This will give JSONException, because "NAME" and other keys are missing from JSON arrays first index object.

@amitsingh try it and then comment again that is why index starts from 1 see for loop

amit singh Over a year ago

With try-catch block, you can stop your app from crashing, but you cannot parse your jason like this.

@amitsingh did you try before posting the comment

amit singh Over a year ago

Use this

JSONObject json = new JSONObject(jsonstring);
json.getString("name");
....

Java has it's own JSON library although I prefer Google GSON which is more OO oriented: Google GSON
