Proguard runtime error with external Admob jar

Question

signed app gives error!

my app uses an external Admob jar, however proguard is touching the jar:

the jar file is located at /libs/GoogleAdMobAdsSdk-6.2.1.jar

Thank you

LogCat error:

Proguard returned with error code 1. See console

which is inside the jar-file

Config proguard-project.txt:

-libraryjars /libs/GoogleAdMobAdsSdk-6.2.1.jar

-dontpreverify

}

-keepclassmembers class * implements android.os.Parcelable {

}

-keepclassmembers class **.R$* {
public static <fields>;
}

after adding

-keep public class com.google.ads.**

to the file, the eclipse console gives still the following error:

Thanks for the comment. But this does not work for the e.g. Dropbox Sdkor other external jars. These will be touched or altered by the proguard — user1616685, Nov 02 '12 at 09:20
Sounds like you don't want proguard to alter the library files. You should add `-keep public class com.google.ads.**` for the AdMob SDK jar, and something similar for the other jars, so these classes don't get renamed. — Eric Leichtenschlag, Nov 02 '12 at 16:55

I just added the

-dontwarn com.google.ads.**

to the proguard-project.txt file and the signed apk works fine! this is recommended (like Eric said before) here: Proguard can't find referenced class com.google.ads.internal.state.AdState

This worked for me on It seems that you need to add these 2 items to the proguard config :

-dontwarn com.google.ads.**
-keep class com.google.ads.**  {*;}
