection. This is required to support backwards # compatibility of some classes. -keep public class com.google.android.gms.common.internal.safeparcel.SafeParcelable { public static final *

I'm using the v7 Support Library to show an ActionBar on Android 2.x. It works well enough but I had to fix a few class/method not found errors after enabling Proguard. Are there any guidelines on which classes need to be preserved? So far I have these: -keep public class android.support.v7.internal.widget.ActionBarContainer -keep class android.support.v7.internal.widget.ActionBarView$HomeView -keep public class android.support.v7.internal.widget.ActionBarContextView It seems to work now but I'm not that confident that it won't crash at some stage because of some other supposedly internal

I am trying to use javamail in my Android app, but proguard complains about a whole load of stuff that it cannot find. I have tried various remedies that I have found while searching the internet, but nothing seems to work. Has anyone got this thing working? Thanks. I have added some -dontwarn commands to the defauly proguard.cfg, and succeeded in eliminating all of the warning messages except this one: Warning: org.apache.harmony.awt.datatransfer.DataProxy: can't find referenced class [Ljava.awt.datatransfer.DataFlavor; This warning is not even in the same format as all the others. I am using

Update: This problem is fixed in new versions of Samsung's SPen SDK. I am trying to create a signed APK with Eclipse 3.7.1, running Proguard 4.7 as part of the process. However, I am unable to run Proguard on projects which include Samsung's SPen SDK 1.5 and get the following errors: [2012-01-16 14:16:45 - SDraw_Example1] Proguard returned with error code 1.
