(Android) java.lang.NoClassDefFoundError: Failed resolution of: Ljavax/xml/stream/XMLInputFactory

I am trying to deserialise some XML and am getting the following exception.

I have these includes: implementation “com.fasterxml.jackson.module:jackson-module-kotlin:2.13.2” implementation(“com.fasterxml.jackson.dataformat:jackson-dataformat-xml:2.13.2”) implementation(“com.fasterxml.woodstox:woodstox-core:6.2.8”)

I can serialise/deserialize json fine, the issue is just with XML.

After adding implementation 'javax.xml.stream:stax-api:1.0-2' to my dependencies the following works for me:

val xmlFactory = XmlFactory.builder()
                .xmlInputFactory(WstxInputFactory()) 
                .xmlOutputFactory(WstxOutputFactory())
                .build()

Ah… that’s unfortunate but not surprising. I would take a PR against 2.14 to use the old “deprecated” method if that helps Android compatibility.
