 you should run php by giving your own values. Then you should use php programs 

  in android. 






















 output:



























click insert button




























you will get record added successfully message after Clicking Button.

Then click back button -->  Retrieve button --> Enter number which is given while inserting -->Click button --> you will get record which is inserted in database.

    3. You must pass static values while run insert.php alone. When you run this from android you must get values using POST or GET method.

    1. you can't get string as JSONObject. You can design the JSON code depends on the result which you can get from server. The result is mixing of strings,JSONObjects and JSONArray.
