How does Retrofit integration with OkHttp improve network request handling in Android applications?

Integration of Retrofit with OkHttp improves network request handling in Android applications through the following advantages:

• Efficient management of HTTP connections: OkHttp supports connection pools and reuse of TCP connections, reducing latency.
• Response caching: OkHttp can cache HTTP responses, decreasing the number of network requests.
• Support for interceptors: allows easy addition of logs, headers, error handling, and more.
• Asynchronous operation and convenience: Retrofit uses OkHttp as its HTTP client, providing a user-friendly API for request description and automatic response conversion.

Example of creating Retrofit with an OkHttp client:

val okHttpClient = OkHttpClient.Builder()
    .addInterceptor(HttpLoggingInterceptor().apply {
        level = HttpLoggingInterceptor.Level.BODY
    })
    .build()

val retrofit = Retrofit.Builder()
    .baseUrl("https://api.example.com/")
    .client(okHttpClient)
    .addConverterFactory(GsonConverterFactory.create())
    .build()

This allows writing clean, efficient, and scalable network code.
