Actually the name is just from App Inventor (because this block is missing in Kodular). The source is most probably from app inventor too

Yes, you are right , I think he meant the extension name .

The source isn’t hard actually I’ve used the JsonUtils class to decode the json:

           *
           * @param jsonString the JSON text to parse
           * @param useDicts true if YailDictionary should be used for JSON objects,
           *                 false for associative lists
           * @return the parsed object
           * @throws JSONException if the JSON is malformed
           */
          public static Object getObjectFromJson(String jsonString, boolean useDicts) throws JSONException {
            if ((jsonString == null) || jsonString.equals("")) {
              // We'd like the empty string to decode to the empty string.  Form.java
              // relies on this for the case where there's an activity result with no intent data.
              // We handle this case explicitly since nextValue() appears to throw an error
              // when given the empty string.
              return "";
            } else {
              final Object value = (new JSONTokener(jsonString)).nextValue();
              // Note that the JSONTokener may return a value equals() to null.
              if (value == null || value.equals(JSONObject.NULL)) {

The source code is isn’t similar with app Inventor code ( specially after rewriting it ). I’ve optimized it a lot to decrease the extension size.

I was talking about the block.

But its name is lengthy.

Mohamed_Tamer · October 26, 2020, 8:50am

I misunderstood I actually always see it’s very lengthy,too I will change it in the next update
