you get from the server a (maybe empty) json array and you are try to convert it in a JsonObject.
instead of
JSONObject obj = new JSONObject(string);
you should do
JSONArray obj = new JSONArray(string);

the problem is with my log in activity.i was thinking it has something to do with my connection to the server?do you think i need to make another API because my code is working perfectly until i had a problem with my server.or i should reprogram my log in activity suggestion will be appreciated thank you

I will go with an AsyncTask, HttpUrlConnection and the android json library. It is a simply task to perform. Also check if something server side has changed

i tried doing it with JSONArray but then i get error in "pref_editor.putString("Name", result.getString("name"));" i need to make it an object right how can i make it in JSONArray?

You are trying to convert JsonObject to JsonArray so getting error.
You have to convert proper jsonObject to another object as per your requirement.
You can find useful demo with explanation.
If you find and trouble for parsing your json after researching this demo then let me know.
