404 Not Found in django admin page when using django-non-rel for google app engine

I am using python 2.7 and django 1.8 and django-non-rel to make my project run on google app engine for django non-rel. When i open http://127.0.0.1:8000/ it works fine and takes me to the google app engine sdk page.. But when i go to http://127.0.0.1:8000/admin/ , I get error -

404 Not Found The resource could not be found.

Please help me to set up the admin page.

My urls.py file is this -

from django.conf.urls import *
from django.contrib import admin
import dbindexer

handler500 = 'djangotoolbox.errorviews.server_error'

# django admin
admin.autodiscover()

# search for dbindexes.py in all INSTALLED_APPS and load them
dbindexer.autodiscover()

urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'bookncart.views.home', name='home'),
    # url(r'^bookncart/', include('bookncart.foo.urls')),

    # Uncomment the admin/doc line below to enable admin documentation:
    # url(r'^admin/doc/', include('django.contrib.admindocs.urls')),

    # Uncomment the next line to enable the admin:
    url('^_ah/warmup$', 'djangoappengine.views.warmup'),
    url(r'^admin/', include(admin.site.urls)),
)

The settings.py file is this -
