so far i have worked with java only recently like a hand in hand i am working with kotlin when it comes to java i was making some printer connection to my mobile application that was like a third party application where you have to give some command from your application so that print has to come through over wifi connection without any usb connection so that was a complicated part through AIDL i have made it to communicate with the printer so that was the piece of code like where AIDL callbacks the same callback you have to implement in server end also if it is not like it will not work so that both AIDL has to match so that callbacks has to be overridden then only it will work so there i have found a great difficulty but later on now i understood what it is
