Question

I have to parse a json whom a field can be empty:

{"fullField":"ok","canBeEmpty":""}

if I try to parse this string overall parsing fails with a “no value for canBeEmpty”.
For each json item I execute:

json_data.getString("field"); //throws exception if empty

I’d like to still keep the parsing, setting the canBeEmpty value to a default string…is it possibile?

Answer 1

you can use JSONObject.JSONObject(String name) to check if any name is exist or not in json object as:

if(JSONObject.isNull("field")){
// do something here
}
else{
//do something here
}
