“A JSONArray text must start with '[' at character 1 of null”

Question

Just wondering what that error could mean? I get it from the following code..

 try{
    JSONArray jArray = new JSONArray(result);
    for(int i=0;i

        

Answer 1

Result is null, apparently. Or it simply does not start with [. Print it out before calling JSONArray to see.

Also take a look at the JSONArray source. It is expecting JavaScript array syntax, e.g.:

['this', 'is', 'array', 'syntax']

Answer 2

text.trim(); text.trim();

Text is the json file or string , do this at least two times one after another will resolve the problem 99.9%.
