java - Error when trying to implement amazon mturk SDK into android studio project -

-

i trying implement amazon's mechanical turk android app. have followed instructions: http://docs.aws.amazon.com/awsmechturk/latest/awsmechanicalturkgettingstartedguide/creatingahit.html#java when specifying third party .jar files, gives me

error:gradle: execution failed task ':app:dexdebug'.

com.android.ide.common.process.processexception: org.gradle.process.internal.execexception: process 'command '/library/java/javavirtualmachines/jdk1.7.0_79.jdk/contents/home/bin/java'' finished non-zero exit value 1

i have tried taking out every combination of .jar files , found out jaxrpc.jar file causing error. without file, error when running project is:

exception in thread "main" java.lang.noclassdeffounderror: javax/xml/rpc/serviceexception     @ com.example.mturk.homeworkrequest.<init>(homeworkrequest.java:20)     @ com.example.mturk.homeworkrequest.main(homeworkrequest.java:39)     @ sun.reflect.nativemethodaccessorimpl.invoke0(native method)     @ ...

where line 20 points to: 

service = new requesterservice(new propertiesclientconfig("../mturk.properties"));

and line 39 points to:

homeworkrequest app = new homeworkrequest();

i have tried enabling multidex , looked around couldn't find solution. appreciated, have been stuck on problem few days now.

edit: here's code far. it's simple hit request similar sample in http://docs.aws.amazon.com/awsmechturk/latest/awsmechanicalturkgettingstartedguide/creatingahit.html#java

import com.amazonaws.mturk.requester.hit; import com.amazonaws.mturk.service.axis.requesterservice; import com.amazonaws.mturk.service.exception.serviceexception; import com.amazonaws.mturk.util.propertiesclientconfig;  public class homeworkrequest{  private requesterservice service; private string title= "math question"; private string description = "solve math question shown"; private int numassignments = 3; private double reward = 0.05;  public homeworkrequest(){     service = new requesterservice(new propertiesclientconfig("../mturk.properties")); }  public void createhomeworkrequest(){     try {         hit hit = service.createhit(                 title, description, reward, requesterservice.getbasicfreetextquestion(                         "can solve math question?"), numassignments);          system.out.println("created hit: " + hit.gethitid());         system.out.println("hit location: ");         system.out.println(service.getwebsiteurl() + "/mturk/preview?groupid=" + hit.gethittypeid());     }     catch(serviceexception e) {         system.err.println(e.getlocalizedmessage());     } }  public static void main(string[] args){     homeworkrequest app = new homeworkrequest();     app.createhomeworkrequest(); } }

if @ step 1 of using mturk java sdk, need include sdk installation directory]\lib\third-party in classpath.

your inability find third-party jars such jaxb seems suggest ide facing issues finding necessary jars build.

please let know if still facing difficulties.
