title: Android & (millions of) push notifications
body: <p>I'm working on the Android version of an application I first created on iPhone and this application requires to send (if it's as successful as its iPhone version) up to millions of push notifications to users daily.</p>
  
  <p>I naively thought the Android platform had a push notifications service as its sibling so I decided to look at this feature at the end of development and now here i am!</p>
  
  <p>I searched stackoverflow for answers about this feature (issue ?) and found several options (thanks guys!) BUT did any of you guys was able to achieve such a feature with such a volume?</p>
  
  <p>Here's the options I found :</p>
  
  <ul>
  <li><a href="http://code.google.com/android/c2dm/" rel="nofollow noreferrer">Google's C2DM Framework</a> : my first issue is that it's for Android 2.2 + only but I may consider it if there wasn't this <a href="http://code.google.com/android/c2dm/quotas.html" rel="nofollow noreferrer">200.000 notifications a day quota</a>;  did any of you guys requested more quota from Google ?</li>
  <li><a href="http://tokudu.com/2010/how-to-implement-push-notifications-for-android/" rel="nofollow noreferrer">MQTT</a> : this solution looks good and the sample code provided by Anton Lopyrev is helpful (and Dale Lane blog posts are a good read); this is the option I'm using right now but I have no idea about how it may react with thousand of users (I also have trouble with the server (mosquitto) OR the service (I don't know yet) and I am not able to receive notifications sometimes with 2 users :p)  </li>
  <li><a href="https://stackoverflow.com/questions/1243066/does-android-support-near-real-time-push-notification/5695867#5695867">XMPP</a> : it looks like the best option (yet ?) but I haven't tried it yet; did any of you guys use this solution ?</li>
  </ul>
  
  <p>I've read about Xtify or Urban Airship but none of these commercial solutions may help (volume or cost).</p>
  
  <p>Thanks for any tips! </p>
  
  <p><strong>Edit :</strong> my goal is to be able to send up to 5,000,000 notifications a day </p>
