I am trying to create a client and server type of implementation. I have a background service which need to send data to client when ever a specific method is called using aidl. I am using aidl just because the client and service are in different process.
And make changes at client side when ever a method is invoked.
Can some one help me with this Explained with examples.
1. I am able to bind to service but I am not able to unbind from the service even after calling unbind(Serverconnection) from the client side.
I am trying to use [this book][1] at page number 141 Callbacks with AIDL.
