I am having an error with the Proguard file in Android.
The point is, I know how to use it in an Android Project, but now, I need to use it for an Android Library Project, and the .jar extracted (there is no resources on the library), to obfuscate the code, because I would like to distribute my library for everyone to use it, but with the code obfuscated.
My Android library project is a normal one, I just take the .jar with is contained in the "bin" folder from the Library Project, and I am trying to use the Proguard to obfuscate it this way:
java -jar proguard.jar @proguard-project -verbose
My Proguard file is the next one:
-injars in.jar -outjars out.jar
-libraryjars /home/jorider/wul4/adt-android/sdk/platforms/android-17/android.jar -libraryjars /home/jorider/wul4/adt-android/sdk/extras/android/support/v4/android-support-v4.jar -libraryjars commons-codec-repackaged-3.1-b36.jar -libraryjars httpmime-4.2.5.jar
-dontusemixedcaseclassnames -dontskipnonpubliclibraryclasses -verbose
-dontoptimize -dontpreverify
-keepattributes Annotation -keep public class com.google.vending.licensing.ILicensingService -keep public class com.android.vending.licensing.ILicensingService
-keepclasseswithmembernames class * { native ; }
-keepclassmembers public class * extends android.view.View { void set*(*); get(); }
-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$Creator *; }
-keepclassmembers class *.R$ { public static ; }
-dontwarn android.support.**
The result I get for running that on the console is :
Shrinking...
java.io.IOException: The output jar is empty. Did you specify the proper '-keep' options?
Anyone knows why?
Thanks a lot!
