Question

I have an API in php, that sends data in JSON format.
I made the following code, that works fine when I am on wifi.
But when I want to download the data from the API when I am on 3g, I receive the following exception:
JSONException: End of input at character 0 of

I have no idea why it does work on wifi, but it doesn’t on mobile internet.
My code:

        JSONObject json = getJSONfromURL("http://api.myurl.com/users.json");

        JSONArray objects = json.getJSONArray("objects");
        db.setLockingEnabled(false);
        db.beginTransaction();

        for (int i = 0; i < objects.length(); i++) {
            JSONObject e = objects.getJSONObject(i);

            if(e.getString("UID") != "-1"){
                ContentValues values = new ContentValues();
                //DO DATABASE INSERT. REMOVED THIS CODE FOR READABILITY
                alldata_mProgressDialog.incrementProgressBy(1);
            }
        }

Anyone that can help me out?

You are probably getting a blank response. Its not null but the response is empty. So you are getting this error and not a Nullpointer exception
