AIDL Color Service Server

This project demonstrates Android IPC using AIDL.

The server app exposes a remote Android Service that can be accessed from another application.

The service generates and returns a random color using Binder communication.

What This Project Demonstrates

• Android IPC (Inter-Process Communication)
• AIDL basics
• Bound Services
• Cross-app communication
• Binder communication

Flow

1. Client app binds to the exported service.
2. Client calls getColor() remotely.
3. Server generates a random color.
4. Color value is returned through Binder.

Important Notes

• The service must be exported=true to allow external apps to bind.
• Both apps must contain the exact same .aidl file.
• The package inside the AIDL file must match exactly in both projects.
• Use a fully qualified action name like:

com.devbilal.ipc.AidlColorService

instead of generic names.

• The client app must be installed on the same device.
• The server app must be installed before binding from the client app.
• bindService() may silently fail if Android cannot discover the target app.
• Logging inside onBind() and remote methods helps debugging Binder communication.
