I am implementing GCM (Google Cloud Messaging- PUSH Notifications) in my application. I have followed all the steps given in GCM tutorial from developer.android.com

My application's build target is pointing to Goolge API 8 (Android 2.2 version).

I am able to get the register ID from GCM successfully, and I am passing this ID to my application server. So the registration step is performed successfully.

Now when my application server sends a PUSH message to my device, the server gets the message as SUCCESS=1 FAILURE=0, etc., i.e. Server is sending message successfully, but my device never receives the message.

After searching alot about this, I came to know that GCM pushes messages on port number 5228, 5229 or 5230.

Initially, my device and laptop was restricted for some websites, but then I was granted all the permissions to access all websites, so I guess these port numbers are open for my device.

So my question is: I never receive any PUSH message from GCM. My onMessage() from GCMIntenService class is never called. What could be the reason?

Please see my following code and guide me accordingly:

I have declared following in my manifest:

<uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="8" />

    <permission
        android:name="package.permission.C2D_MESSAGE"
        android:protectionLevel="signature" />

    <!-- App receives GCM messages. -->
    <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />

    <!-- GCM connects to Google Services. -->
    <uses-permission android:name="android.permission.INTERNET" />

    <!-- 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" />
    <uses-permission android:name="package.permission.C2D_MESSAGE" />
    <uses-permission android:name="android.permission.INTERNET" />

    <receiver

                <action android:name="com.google.android.c2dm.intent.REGISTRATION" />

                <category android:name="packageName" />
            </intent-filter>
        </receiver>
        <receiver
            android:name=".ReceiveBroadcast"
            android:exported="false" >
            <intent-filter>
                <action android:name="GCM_RECEIVED_ACTION" />
            </intent-filter>
        </receiver>

        <service
            android:name=".GCMIntentService"
            />
