Android development can be challenging, but several libraries and frameworks have been created to simplify the process, with RxJava, Dagger, Retrofit, Glide, and Room being among the most recommended by experienced developers. RxJava, a top library for reactive programming, allows developers to handle asynchronous operations and real-time data more efficiently, though it requires some learning. Dagger, a compile-time dependency injection framework maintained by Google, simplifies the integration of components into larger models and has recently been enhanced by Hilt to address its complexity. Retrofit offers a clean and simple way to manage REST APIs for Android and Java, supporting both synchronous and asynchronous API calls, and integrates well with RxJava. Glide, an open-source library managed by Bumptech, is highly effective for image loading and media management, simplifying the often difficult task of handling images on Android. Lastly, Room, the official ORM library for Android, provides a straightforward way to manage data storage and offline capabilities using SQLite, while also supporting Rx for seamless integration into applications.
