Proguard Aws s3 issue

Question

Having a real issue trying to implement proguard for amazon s3 it keeps on crashing on loading the application at line 29 which is

  s3Client = new AmazonS3Client(new BasicAWSCredentials(
            Constants.ACCESS_KEY_ID, Constants.SECRET_KEY));

This is the stack trace of the error and not sure what it means to be honest any way getting a better stacktrace or any suggestions on how to fix it?

sorry that you're having trouble. It looks like you haven't tried using the Proguard config provided in the AWS samples. It might still not fix your problem, but it would be worthwhile to give it a try. If it still doesn't work we can try seeing where to go from there, and at least it would likely give you a better stack trace. You can find it here: https://github.com/awslabs/aws-sdk-android-samples

And the proguard config is..

# These options are the minimal options for a functioning application
# using Proguard and the AWS SDK for Android

-keep class org.apache.commons.logging.**               { *; }
-keep class com.amazonaws.services.sqs.QueueUrlHandler  { *; }
-keep class com.amazonaws.javax.xml.transform.sax.*     { public *; }
-keep class com.amazonaws.javax.xml.stream.**           { *; }
-keep class com.amazonaws.services.**.model.*Exception* { *; }
-keep class com.amazonaws.internal.**                                   { *; }
-keep class org.codehaus.**                             { *; }
-keep class org.joda.time.tz.Provider                    { *; }
-keep class org.joda.time.tz.NameProvider                { *; }
-keepattributes Signature,*Annotation*,EnclosingMethod
-keepnames class com.fasterxml.jackson.** { *; }
-keepnames class com.amazonaws.** { *; }

-dontwarn com.fasterxml.jackson.databind.**
-dontwarn javax.xml.stream.events.**
-dontwarn org.codehaus.jackson.**
-dontwarn org.apache.commons.logging.impl.**
-dontwarn org.apache.http.conn.scheme.**
-dontwarn org.apache.http.annotation.**
-dontwarn org.ietf.jgss.**
-dontwarn org.joda.convert.**
-dontwarn org.w3c.dom.bootstrap.**

#SDK split into multiple jars so certain classes may be referenced but not used
-dontwarn com.amazonaws.services.s3.**
-dontwarn com.amazonaws.services.sqs.**

-dontnote com.amazonaws.services.sqs.QueueUrlHandler

Please let me know if it still gives you trouble after using this.
