Question

Hello I’m writing an application that uses the compatibility library and i’m using a view pager in the app. I also am using an action bar library which i got from this link

https://github.com/johannilsson/android-actionbar

my proguard.cfg file looks like this

-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

#keep all classes that might be used in XML layouts
-keep public class * extends android.view.View
-keep public class * extends android.app.Fragment
-keep public class * extends android.support.v4.Fragment


#keep all public and protected methods that could be used by java reflection
-keepclassmembernames class * {
    public protected <methods>;
}

-keepclasseswithmembernames class * {
    native <methods>;
}

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

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


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

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

-dontwarn **CompatHoneycomb
-dontwarn org.htmlcleaner.*

and then my defualt.properties looks like this

target=android-8
android.library.reference.1=../android-actionbar/actionbar
proguard.config=proguard.cfg

However when i run to compile and sign my app i get a dialog that reads “Proguard returned with error code 1. See console.”

So i take a look at my console which reads the following

[2011-11-01 01:48:39 - Test App] Proguard returned with error code 1. See console
[2011-11-01 01:48:39 - Test App] proguard.ParseException: Unknown option 'Manager' in argument number 9

[2011-11-01 01:48:39 - Test App]    at proguard.ProGuard.main(ProGuard.java:491)

But this doesn’t really mean much to me and i don’t know what i’m supposed to do to get this working? Any ideas i’ve used that proguard script before on an app that didn’t use the compatibility library, however, the place i got that script from says it should work with the compatibility library but its not? Anyone have any ideas it would be greatly appreciated

===EDIT===

After removing the spaces from my build path i was able to get a bit farther but still failed with error 1 the console now had a new list of errors which looks like this now.

[2011-11-01 14:01:20 - TestApp] Proguard returned with error code 1. See console

Answer 1

I’m guessing your project path contains spaces (and in this case the word Manager). The latest Android plugin for Eclipse (ADT R14) still has problems passing paths containing spaces to ProGuard. Alternative work-arounds:

• Use the command-line build based on Ant. The problem should be solved there.
• Install ProGuard 4.7 beta2 (or later). It is more lenient for missing quotes around file names containing spaces. You can just download the release and copy the jars from proguard/lib to android-sdk/tools/proguard/lib.
• Use a project path without spaces.
