What experience do you have in developing native solutions for implementing network requests on the Android platform?

I have experience working with various approaches:
-
HttpURLConnection: A basic class providing direct access to HTTP. Requires manual handling of streams, JSON/XML parsing, thread pool management. Suitable for simple requests or deep understanding of network operations.
-
Apache HttpClient: A popular library before Android 6.0 (API 23). Offered a more convenient API compared to
HttpURLConnection, but had support issues in newer Android versions. -
Volley: A library from Google designed for fast network operations. Simplifies requests, caching, image handling. Used for medium complexity applications.
// Example of using Volley val queue = Volley.newRequestQueue(context) val url = "https://api.example.com/data" val stringRequest = StringRequest(Request.Method.GET, url, Response.Listener<String> { response -> // Handle successful response }, Response.ErrorListener { error -> // Handle error }) queue.add(stringRequest) -
Retrofit: A type-safe HTTP client from Square built on OkHttp. Significantly simplifies REST API interactions through a declarative approach and customization options (converters, interceptors). The preferred choice for most modern applications.
interface ApiService { @GET("users/{id}") suspend fun getUser(@Path("id") userId: Int): User } // Creating Retrofit client val retrofit = Retrofit.Builder() .baseUrl("https://api.example.com/") .addConverterFactory(GsonConverterFactory.create()) .build() val apiService = retrofit.create(ApiService::class.java) // Making a request with coroutines GlobalScope.launch { try { val user = apiService.getUser(1) // Handle data } catch (e: Exception) { // Handle error } } -
OkHttp: A powerful and efficient HTTP client. Forms the basis of Retrofit and other libraries. Excellent for low-level request management, HTTP/2 support, caching, interceptors.
-
Working with Multipart requests: Sending files and data in a single request.
-
Error handling: Implemented mechanisms for intercepting and handling API errors (e.g., HTTP status codes, custom server errors).
-
Response caching: Applied caching strategies to improve performance (e.g., HTTP-level or app-level caching).
-
Timeouts and retries: Configured timeout parameters and implemented retry logic for transient network issues.
-
Security: Worked with HTTPS, certificate validation.
Comparison of popular libraries:
| Library | Foundation | Type safety | Complexity | Usage |
|---|---|---|---|---|
| HttpURLConnection | Java/Android API | No | High | Low-level access |
| Volley | Custom | No | Medium | Simple/medium applications |
| Retrofit | OkHttp | Yes | Low | REST API, modern applications |
| OkHttp | Custom | Partial | Medium | Low-level management |
I prefer to use Retrofit because of its convenience, type safety, and integration with coroutines, which greatly simplifies asynchronous programming. At the same time, I understand and can use OkHttp for more fine-grained control or when Retrofit is not sufficient.
