Simple AIDL Communication

AIDL is Android's way of achieving IPC.

The Android Interface Definition Language (AIDL) is similar to other IDLs: it lets you define the programming interface that both the client and service agree upon in order to communicate with each other using interprocess communication (IPC).

AIDL consists of 3 parts:

1. AIDL file

2. Client application

3. Server application
