Boa tarde, estou tendo problemas ao abrir conexão ao meu banco de dados do firebird pelo android. Meu primeiro teste foi usando MySql e ocorreu tudo normalmente, tentei migrar para o firebird mas não estou conseguindo abrir conexão.

Estou fazendo a conexão pela AsyncTask usando o JDBC port do Firebird para android (Jaybird2_2_4).

*Deixando claro que é apenas para estudo, não havendo a possibilidade de um webservice, apenas conexão direta.

        codigo = ""+edit[0].getText();

        codigo = String.format("%14s", codigo).replace(' ', '0');

        System.err.println("Codigo selecionado : "+codigo);

        String query = "SELECT DS_PRO FROM PRODUTO WHERE CD_PRO = '"+codigo+"'";

        try{

            Class.forName("org.firebirdsql.jdbc.FBDriver").newInstance();

            System.err.println("jdbc created");

        }catch(Exception e){

            System.err.println("Cannot create connection");

        }

        try{

        Properties props = new Properties();

        props.setProperty("user", "POINTER");

        props.setProperty("password", "senhabd");

        props.setProperty("encoding", "WIN1252");

            try{

            System.err.println("creating connection");

                java.sql.Connection connection = DriverManager.getConnection("jdbc:firebirdsql:localhost/3050:c:/Fenix/FENIX.FDB",props);

                System.err.println("created connection");

            }

            catch(Exception e){

                System.err.println(e.getMessage());

            }

        }

        catch(Exception e){

            System.err.println(e.getMessage());

        }

Esse é o código que estou utilizando.

A mensagem do logcat que estou tendo é essa:
