Question

Gson has some odd behavior when I try to convert a string to json. The code below transforms string draft into json responses. Is there a way to prevent gson from adding the

Answer 1

This work for me.

Step 1: Copy the ObjectTypeAdapter in gson into the project, keeping the path the same as in gson Like this

com
  - xxx
    - xxx
com
  - google
    - gson
      - internal
        - bind
          ObjectTypeAdapter

Step 2: Modify ObjectTypeAdapter

case NUMBER:
  return in.nextDouble();

Modified to

case NUMBER:
  String number = in.nextString();
  try {
    return Long.valueOf(number);
  } catch (NumberFormatException e) {
    return Double.valueOf(number);
  }

OK. Gson will prioritizes the ObjectTypeAdapter in the project.
