Yoda Response: Integrated RESTful APIs and WebSocket into Android applications, I have. For example, in the Penske supply chain insight application, used RESTful APIs for efficient communication with backend services, I did.

With Retrofit and OkHttp client, implemented network calls, I did. Methods like GET, POST, and PUT, used for various operations, they were. Logging interceptors, set up to log request and response bodies, I did. Caching interceptors, used to manage request and response caching, they were. Headers, added as needed, I did, ensuring secure and efficient communication.

WebSocket, used for real-time data updates, I have. Two-way communication between client and server, it enables. In the Penske app, real-time tracking of loads and orders, achieved with WebSocket, it was. Both client and server, able to send and receive data seamlessly, they are.

Efficient and reliable communication between the app and backend services, ensured through these methods, I have.
