I am receiving following json from server with pointer data type

[

"abc":{"__type":"Pointer","className":"ABC","objectId":"iHHyf1Rerw"}

ParseObject obj = parseObject.get(position).getParseObject("abc");

now i am trying to fetch

obj .getString("colname")

but i am getting colname not exists

When you query parse objects with pointer you need to use include in order to fetch also the pointer along with the query data.

After you specify the include parse-server will fetch also the pointer data (and not only the reference) so in order to do it you need to write you query in the following way (from parse docs):

Please notice that there they use include in order to also populate the post parse object which exist under the comment so in your case you need to use query.include("abc")

Try this :

ParseObject obj = parseObject.get(position).getParseObject("abc");
if(obj.has("__type"){
    String type = obj.getString("__type");
}if(obj.has("className"){
    String className = obj.getString("className");
}if(obj.has("objectId"){
    String objectId = obj.getString("objectId");
}
