Can't run XML parser Jackson on Android

Question

 import android.content.Context;

import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.dataformat.xml.XmlMapper;
import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlProperty;
import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlRootElement;

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;

import java.io.IOException;
import java.net.URISyntaxException;
import java.util.List;




in onCreate(){
    ObjectMapper xmlMapper = new XmlMapper();
            Channel root = xmlMapper.readValue(stringXML, Channel.class);
}



@JacksonXmlRootElement(localName = "channel")
    public static class Channel {
        public List<Item> channel;
    }

    public static class Item {
        @JacksonXmlProperty(localName = "item")
        public String item;
    }

Error is :

java.lang.NoClassDefFoundError: Failed resolution of: Ljavax/xml/stream/XMLInputFactory;
 Caused by: java.lang.ClassNotFoundException: Didn't find class "javax.xml.stream.XMLInputFactory" on path: DexPathList

If you are asking "How to fix this error?", what is "_How to rename main Name of the project in Android Studio?_" question doing at the beginning of the post? And your code is incomplete, it won't compile. Please, create a [mcve]. — Roman, Oct 01 '15 at 15:54

Old question but...

Android doesn't have the javax.xml.stream package, which is required for most libraries involving XML.

To add this yourself, add this dependency to your build.gradle file:

compile group: 'javax.xml.stream', name: 'stax-api', version: '1.0-2'

This is the latest release as of writing this comment. You can check here for updated versions.

it's really helped, Thanks – Abror Esonaliev Dec 21 '18 at 13:18
Worked for me as well. Was very frustrating to get Jackson working without this. Used to be easier, now everything's too Oracle JRE specific. – Sandeep Aug 07 '23 at 15:57

You didn't setup Jackson for Android correctly. Look at this page Using jackson-dataformat-xml on android. There are good description how to do it.
