        new AttemptLogin().execute();
        break;


    default:
        break;
    }
}

class AttemptLogin extends AsyncTask<String, String, String> {

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        pDialog = new ProgressDialog(Login.this);
        pDialog.setMessage("Attempting login...");
        pDialog.setIndeterminate(false);
        pDialog.setCancelable(true);
        pDialog.show();
    }

    @Override
    protected String doInBackground(String... args) {
        // TODO Auto-generated method stub
        // Check for success tag
        int success;
        String username = user.getText().toString();
        String password = pass.getText().toString();
        try {

            List<NameValuePair> params = new ArrayList<NameValuePair>();
            params.add(new BasicNameValuePair("email", username));
            params.add(new BasicNameValuePair("motdepasse", password));

            Log.d("request!", "starting");
            // getting product details by making HTTP request
            Log.i("tesssssssssssssssssssst", "test");
            JSONObject json = jsonParser.makeHttpRequest(LOGIN_URL, "POST",
                    params);

            // check your log for json response
            Log.d("Login attempt", json.toString());

            // json success tag
            success = json.getInt(TAG_SUCCESS);
            if (success == 1) {
                Log.d("Login Successful!", json.toString());
                // save user data
                SharedPreferences sp = PreferenceManager
                        .getDefaultSharedPreferences(Login.this);
                Editor edit = sp.edit();
                edit.putString("email", username);
                edit.commit();
                finish();
                return json.getString(TAG_MESSAGE);
            } else {
                Log.d("Login Failure!", json.getString(TAG_MESSAGE));
                return json.getString(TAG_MESSAGE);
            }
        } catch (JSONException e) {
            e.printStackTrace();
        }
        Log.i("tesssssssssssssssssssst", "test");
        return null;

    }

    protected void onPostExecute(String file_url) {
        pDialog.cancel();
        if (file_url != null) {
            Toast.makeText(Login.this, "", Toast.LENGTH_LONG).show();
        }

    }

}

}

You are missing the protocol for your URL. Use http:// or https:// when you set your LOGIN_URL

See here for more details: Target host must not be null, or set in parameters

look at the logcat:

Target host must not be null, or set in parameters. scheme=null, host=null, path=sorifgroupcom.ipage.com/Android/login.php

it is taking everything as a path, without host. And thats because you didnt specify the scheme.

change

private static final String LOGIN_URL = "sorifgroupcom.ipage.com/Android/login.php";

to

private static final String LOGIN_URL = "http://sorifgroupcom.ipage.com/Android/login.php";

thanks Carlos i change that and it give another error Error parsing data org.json.JSONException: Value Fatal of type java.lang.String cannot be converted to JSONObject – soufiane.dev Jan 08 '14 at 01:00
thats another problem, probably the results from that URL are not correctly formated. if you want, accept this answer and then create a new question , since you will have to provide with some different information (and give me the link of the question if you want) – Carlos Robles Jan 08 '14 at 01:04
