Android JSONObject.getString() scrambles large numbers

When I try to send JSONObject from server I have number 00420123456789 like phone number (but saved in DB and sent from the server as string!!)

When I get it in android it is in JSONObject shortened to 420123456789 it is no problem for me I can add two more zeros at the beginning

BUT

when I try String s = JSONObject.getString("myNumber") it returns 4.20607238118E11.

Can somebody tell me anything to this?? I don't know what to do tried a lot of google searching but it looks like no one is sending long numbers in JSON.

EDIT: shortened and changed personal data but this is JSON I am receiving:

{
        Id: 1,
        name: myName,
        city: Prague,
        street: Karlovarska,
        street_number: 48,
        postal_code: 50280,
        phone_number: 420123456789,
        email: [email protected],
        webpage: www.aaa.com/page.aspx,
    }

another problem appeared: in JAVA(android) using 

JSONObject json = new JSONObject(jsonStringFromWeb);

everything works until I send webpage with "/" I tried escaping by // or / but nothing works...

Change the JSON to make phone_number be a string, not an integer:

{ Id: 1, name: myName, city: Prague, street: Karlovarska, street_number: 48, postal_code: 50280, phone_number: "420123456789", email: [email protected], webpage: www.aaa.com/page.aspx, }

After all, not all phone numbers in the world are integers.

Similarly, street_number and postal_code should be strings, as not all street numbers (221B) or postal codes (most of them in the UK) are integers.

When you put into the long type, it may lead to this situation, you can pass in the incoming String type. like this：

JSONObject json=new JSONObject();
json.put("myNumber",420123456789.toString())
