Let’s add the “ messengerexample” action to be sent from the client application to the service with intent.Begin with the Server Application Declare the filter in Manifest Thus, the two applications will be able to communicate through Message objects. In this way, the server will return the Messenger object to the client. It is guaranteed that calls will be received from at most one process/thread at a time of t.Īs in the previous example, the client will bind to the server’s service. In Messenger, the calls are queued and executed sequentially. For example, with AIDL, you are able to do concurrent operations.Messenger and AIDL method fits exactly to this situation: The developer does not need to bother with this implementation.īut as we have encountered from time to time, tools that are easy-to-implement can bring limitations, while hard-to-implement tools can provide flexibility. Messenger is much easier to implement than the AIDL technique because it creates and uses AIDL files in the background. This technique has the Binder architecture like the AIDL technique mentioned in the previous article. Messenger is a Handler sent to the remote process. Now we will improve these two applications to support the Messenger method. You can find all parts of the series at the end of the article. In the previous articles, we talked about the definition of IPC and the AIDL method, and we created client-server applications using the AIDL method.
