With Apache Kafka, the physical broker a message is written to depends on the number of partitions, and which broker is the leader of the partition the record is written to. In some messaging systems the broker may be identical or co-located with (some) message consumers. The broker handles the actual delivery, re-delivery, persistence, etc. Physically: some message broker (which can be e.g., a single server, or a cluster, or a local process reached via IPC).This envelope may offer the possibility to convey additional metadata, often in key/value form.Ī message is sent by a message producer to: Next major version SHOULD NOT be released prior to October 1, 2023).Īlthough messaging systems are not as standardized as, e.g., HTTP, it is assumed that the following definitions are applicable to most of them that have similar concepts at all (names borrowed mostly from JMS):Ī message is an envelope with a potentially empty payload.

Third-party text messaging apps are at a disadvantage right now since they lack RCS support, but this API will mean you can use your favorite text messaging app and enjoy the benefits of RCS. We haven't found an announcement from Google on this Android Messages API yet, but we're hoping to see it opened up soon. This could mean that all RCS messages sent through a third-party messaging app will use Google's Chat service, which is thus far the most widely used RCS implementation since none of the carriers' versions have taken off. While we were hoping to see Google open up the Android platform's RCS API, there's potentially one big advantage to having Google Messages handle message routing. The permission is grouped under the SMS category, which makes sense since it's only intended to be used by messaging apps. This is also hinted at in the strings embedded above, which state that an app that holds the permission can "send messages without any extra approvals", implying that approval has to be given initially. The permission type is listed as "dangerous", which means that it won't be granted to a requesting app without a confirmation being displayed to the user. Within the Google Messages app's Manifest file, we also found the permission that messaging apps will have to declare: These strings clearly describe a permission that third-party messaging apps can request to be able to send SMS, MMS, or RCS messages through the Google Messages app. Permission to send SMS/MMS/RCS messages using Android Messages API It will have an access to send messages without any extra approvals. When Google Messages rolled out today on Google Play, we decoded the APK and discovered the following strings in its resources: With this permission the app will be allowed to send SMS/MMS/RCS using Android Messages. This is because these features are currently unimplemented in the live build and may be pulled at any time by the developers in a future build. An APK teardown can often predict features that may arrive in a future update of an application, but it is possible that any of the features we mention here may not make it in a future release.
