Thor had Mjölnir and Sherlock Holmes had his mind, however what do Android application engineers have? – I'll advise you, it's the unfathomable libraries. 

To sum things up, Android structures and libraries (or only libraries by and large), are a bunch of executions of conduct that are sent in programming dialects and have an all around characterized interface. 

These libraries by and large incorporate documentation, arrangement information, message layouts, help information, pre-composed code and subroutines, values, classes, to give some examples. 

One of the significant purposes behind utilizing these libraries is to speed up the advancement cycle, i.e., build up a dumbfounding application with no superfluous or extra endeavors. These libraries furnish engineers with essential pre-composed codes and other significant components that can be utilized in a flash instead of playing out these errands without any preparation. 

Along these lines, in the event that you have quite recently begun your profession in Android applications creation and need to think about famous libraries that are a go-to instrument of pretty much every best Android application advancement organization, at that point this article is the thing that you required. 

Here are the 15 best Android libraries for designers. 

Reliance Injector Library 

Before we move onto the rundown of best and most recent Android libraries 2020 for Dependency Injector, for what reason don't we comprehend what Dependency Injector is? 

1. Knife 2 

An incredible aspect regarding Dagger 2 is that it significantly depends on utilizing Java explanation processors alongside arrange time to appraise and examine conditions. Despite what might be expected, other Java reliance infusion libraries experience the ill effects of restrictions, for example, depending on XML, causing execution punishments during startup, or confronting approving reliance issues at run-time. 

Another bit of leeway of Dagger 2 is that it improves on admittance to shared examples. For instance, when you pronounce in Dagger the singleton occurrences like MyTwitterApiClient or SharedPreferences, you can without much of a stretch announce fields with a straightforward @Inject explanation: 

Systems administration 

Here are the apparatuses that you need for building up any sort of organization correspondence inside the Android application. 

2. Retrofit 

Retrofit is a sort safe REST customer for Android and Java, shrewdly planning an API into a customer interface with the assistance of comments. Already, in the event that you needed to make an organization demand, you expected to execute an Async task class and afterward use HttpsUrlConnection to get information, something that was not ideal when managing APIs returning huge information. This is currently settled by Retrofit. 

One can easily control endpoints and headers, add a solicitation body and inquiry boundaries, and select solicitation techniques – all with only comments in Retrofit. Additionally, this Android library likewise deals with parsing to POJOs by utilizing converters. 

Start by adding reliance to your applications build.gradle document – 

Subsequent to adding the reliance to your application build.gradle document, you should add a reliance for converters that you mean to utilize. 

Picture stacking libraries are a knight in sparkling shield battling with the issue of "out memory mistakes" in Android applications brought about by stacking different pictures all at once. How about we take a gander at the best Android libraries choices out there in this classification. 

3. Picasso 

Kept up by Square, Picasso is a trusted and broadly utilized Android picture library. Picasso professes to take into account bother free picture stacking in the application—regularly in one line of code. 

A portion of the traps that Picasso deals with incorporate taking care of ImageView reusing and downloading cancelation in a connector, encouraging complex picture changes utilizing insignificant memory, programmed memory, and reserving. 

Extra highlights that settles on Picasso a well known decision among Android application designers are – 

Picasso consequently distinguishes connector re-use and the recently dropped download. 

It effectively and viably changes pictures to make them fit better into formats and decrease memory size. 

For further developed impacts, one can determine custom changes. 

4. Float 

Float is one more lauded picture loader and outstanding amongst other new Android libraries for designers, overseen by Bumptech. This, yet it is likewise suggested straight by Google. 

Skim not just gives vivified GIF uphold while taking care of picture stacking and reserving yet additionally helps in bringing, translating, showing video calls, pictures, and these GIFs. It additionally incorporates an adaptable API permitting designers and developers to connect any organization stack, as its default stack is HttpUrlConnection. 

This library principally targets making the looking over interaction for any rundown of pictures really smooth. All the more thus, it is additionally compelling on the off chance that you need to get, resize, or even presentation a distant picture. 

