Unable to call server side methods in apk package

help
1

This is my server method

  Registration:function(data,reader){
  var result;
  console.log('in server',(reader)); 
  if(data){
    console.log(JSON.stringify(data))
        conn.sobject("Contact").create(data, function(err, ret) {
         if (err || !ret.success) { result=err;return err; }

          console.log("Created record id : " + ret.id);

      
   })

 }

this is my client side code

  Template.JobSeekerRegTemplatePhone2.events({


'click  #JobSeekerSignUp': function (e) {
     var JobSeekerData={};
           JobSeekerData['FirstName']='test';
           JobSeekerData['LastName']='test';
         var filedata={};
       filedata['ContentType']='application/json';
       filedata['Name']='Resume';


  Meteor.call('Registration', JobSeekerData,filedata,function(error, result){
           if(error){
           alert('Error');
           }else{
            alert('success',result);
             Router.go('/JobSeekerRegTemplatePhone3');
             Session.set("data", result)
          }
  });
        
}
});

This code is working fine in Desktop and when I am using “meteor run android-device” command.

but when I am generating the apk file and test this .it is not sending data to the salesforce org and I am not getting any result in the callback function.

I have tried 2 ways to generate the apk
meteor build ~/Desktop --server=Appname --debug
meteor build ~/Desktop --server=Appname.meteor.com --debug

Please help …
