GOOGLE ANDROID C2DM TUTORIAL (ANDROID PUSH NOTIFICATIONS)

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>

   ...

</manifest>
