mod_fcm

mod_fcm is an ejabberd module to send offline messages as PUSH notifications for Android using Google Cloud Messaging

Consider using mod_push which implements XEP-0357 and works with many PUSH services.

This module has nothing to do with XEP-0357.

The main goal of this module is to send all offline messages to the registered (see Usage) clients via Google Cloud Messaging service.

Compilation:

Because of the dependencies such as xml.hrl, logger.hrl, etc it's recommended to compile the module with ejabberd itself: put it in the ejabberd/src directory and run the default compiler.

Configuration:

To let the module work fine with Google APIs, put the lines below in the ejabberd modules section:

mod_fcm:
    fcm_api_key: "Your Google APIs key"


<iq to="YourServer" type="set">
  <register xmlns="https://fcm.googleapis.com/fcm" >
    <key>API_KEY</key>
  </register>
</iq>

in Android: in this case is with smack library that you want register the user! is importan to enable offline messages in ejabberd.yml

 ## Maximum number of offline messages that users can have:
  max_user_offline_messages:
    - 50000: admin
    - 10000

Function in java for Android!!!

 public int register_user_mod_push(final String num_register_fcm) throws UnsupportedEncodingException {
        final IQ iq = new IQ("register", "https://fcm.googleapis.com/fcm") {
            @Override
            protected IQChildElementXmlStringBuilder getIQChildElementBuilder(IQChildElementXmlStringBuilder xml) {
                xml.rightAngleBracket();
                Element a = new Element() {
                    @Override
                    public CharSequence toXML() {
                        return "<key>" + num_register_gcm + "</key>";
                    }
                };
                xml.element(a);
                return xml;
            }
        };
        iq.setType(IQ.Type.set);
        iq.setTo("biimbak.com");
        try {
            connection.sendStanza(iq);
            return 1;
        } catch (SmackException.NotConnectedException e) {
            e.printStackTrace();
