Answer 1

This is sample php code for inserting values into database..

<?php
    $host='127.0.0.1';
    $uname='root';
    $pwd='password';
    $db="android";

    $con = mysql_connect($host,$uname,$pwd) or die("connection failed");
    mysql_select_db($db,$con) or die("db selection failed");

    $wmail=$_REQUEST['email'];
    $password=$_REQUEST['password'];

    $flag['code']=0;

    if($r=mysql_query("insert into sample values('$email','$password') ",$con))
    {
        $flag['code']=1;
        echo"hi";
    }

    print(json_encode($flag));
    mysql_close($con);
?>

and in Android

private void makeJsonObjReq() {

        Map<String, String> postParam= new HashMap<String, String>();
        postParam.put("email", "[e-mail]");
        postParam.put("password", "somepasswordhere");

    JsonObjectRequest jsonObjReq = new JsonObjectRequest(Method.POST,
        You_Url, new JsonObject(postParam),
        new Response.Listener<JSONObject>() {

            @Override
            public void onResponse(JSONObject response) {
                Log.d(TAG, response.toString());


            }
        }, new Response.ErrorListener() {

            @Override
            public void onErrorResponse(VolleyError error) {
                VolleyLog.d(TAG, "Error: " + error.getMessage());

            }
        }) {

    /**
     * Passing some request headers
     * */
    @Override
    public Map<String, String> getHeaders() throws AuthFailureError {
        HashMap<String, String> headers = new HashMap<String, String>();
        headers.put("Content-Type", "application/json; charset=utf-8");
        return headers;
    }
};

// Adding request to request queue
AppController.getInstance().addToRequestQueue(jsonObjReq,tag_json_obj);

// Cancelling request
// ApplicationController.getInstance().getRequestQueue().cancelAll(tag_json_obj);       
}

And also this is just a sample code For you to learn.. I haven't tested the PHP code..Make proper changes to and also add the required params

Hope this helps
