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:

-keepclassmembers class * implements android.os.Parcelable {

}

-keepclassmembers class **.R$* {

}

after adding

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

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

Answer 1

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
