What main function does the OkHttp library perform in applications?

OkHttp is a library for Android and Java that handles the execution of HTTP requests. Its main function is to simplify and optimize network interactions, providing a convenient and efficient way to send requests and receive responses from servers. It supports features such as connection pooling, caching, retries, and asynchronous calls.

Example of a simple GET request with OkHttp:

OkHttpClient client = new OkHttpClient();

Request request = new Request.Builder()
    .url("https://api.example.com/data")
    .build();

client.newCall(request).enqueue(new Callback() {
    @Override
    public void onFailure(Call call, IOException e) {
        e.printStackTrace();
    }

    @Override
    public void onResponse(Call call, Response response) throws IOException {
        if (response.isSuccessful()) {
            String responseData = response.body().string();
            System.out.println(responseData);
        }
    }
});
