Parse Json values using GSON that can be double or Strings

Question

I am trying to parse JSON using GSON library, but I am having some issues.

The problem is that some of the keys can contain double and String values. Here is an example:

"message":"unlimited"

But this can also be:

"message":4.0

Can anyone help me to find a solution for this?

Did you try and specific code? If so, what's the more specific problem, such as an exception on the non-string? — Palu Macil, Jul 10 '15 at 12:22

You can create a custom type for your message field, and implement a TypeAdapter for it.

@Darko, there is a great example at the link I've attached, do you want me to actually code the solution for you? – user3707125 Jul 10 '15 at 12:00

 Object aObj = jObj.get("message");

            if (aObj instanceof Double) {
               Log.d("Oobjext",":" + aObj);

            }else if(aObj instanceof String){
                Log.d("Oobjext string",":" + aObj);
            }

Most of the times, server should not be doing this. Because checking the type of "key" will be a hectic task.
