Set strict to false within the Root annotation to ignore any XML elements or attributes that do not appear in the class. @Root(strict=false) Alternatively, set strict to false when you read the xml in the serialiser: Root root = serializer.read(Root.class, source, false);
You need to also exclude stax-API. implementation(‘org.simpleframework:simple-xml:2.7.+’){ exclude module: ‘stax’ exclude module: ‘stax-api’ exclude module: ‘xpp3’ }
In case of Kotlin and coroutines this situation happened when I forgot to mark api service function as suspend when I call this function from CoroutineScope(Dispatchers.IO).launch{}: Usage: val apiService = RetrofitFactory.makeRetrofitService() CoroutineScope(Dispatchers.IO).launch { val response = apiService.myGetRequest() // process response… } ApiService.kt interface ApiService { @GET(“/my-get-request”) suspend fun myGetRequest(): Response<String> }
