GCM not working with app

GCM not working with app

I'm having issues getting GCM working for my app. My webapp is using
django and uses the following app: https://github.com/bogdal/django-gcm
I have the API_KEY set properly, as per instructions on these pages:
http://developer.android.com/google/gcm/index.html
I have the following on my manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.testapp"
android:launchMode="singleInstance"
android:versionCode="11"
android:versionName="1.2.0">
<uses-sdk android:minSdkVersion="10" android:targetSdkVersion="17"/>
<permission android:name="com.testapp.permission.C2D_MESSAGE"
android:protectionLevel="signature"/>
<!-- GCM requires a Google account. -->
<uses-permission android:name="android.permission.GET_ACCOUNTS"/>
<!-- Keeps the processor from sleeping when a message is received. -->
<uses-permission android:name="android.permission.WAKE_LOCK"/>
<!-- This app has permission to register with GCM and receive message -->
<uses-permission
android:name="com.google.android.c2dm.permission.RECEIVE"/>
<uses-permission android:name="com.testapp.permission.C2D_MESSAGE"/>
<application
android:icon="@drawable/icon"
android:label="@string/app_name"
android:theme="@style/Theme.MyTheme">
<receiver
android:name="com.testapp.pager.GCMBroadcastReceiver"
android:permission="com.google.android.c2dm.permission.SEND">
<intent-filter>
<action
android:name="com.google.android.c2dm.intent.RECEIVE"/>
<action
android:name="com.google.android.c2dm.intent.REGISTRATION"/>
<category android:name="com.testapp"/>
</intent-filter>
</receiver>
<service android:name=".pager.GCMIntentService"
android:enabled="true"/>
<service android:name=".services.TimeService"/>
</application>
</manifest>
Can somebody please point me in the right direction?
