Loved the article ! As an amateur, I'd like to understand What makes Retrofit better than Volley?
Without going into too much detail, Retrofit is just generally much easier to use. Requests return objects rather than JSON and it's far easier to test. Retrofit supports both synchronous and asynchronous requests as well as observables. SSL pinning is a breeze. Intercepting requests is built in.
Although Google still maintain Volley, they're switching to Retrofit in all of their code examples which should tell you something.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
