Android OS is leading the global market share with 71.59% with improved stability, maturity, and technological innovations.
The captivating statistics showcase how much people are using Android apps to get their needs served. It creates a gala opportunity for businesses to catch maximum eyeballs by building Android apps. The businesses partner with android development companies to move ahead with Android app development.
Android app development is a time-consuming, complex, and tedious process because of device fragmentation issues. The app development companies preferably use Kotlin as opposed to Java to get Android apps developed in reduced time. When we surveyed the team of Android developers, they stated it’s not enough to accelerate app development.
Android OS provides a set of libraries that developers leverage to meet different Android app development requirements of the businesses. Let’s understand Android libraries in a nutshell.

What are Android libraries?
The Android libraries are pre-defined blocks of code that come with a pre-designed interface. The libraries include documentation and message template that help the user know how to implement the libraries. The Android libraries enable Android development in reduced efforts and time as they don’t require developers to build them from scratch. They act as a readymade tool to build the functionality effortlessly.
Which libraries enable Android development in reduced time?
· Reactive programming libraries
Reactive programming libraries help in seamlessly transferring data from one component to another component. It’s mostly used in Android applications where data transfer is required from source to subscribers which helps in asynchronous task handling. The library that serves the reactive programming purpose is RxJava2.
RxJava2 is a perfect fit for building reactive applications. The Android developers prefer leveraging observable sequence for creating event-based and asynchronous programs as it highlights the errors quickly, provides a unique way for concurrent operations declaration, and simplifies the async operations chaining process.
· Drawing libraries
Drawing libraries allow the developers to add creative capabilities to the Android applications. The graphic libraries that make the app stand out and are favored by the developers are-
o Holography library
Not so old library is highly leveraged by Android developers to engineer the graphs and charts effortlessly. It comprises- the LineGraph view, BarGraph view, MultiSeriesDonutGraph view, and PieGraph view for classic graphics creation.
The library meets the needs of animation during chart drawing, facilitates space between split charts, add click effects, alpha animation on touch, and introduces description text labels. It ensures data won’t be lost when the animation is too fast.
The drawing library preferred by developers for different types of chart creation is also available for ios app development. It facilitates candlestick charts, bubble charts, radar charts, pie charts, horizontal bar charts, line charts, animations, and dragging.
The drawing library enables working with canvas using objects in place of the method to create a custom underline of Textview.
· Image loading libraries
Android apps mostly suffer from performance or resolution issues because of the loading of several images simultaneously. The libraries help in better handling images without memory issues are-
The popular image loader managed by Bumptech is highly recommended by Google for efficient media management. It encompasses memory caching, media decoding, and resource pooling within a simple interface that supports obtaining, decoding, and showcasing video stills and animated GIFs. Glide also works wonderfully in fetching, changing size, and displaying a remote image.
The image downloading and caching library adds visual flair to the Android applications flawlessly with automatic memory and disk caching, complex image transformation with the least memory usage, and handles imageview recycling in just one line of code.
It also features adapter downloads, image transformations, place holders, resource loading, debug indicators, and more that ensure hassle-free image loading.
· UI component libraries
Irrespective of technological advancements, the users show zero tolerance for flawed UI development. UI component libraries ensure zero errors would occur in the Android app’s interface.
o Gravity view
The Android UI library works on Android 3.0 and later versions. It has got popularity with gravity view after the “Fynd” app development. behind the scene, the library uses the Android device’s motion sensors to allow users better view the product with the device tilting or a certain degree of rotation. If the device is a non-gyroscope, the accelerometer sensors are used to incorporate the gravity view in the application.
o Panel layout
The UI library uses ConatraintLayout to create a panel that’s resized and floatable using content (Tools, shapes, and colors). This library is the result of the iOS UI framework- PanelKit. It’s licensed under a 2-clause BSD license.
· Testing libraries
Testing is a part of mobile app development that can’t be skipped at any cost before launching the app in the market. Here are some testing libraries that ensure flawless delivery of the Android apps.
It’s a testing framework that helps developers build UI tests for Android apps. The test written by developers is run on emulators and real devices giving a view of real users. Adding dependencies to the app module is all-important for using the Espresso library.
It’s one of the unit testing libraries that handles resource loading inflation, views, and others. It simulates the Android SDK for app testing that alleviates mocking framework needs. Also, adding dependency and creating a sample test class to use the testing library.
Android libraries are a boon to the Android ecosystem that enables Android developers to build quality apps in reduced time and effort from scratch. With the increasing trend for Android app development, it’s essential to know the libraries that make Android development seamless.
Before selecting an Android library, the developers must check a couple of things such as license authenticity, author’s reliability, popularity, reliability, recommendations, and code quality to ensure it may not pose any problem at a later stage. Don’t get confused with fancy options, instead, choose the library that makes Android app development a breeze.
