I am kind of stuck from past 1 week from this issue. I am trying to export my android app for final release but it gives following errror while exporting.

Proguard returned with error code 1. See console

I am able to export my .apk file successfully from eclipse if I am using below content in my proguard-project.txt file. BUT when I am installing and running that app in device , it is crashing.

-dontwarn android.support.v4.**

-dontwarn javax.activation.**

-dontwarn javax.security.**

-dontwarn java.awt.**

perhaps some support v4 class or interface was confounded, i tried this and it works -dontwarn android.support.v4.** -keep class android.support.v4.** { *; } -keep interface android.support.v4.app.** { *; } -keep public class * extends android.support.v4.** -keep public class * extends android.app.Fragment
