Error when connect Android with ontology

Question

I want to connect Android to an owl file using the code below, but this line

model = ModelFactory.createOntologyModel(OntModelSpec.OWL_MEM_TRANS_INF)

throws an exception.

public class OntoQuery {
    private Model model;

    public OntoQuery(String inputFileName) {
        model = ModelFactory.createOntologyModel(OntModelSpec.OWL_MEM_TRANS_INF);
        InputStream in = FileManager.get().open(inputFileName);
        if(in == null) {
            throw new IllegalArgumentException("File: " + inputFileName + " not found");
        } else {
            model.read(in, "RDF/XML");
        }
    }

    public String executeQuery(String queryString) throws UnsupportedEncodingException {
        Query query = QueryFactory.create(queryString);
        QueryExecution qe = QueryExecutionFactory.create(query, this.model);
        Throwable var5 = null;

        String fieldValue;
        try {
            ResultSet results = qe.execSelect();
            ByteArrayOutputStream go = new ByteArrayOutputStream();
            ResultSetFormatter.out(go, results, query);
            fieldValue = new String(go.toByteArray(), "UTF-8");
        } catch (Throwable var15) {
            var5 = var15;
            throw var15;
        } finally {
            if(qe != null) {
                if(var5 != null) {
                    try {
                        qe.close();
                    } catch (Throwable var14) {
                        //var5.addSuppressed(var14);
                    }
                } else {
                    qe.close();
                }
            }
        }

        return fieldValue;
    }
}
