What is Retrofit2 used for?

Interaction with RESTful web services

Retrofit provides a convenient and structured interaction with web services, minimizing the need for manual coding and testing.

Automatic deserialization

Instead of manually converting JSON responses into objects, Retrofit does this automatically using libraries such as Gson or Moshi.

Flexible configuration

Retrofit allows easy customization of requests, adding interceptors, authorization tokens and more.

When should and shouldn't you use Retrofit2?

Large and medium projects

Retrofit2 is perfect for projects where there is a need for interaction with various APIs and where automatic deserialization can significantly speed up the development process.

Projects requiring high performance

Retrofit2 is optimized for speed and low resource consumption.

Applications where security is a priority

With Retrofit2, you can easily integrate various authentication and encryption mechanisms.

Very simple applications

If you just need to send one or two requests without complex logic, then using Retrofit may be excessive.

If you are already using another library for HTTP interaction and it meets all your requirements.
