Overview of the manifest changes:
Permission to receive C2DM messages
Access to the internet
Restrict access to your C2DM messages so no other app can see them
Declare a Receiver, that we’ll create later, that will let us receive the C2DM events
Make sure that the minSdkVersion is set so that only 2.2 and higher can access your app
<manifest package="com.example.myapp" ...>
<!-- Only this application can receive the messages and registration result -->
<permission android:name="com.example.myapp.permission.C2D_MESSAGE"
android:protectionLevel="signature" />
<uses-permission android:name="com.example.myapp.permission.C2D_MESSAGE" />
<!-- This app has permission to register and receive message -->
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<!-- Send the registration id to the server -->
<uses-permission android:name="android.permission.INTERNET" />
<application...>
<!-- Only C2DM servers can send messages for the app. If permission is not set -
any other app can generate it -->
<receiver android:name=".MyC2dmReceiver"
android:permission="com.google.android.c2dm.permission.SEND">
<!-- Receive the actual message -->
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<category android:name="com.example.myapp" />
</intent-filter>
<!-- Receive the registration id -->
<intent-filter>
<action android:name="com.google.android.c2dm.intent.REGISTRATION" />
<category android:name="com.example.myapp" />
</intent-filter>
</receiver>

</application>
