Standard equivalent for JAXB in Android

I am building an APP that uses XML requests and responses to communicate with a server via HTTP POST. Due to copyright restriction I cannot use SIMPLE XML to do (at least partially) what JAXB would normally do, and from all the information I have JAXB cannot be used on Android.

I did the job using XmlSerializer to build the request and XMLPullParser for parsing the response but I don`t like how the code looks like and I was not able to find any standard equivalent for JAXB in the Android SDK.

Is there any SDK component that I can use to transform the XSD schema files to Java classes and then use marshaller/unmarshaller to/from a XML file or I am stuck with using XmlSerializer/XMLPullParser?

I had the same question -- and figured it out. Using jackson-module-jaxb-annotations and XmlToJson :

public static String jaxbObjectToXML(SomeClass object)
    {
        JaxbAnnotationModule module = new JaxbAnnotationModule();
        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.registerModule(module);

        try {
            JsonToXml jsonToXml = new JsonToXml.Builder(
                    objectMapper.writeValueAsString(object)).build();
            return jsonToXml.toString();
        }catch (JsonProcessingException e) {
            e.printStackTrace();
        }

        return null;
    }

Dependencies:

dependencies {
    ...
    implementation group: 'javax.xml.bind', name: 'jaxb-api', version: '2.3.1'
    implementation 'com.fasterxml.jackson.module:jackson-module-jaxb-annotations:2.4.0'
    implementation 'com.github.smart-fun:XmlToJson:1.5.1'
}

See some previous posts on the topic:

I'd rather try SimpleXML.

No.

I am stuck with using XmlSerializer/XMLPullParser?

You are welcome to use DOM or SAX instead of XmlPullParser, just as you can in classic Java.

There are also several XML parsing libraries for Android, beyond just SimpleXML.
