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" />
