The Extensible Messaging and Presence Protocol (XMPP) is a communications protocol based on XML. It was orginially named Jabber and is used for near real-time, instant messaging between entities (humans, embedded devices).

3. XMPP Intent

MAXS Transport XMPP provides a service that allows Apps to send an XMPP message by issuing an Intent. Since the service is not protected by an permission, a shared token has to be specified for security reasons.

The Intent action is org.projectmaxs.transport.xmpp.SEND_XMPP_MESSAGE. The required extras are

Extra Type Description
org.projectmaxs.transport.xmpp.TOKEN String The shared token as set in the settings of MAXS Transport XMPP
org.projectmaxs.transport.xmpp.TO String The JID the message should be sent to
org.projectmaxs.transport.xmpp.BODY String The body of the message

You can test the XMPP Intent with adb:

adb shell am startservice \
  -a org.projectmaxs.transport.xmpp.SEND_XMPP_MESSAGE \
  -e org.projectmaxs.transport.xmpp.TOKEN foo \
  -e org.projectmaxs.transport.xmpp.TO \
  -e org.projectmaxs.transport.xmpp.BODY test
