In a nutshell, libraries are a group of behavior implementations that are written in computer languages and have a clearly defined interface. This includes libraries for Android.
Among other things, these libraries typically contain configuration data, message templates, help data, prewritten code and subroutines, variables, and classes.
1. Retrofit
Retrofit is a Java and Android type-safe REST client that uses annotations to intelligently translate an API into a client interface. Before, if you wanted to send a network request, you had to run an Async task class and then use an HTTPS URL Connection to retrieve data. This wasn’t the best solution for dealing with APIs that returned a lot of data. Retrofit has now made this right.
With merely annotations in Retrofit, one can easily alter endpoints and headers, add a request body and query parameters, and choose request methods. Additionally, this Android library uses converters to take care of parsing POJOs.
To begin, add dependencies to your app’s build.gradle file.
2. Glide
One of the best brand-new Android libraries for developers is Glide, another highly regarded image loader that is run by Bumptech. Not only that, but Google also recommends it directly.
When handling image loading and caching, Glide not only supports animated GIFs but also aids in fetching, decoding, and displaying video calls, photos, and these GIFs. Additionally, because HttpUrlConnection is the default network stack, it has a versatile API that enables programmers to plug in any network stack.
This library’s main goal is to make any list of images scroll as smoothly as possible. Additionally, it works well if you need to retrieve, resize, or even display a remote image.
3. Gson
To transform Java Objects into their JSON representation, Gson is a Java library that can be utilized. Another application for it is to translate a JSON string into a Java object. Any Java object, including those that are already in existence and for which you don’t have the source code, can be used with Gson.
Several open-source solutions exist that can translate Java objects into JSON. On the other hand, the majority of them demand that you add Java annotations to your classes, which you cannot accomplish without access to the source code. The use of Java Generics is likewise not universally supported. Both of these are prized design objectives by Gson.
4. LottieFiles Animation
The goal of this is to improve the mobile application’s user interface by including Lottie animation files. Vector animation files for the Lottie animations are available for free usage. The official website can be accessed here to access these animation files. Uber, Netflix, Google, Airbnb, Shopify, and other well-known applications use it.
5. Room Database
There are numerous methods that users’ devices might store app data. In addition to shared preferences and SQLite tables, there are numerous other options to save data on the user’s device.
A more reliable database is made possible by Room, a persistence package that offers an abstraction layer over the SQLite database. We can quickly establish a database and carry out CRUD activities with the aid of room. The three main components of the room are Entity, Database, and DAO.
Suppose I made a mistake? Please tell me in the comments. I aspire to get better.
Don’t clap 👏 even once. Give the entire plus fifty, for the benefit of everyone.
