Strange “nameValuePairs” key appear when using Gson

Question

I am trying to rebuild an Object from its fields( i get the fields as a JSONObject), something like this:

JSONObject jObj = new JSONObject();

Answer 1

Finally, I found a solution for this problem. Instead of saving my JSONObject using Gson, I will simply save it as string using toString() and rebuild the original JSONObject later by wrapping saved string into JSONArray as in following example.

In my case i din't have choice to change JSONObject to com.google.gson.JsonObject as suggested in accepted answer because my 90% coding was done and such a change would have ruined my days and nights. Following is the piece of code that worked for me:

For example, save JSONObject to shared preference (or DB) like this:

public void saveJson(JSONObject reqJson) {
    sharedPref.editor().put("savedjson_key",reqJson.toString()).apply();
}

Then, when you want to rebuild the original JSONObject:

 public JSONObject getSavedJson() {
    String reqJson=sharedPref.getString("savedjson_key");
    if (reqJson != null) {
        try {
            JSONArray arr = new JSONArray(("["+reqJson+"]").replaceAll("\\\\", ""));
            return arr.getJSONObject(0);
        } catch (JSONException e) {
            e.printStackTrace();
        }

    }
    return null;
}
