How to use Proguard with Android Annotations?

Does anybody know how to use Proguard with Android Annotations?
I found this resource:
https://code.google.com/p/androidannotations/wiki/ProGuard
But when I use the proguard.cfg file from there, I get the following error:
proguard.ParseException: Unknown option '*' in line 6 of file
'/Users/jabdulius/Documents/Dropbox/workspace-tinder/Tinder/proguard.cfg'
Here's the proguard.cfg file I copied from the link:
-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>;
}
-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 *;
}

When you copy and paste from the website, you may notice your paste includes spaces before the asterisks that were not present in the original (a minor formatting error).. simply remove the two spaces, changing the following line:
-optimizations !code/simplification/arithmetic,!field/ *,!class/merging/ *
to match this:
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*
You'll also note, as Eric has said (and he would know best!!) the newer versions of ADT include a default proguard configuration referenced in new project.properties:
#proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt
Uncommenting the line (remove the #)will load the default properties (proguard-android.txt) and then override it with any changes you make in your project proguard-project.txt.
Those default properties include many of the rules that Android Annotations project recommends, and are sufficient for most basic apps.

As of Android SDK r20, the ProGuard configuration file is called proguard-project.txt, and it can be empty to start with. It only needs to contain project-specific settings. Try upgrading your SDK and your project.

Android: proguard is not obfuscating the source

I have enabled proguard in project.properties:
proguard.config=proguard.cfg
My proguard.cfg does not disable obfuscation. But nothing is obfuscated.
I run the project build with
ant release.
Any bells ringing?

-keepclassmembers enum * {
public static *[] values();
public static * valueOf(java.lang.String); }
-keep class * implements android.os.Parcelable { public static final android.os.Parcelable$Creator *; }

You should make sure that your project is configured for your Android SDK:
android update project -p MyProjectDirectory
As of Android SDK r20, the ProGuard configuration file is split into several parts, which are specified in project.properties:
proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt
The short project-specific configuration is defined in proguard-project.txt (no longer in proguard.cfg, like it was in older versions of the SDK). The SDK documentation may not be entirely up to date in this respect.
When you run ant release, you should see some logging output from ProGuard.

#Thanks Danail, Today i just overcome from this problem .Just elaborating
android:debuggable
Whether or not the application can be debugged, even when running on a device in user mode — "true" if it can be, and "false" if not. The default value is "false".
For more details you can visit
http://www.vogella.com/tutorials/AndroidDebugging/article.html

It was way more trivial than what I thought: we had (in our manifest.xml file) enabled the
android:debuggable="true"
Doh.

Ant seems to ignore jar generated by Proguard while packaging apk

I have a Jenkins build server for building Android APKs with ant and Android (SDK Revision 18). Releasing APKs is working fine. However if i enable proguard by providing a proguard.cfg and pointing to it by "proguard.config=proguard.cfg" in the project.properties the following seems to happen:
Proguard is executed (as seen from shell output and the existence of mappings.txt and seeds.txt afterwards)
an apk is generated. However the Stacktraces generated by the APK are not obfuscated at all.
Anybody got an idee on this? It seems that the jar generated by proguard is for some reasons not included in the apk.
Here is my Proguard Config

}
#ACRA specifics

# ACRA needs "annotations" so add this...
-keepattributes *Annotation*
# keep this class so that logging will show 'ACRA' and not a obfuscated name like 'a'.
# Note: if you are removing log messages elsewhere in this file then this isn't necessary
-keep class org.acra.ACRA {

}
# keep this around for some enums that ACRA needs
-keep class org.acra.ReportingInteractionMode {

}
# keep this otherwise it is removed by ProGuard
-keep public class org.acra.ErrorReporter

}
# keep this otherwise it is removed by ProGuard
-keep public class org.acra.ErrorReporter
{
public org.acra.ErrorReporter$ReportsSenderWorker handleSilentException(java.lang.Throwable);
}
The mappings.txt states that my code is obfuscated:
de.cellular.crashtest.ObfuscateThisClass -> de.cellular.crashtest.b:
However it is not obfuscated in the reported Stacktrace

It seems it was just a jenkins configuration problem: the apk was archived from the bin/ directory but the obfuscated one was in release/

Getting java.lang ExceptionInInitializerError when initializing ACRA

I integrated ACRA to my application to get crash reports from my app in beta stadium so I'm able to fix bugs, find errors in code, etc. If I run this on the emulator everything works fine and ACRA is up and running, but if I export a signed package of my application with Android Tools I get an ExceptionInInitializeError and the application is force closed on the device. If I catch this Error and proceed without ACRA the app itself runs like a charm...
has anybody here got the same issue with ACRA? could it be that it has something to do with ProGuard? I followed the ProGuard how to on ACRA homepage but perhaps I'm missing something on this?
here's what my proguard.cfg looks like:
-injars 'C:\Workspaces\motodevWs\gp2012\bin\classes'
-injars 'C:\Workspaces\motodevWs\gp2012\libs'
-outjars 'C:\Workspaces\motodevWs\gp2012\bin\classes-processed.jar'

PROBLEM SOLVED!
After some effort on research and rethinking my problem I found the solution to the problem and it was indeed in my proguard.cfg file where I missed something!
somehow I managed not to keep enums, now I added
-keepclassmembers enum * {
public static **[] values();
public static ** valueOf(java.lang.String);
}
to my proguard.cfg and everything is working perfectly!!

So, to close this question with the answer I found myself, here is what I did to resolve this particular problem :) (taken from my question post):

Proguard Android App for LVL and Fragment Compatibility Support

I'm trying to use Proguard against my app which will eventually incorporate LVL and In-app Billing. The problem I have is that Proguard keeps crashing my app on start and it's hard to figure out what's failing.
I'm using the Android V4 support compatibility library and it seems to be blowing away that library as well as some other stuff.
Does anyone has a proguard.cfg that works with a basic version of the v4 compat library for starters?
Currently I'm using the stock proguard.cfg which doesn't work.

-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 * {

-keepclasseswithmembernames class * {

-keepclasseswithmembernames class * {

}
-keepclassmembers enum * {
public static **[] values();
public static ** valueOf(java.lang.String);
}
-keep class * implements android.os.Parcelable {
public static final android.os.Parcelable$Creator *;
}

That's not enough to produce a working application.. proguard will for example delete all your fragments by default, and there are some more compat. libraries it uses.
I've found the following works:
-dontwarn **CompatHoneycomb
-dontwarn **CompatHoneycombMR2
-dontwarn **CompatCreatorHoneycombMR2
-keep class android.support.v4.** { *; }
-keep public class * extends android.support.v4.**
-keep public class * extends android.app.Fragment
In theory if you simply want proguard as an obfuscator and are not ineterested in its other 'features', then
-dontshrink
-dontoptimize
Should switch it off. Even with that, though test thoroughly on a real android 1.6 phone. I didn't and found too late proguard had made a breaking change to the binary that only manifested on 1.6...

To have Proguard working with v4 compatibility library add this to your proguard.cfg:
-dontwarn **CompatHoneycomb
-keep class android.support.v4.** { *; }
