Android C2DM推送通知

我正在開發一個應用程序，並在該應用程序中需要實現推送通知。任何人都可以建議我應該如何去實施推送通知？如果我可以提供一個很好的教程，那會很棒！Android C2DM推送通知

謝謝。

//調用時，你的應用程序啓動

public void StartRegistrationNotification() 
    { 

     Intent registrationIntent = new Intent("com.google.android.c2dm.intent.REGISTER"); 
     registrationIntent.putExtra("app", PendingIntent.getBroadcast(this, 0, new Intent(), 0)); 
     registrationIntent.putExtra("sender", "[email protected]"); 
     this.startService(registrationIntent); 

}

嘿samit謝謝你的幫助。但我沒有得到NotificationAlert類。在廣播接收器中，我收到了NotificationAlert calss錯誤。 – 2011-06-08 09:36:14

嗨通知類你自己的自定義代碼。您需要的手段自定義警報或通知.... – SBJ 2011-06-08 09:38:25

嗨samit我得到了以下錯誤。 org.pushnotification.com是我的軟件包名稱。 – 2011-06-08 10:20:48

C2DM已過時，由Google Cloud Messaging for Android (GCM)已被替換。谷歌的聲明：

重要：C2DM已正式棄用2012年6月26日，。這意味着C2DM已停止接受新用戶和配額請求。沒有新的功能將被添加到C2DM。但是，使用 C2DM的應用程序將繼續工作。鼓勵現有的C2DM開發者遷移到新版本的C2DM，稱爲Google Cloud Messaging for Android（GCM）。有關更多信息，請參閱C2DM-to-GCM遷移文檔。開發人員必須使用GCM進行新的開發。

有一個demo app tutorial for GCM和也來自C2DM的migration。
