https://aospguru.com/ AIDL Lab Part 2 - Create Client App
In this second part of the tutorial, we will create an AIDL client. The server app hosts a Bound Service and contains the logic to return random colours to its client. The client app calls the service and changes the button's colour within the Main activity.
