Presence Management - user status

API and documentation

https://matrix.org/docs/spec/client_server/latest#id62

Change SDK side

• Create a PresenceService
• Implement an API in PresenceService to set the status of the current user using https://matrix.org/docs/spec/client_server/latest#put-matrix-client-r0-presence-userid-status
• Implement an API in PresenceService to retrieve the status of any user using https://matrix.org/docs/spec/client_server/latest#get-matrix-client-r0-presence-userid-status
• Handle the presence update from the sync response (see https://matrix.org/docs/spec/client_server/latest#get-matrix-client-r0-sync):

  "presence": {
    "events": [
      {
        "content": {
          "avatar_url": "mxc://localhost:wefuiwegh8742w",
          "last_active_ago": 2478593,
          "presence": "online",
          "currently_active": false,
          "status_msg": "Making cupcakes"
        },
        "type": "m.presence",
        "sender": "@example:localhost"
      }
    ]
  },

• See how those data ^ can be stored in the session DB to be kept up to date. Probably a new Entity will have to be created (to be discussed)

Change application side

• Integrate the design update regarding presence: list of impacted screens to be defined

Presence supports by the homeserver

Note that matrix.org has disabled the presence management for performance reason. We should avoid displaying (wrong) presence information if it’s disabled on the homeserver, and we will be able to know that with https://github.com/matrix-org/matrix-doc/pull/1862

• In the mean time, we can use the local config to disable presence locally, based on the user homeserver URL as per https://github.com/vector-im/element-web/blob/develop/element.io/app/config.json#L28. The config file on Element Android is here

So does closing this ticket mean Presence in Element is going to be coming back now or what? @ariskotsomitopoulos

@croulibri that function is definitely absent in Element/RiotX, imo it should replace the verified shield in the DM list, showing offline/online/etc, and having the E2EE shield be at the top bar of the conversation detail instead
