I'm having trouble with creating fmd from byte. Error with fmd is invalid.
Here is my code

String id = jsonobject.getString("fps_thumb");

byte [] encodeByte= Base64.decode(id,Base64.DEFAULT);

Fmd m_fmdAuxiliar = UareUGlobal.GetImporter().ImportFmd(encodeByte, Fmd.Format.ANSI_378_2004, Fmd.Format.ISO_19794_2_2005);

Does anyone know?

this is the code for retrieving data from api and compare it from the reader finger print

try{
        JSONArray jsonarray = new JSONArray(http.getResponse());
        for(int i=0; i < jsonarray.length(); i++) {
        JSONObject jsonobject = jsonarray.getJSONObject(i);
        String id = jsonobject.getString("fps_thumb");
        byte[] bytes = id.getBytes(StandardCharsets.UTF_8);

        try {
        Fmd m_fmdAuxiliar = UareUGlobal.GetImporter().ImportFmd(bytes, Fmd.Format.ANSI_378_2004, Fmd.Format.ANSI_378_2004);
        m_score = m_engine.Compare(m_fmdAuxiliar, 0,m_engine.CreateFmd(cap_result.image, Fmd.Format.ANSI_378_2004), 0);

        DecimalFormat formatting = new DecimalFormat("##.######");
        m_text_conclusionString = "Dissimilarity Score: " + String.valueOf(m_score)+ ", False match rate: " +
        Double.valueOf(formatting.format((double)m_score/0x7FFFFFFF)) + " (" + (m_score < (0x7FFFFFFF/100000)
        ? "match" : "no match") + ")";

        Log.i("TAG",m_text_conclusionString);

        } catch (UareUException e) {
        e.printStackTrace();
        }

        }
        }
        catch (JSONException e){
        e.printStackTrace();
        }
