How to send Push Notifications with Parse.com Cloudcode

Question

I want to send a Push Notification with Cloudcode on Parse.com.

The push notification should be sent to all android devices that are subscribed to a specific channe

Answer 1

All you need is an installation query, along with an accompanying push. For example:

var pushQuery = new Parse.Query(Parse.Installation);
pushQuery.containedIn("user", userlist);
Parse.Push.send({
  where: pushQuery, 
  data: {
     alert: "Your push message here!"
  }
}, {
  success: function() {
    response.success("pushed");
  }, error: function(error) {
   reponse.error("didn't push");
  }
});

That installation query can be a query based on a channel, and there are other specifications you can make for the push query, given in the documentation:
