Additionally, specific libraries like ExoPlayer, Retrofit, Picasso, Glide, and Dagger2 are mentioned for their unique capabilities in facilitating various development needs.

1. Where All Libraries & Data
Required For Android App
Development Are Present
Mobile app development has a lot in store for the up and coming global
transformation. The changes that we are witnessing right now will soon be
established as a foundation for future developments. Businesses all over the
world are curious to discover a seamless way to dwell under the unmatchable
advantages that it delivers.
Since app technology holds such colossal value in the market, it is better for us
that we clearly understand the various aspects attached to it. First and
foremost, it is necessary that we look into the best libraries of 2020 for android

2. app development. So today in this article, we will be learning more about the
same.
This brief introduction to the variety of libraries can help you a lot in Android
development.
An Introduction To Android Libraries
Choosing the right library can help a team of developers with immaculate
performance and user experience. They are a prominent part of development
that acts as a game-changer. They can simplify the process and make the
developer’s life easy by delivering ready-made codes. For the android studio,
the integration process is really very simple. All you have to do is add the
library path to build.gradle. To specify the presence of the repository path, in
case there is any.
It is okay to be a little confused while choosing a library. But in order to
eradicate the confusion, here we have listed some pointers to solve your
problem.
Key Features To Select A Library
Before selecting any library for any specific purpose, make sure that it fulfills all
your requirements and follows the pointers mentioned below-
It must use a simple API
It must have a gargantuan user base
It must provide a high-quality
It must not compromise on consistency while delivering a solution for a non-
trivial and real problem.
It must have an active developer community
It must not transform the overall architecture
These are the six most important conditions for selecting a library.

3. Top Libraries Of 2023 For Android App Development
As the android platform is continuously subjected to transformations, it is
mandatory that developers remain up to date about the libraries. One needs
to match the growth of the fast-paced field of software development, in order
to ace the game. Let us look into the different kinds of libraries that everyone
must know about.
Libraries For Videos
Adding videos in an app during the development is a tough nut to crack. There
are several details that one must take care of. This can get a little tricky. Let us
take a look into its example.
ExoPlayer
Created by the tech giant Google, this is a very famous Android media player
library. It is a better alternative for Android’s MediaPlayer API. It is used by the
developers for playing both video and audio locally. It acts as a great support
for the features that are not supported by Android’s MediaPlayer API. For
example, smooth streaming adaptive playback, and DASH.
With its simple and easy customization, this library is winning the hearts of
many android app developers .
Libraries For Networking
For every mobile app, the option of networking is mandatory. It is a must to
have some sort of network communication to execute one function or the
other. Earlier the process of making a request for the network required
execution of the Async task. It also required the usage of HttpUrlConnection to
get data. This approach does not assure 100% results while dealing with APIs
that return large data.
The use of the below-mentioned networking library can help the developers to
completely optimize the process. They will prove a lot helpful in managing the
device resources and threads properly.

4. Retrofit
For Android development, Retrofit is a highly used networking library.
Developed by Square, it carries the potential of-
Adding a request body
Query parameters
Manipulate endpoints
Choose request methods
Manipulate headers
Libraries For Testing
It is the process that helps to detect bugs in code. Check out one of its coolest
examples-
Junit
It is used for unit testing. It contains methods to check an expected result with
large use of annotations.
Libraries For Image Loading
These are great for securing the development from heavy memory
consumption. They prove to be of great advantage as they decrease the total
memory consumption caused due to the loading of multiple images at the
same time. In any situation in android app development, images are the major
cause of errors like Out of Memory errors.
Take a look at the most popular ones for image loading. They decrease the
complication of cashing and loading images together. They decrease memory
usage and ensure that the app delivers an excellent user experience.
Picasso
It is developed and maintained by Square. It simplifies the process of displaying
images from external locations.

5. It downloads the images and saves the full-size in the cache.
Supports complex image.
It can handle HTTP requests.
Takes care of caching of images.
Not that memory efficient.
Lesser method counts.
Glide
It is highly memory efficient and developers love it for various purposes.
It is basically an image loading library.
Focuses on smooth scrolling.
Loads the images faster.
It supports animated gifs.
Good in reusing the resources.
Automatically releases application resource.
Bigger .jar size.
Libraries For Dependency Injection
For developers, the term Dependency Injection is very common, but for people
from the non-technical background, it can be a little tricky to understand. It is
basically a concept where there is no need for the object to configure its
dependencies.

Should Know!

6. So how does it process?
Well, the dependency is passed in a different object. With this process,
developers can de-couple the classes from the implementation. Because of
this, the code gets loosely coupled, which eventually makes it easier to test
and maintain. Let us study a famous library for dependency injection.
Dagger2
It is very deep and requires a thorough understanding of proper usage.
Dagger2 is an upgraded version of Dagger1, developed by Square and is not
under Google.
It is a completely static library.
It includes Android-specific helpers for Android.
Libraries for View Binding
There is no doubt in the fact that libraries in this department are limited. It
popped up when the need to reduce the boiler-plate code was felt. Let us take
a look at one-
Android Databinding
It is in-built with the Android Support library, and it does not use annotations.
This library greatly reduces the amount of code written in access views.
It is easy to set it up.
Fetches better result with less code.
Provides a variety of functionalities.
These are some of the libraries that everyone must know about. Let us know if
you want to know more about any other of your favorite ones. Till then, stay
hooked.
