Standard equivalent for JAXB in Android

Question

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?

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.

See some previous posts on the topic:

I'd rather try SimpleXML.

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'
}
