how can I do no proguard to a jar in android

I include a jar to my project. I put the jar in libs folder. Then I add to build path. I run the project on my device, it runs fine. But when I signed it, it runs crash. I guess it was the proguard.

If I don't wannna progurad the very jar, How can I write the proguard-project.txt?

the jar is amazon mobile ad jar. https://developer.amazon.com/sdk/mobileads.html

this FC only happen when it's signed. So I guess it's the proguard problem. cause by part is in the amazon ad jar.

I put a lot of keep in proguard-project.txt :

-dontoptimize

-keep class com.amazon.device.ads.** { *; }

-dontwarn com.amazon.**
-keep class com.amazon.** {*;}
-keepattributes *Annotation*

-keepclassmembers class com.amazon.** {*;}
-keepclassmembernames class com.amazon.** {*;}

-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); 
 }

Solution

You can customize proguard running. I dont know well, but I remember like this.

Some Samples: http://proguard.sourceforge.net/index.html#manual/examples.html

Example:

-injars       myapplication.jar
-outjars      myapplication_out.jar
-libraryjars  <java.home>/lib/rt.jar
-printmapping myapplication.map

-keep public class mypackage.MyMain {
    public static void main(java.lang.String[]);
}
