Usage

From source file:Main.java

static JSONObject ndefToJSON(Ndef ndef) {
    JSONObject json = new JSONObject();

    if (ndef != null) {
        try {//from  ww w  .j a va  2 s. c  om

            Tag tag = ndef.getTag();
            // tag is going to be null for NDEF_FORMATABLE until NfcUtil.parseMessage is refactored
            if (tag != null) {
                json.put("id", byteArrayToJSON(tag.getId()));
                json.put("techTypes", new JSONArray(Arrays.asList(tag.getTechList())));
            }

            json.put("type", translateType(ndef.getType()));
            json.put("maxSize", ndef.getMaxSize());
            json.put("isWritable", ndef.isWritable());
            json.put("ndefMessage", messageToJSON(ndef.getCachedNdefMessage()));
            // Workaround for bug in ICS (Android 4.0 and 4.0.1) where
            // mTag.getTagService(); of the Ndef object sometimes returns null
            // see http://issues.mroland.at/index.php?do=details&task_id=47
            try {
                json.put("canMakeReadOnly", ndef.canMakeReadOnly());
            } catch (NullPointerException e) {
                json.put("canMakeReadOnly", JSONObject.NULL);
            }
        } catch (JSONException e) {
            Log.e(TAG, "Failed to convert ndef into json: " + ndef.toString(), e);
        }
    }