Examining 

To incorporate examining highlights while creating custom Android applications and increment their usefulness level, designers lean toward the beneath referenced libraries. 

5. Zxing 

Abbreviation for 'Zebra Crossing', ZXing is a standardized tag picture preparing Android library that is executed in Java, with ports to other programming dialects. This library likewise has uphold for the 1D item, 1D mechanical, and 2D standardized identifications. 

Google likewise utilizes ZXing to make a great many scanner tags indexable on the web. It likewise frames the premise of Android's Barcode Scanner application and is incorporated into Google Book Search and Google Product. 

6. CAMView 

This is a powerful option in contrast to the ZXing standardized identification scanner. It is an Android camera simple access library with an inserted QR scanner which depends on ZXing. 

CamView library has a bunch of segments (sees in basic words) which are set to be put to your format documents, permitting designers and giving prompt admittance to-

Checking standardized tags with the assistance of ZXing's inherent translating motor 

To play out your own camera live information handling 

View Binding 

The requirement for see restricting libraries initially surfaced when the need to lessen the standard code when allotting perspectives to factors emerged. Truly, the quantity of libraries worth referencing for this design is numbered and two of the most noticeable of them are – 

7. ButterKnife 

Created by Jake Wharton, ButterKnife is a prestigious view restricting library encouraging in allocating ids to sees easily, consequently maintaining a strategic distance from the abundance of findViewByld. The assertion "Butterknife resembles Dagger just endlessly less sharp" connotes that view restricting is kind of reliance infusion. The lone contrast is that in ButterKnife comments are utilized to produce standard code. 

The code beneath shows that ButterKnife wipes out the requirement for things like onClick and onTouch while supplanting them with auto infused code. 

8. Android Databinding 

In-worked to the Android Support Library, the Android Databinding library requires the least of Android Studio Version 1.3 to work. In contrast to ButterKnife, this view-restricting library for Android doesn't utilize comments. It permits you to tie UI parts in the designs to information sources in the application with the assistance of explanatory arrangement rather than automatically. 

Here designs are characterized in exercises with code that needs UI structure techniques, i.e., take a gander at the code underneath. It calls findViewById() to discover TextView gadget while restricting it to userName property of the variable viewModel. 

Investigating 

Very nearly a crucial advance in the application improvement measure, troubleshooting an application before its last delivery is pretty much significant. For this intention, how about we view some valuable libraries.

9.  Stetho

Stetho claims to be a “sophisticated debug bridge for Android applications”. The use of this library is not limited to just Network inspection, Database inspection, JavaScript Console, etc. but developers use it to have access to the Chrome Developer Tools features that are natively part of the Chrome desktop browser. Moreover, developers can choose to enable the optional dump app tool offering a powerful command-line interface to application internals.

Reactive Programming

In Reactive programming, data is released from a component (a source if you will) to the other component known as Subscriber, assisting in handling asynchronous tasks efficaciously. So in short, these libraries help with transferring data from source to subscribers. Some of the widely used Android app development libraries for this purpose are –

10.  RxJava2

If you are looking for a library that helps you in implementing reactive programming (create reactive applications), then RxJava is an ideal choice for you. It is officially described as “a library for composing asynchronous and event-based programs by using observable sequences”. 

This library is considered unbeatable by Android app developers because it simplifies the process to chain async operations, opens a more explicit way to declare how concurrent operations should work, is able to highlight errors sooner than other libraries, among other things.

Drawing

There are hundreds of new libraries being developed every day, but very few are able to impress developers and prove potent. Here are some Android apps graphic libraries that have stood apart from the crowd. 

11.  MPAndroidChart

MPAndroidChart is an impeccable Android chart/graph view library. It supports radar, line, bar, bubble, pie, candlestick charts along with scaling, animations, and dragging.

If you are looking for its iOS counterpart then, Charts is the one for iOS app development.

12.  Holo Graph library

It is another new graphic library which is continuously becoming a favorite of many Android app development companies. This library is ideal for adding impeccably designed graphs and charts into Android applications. It includes – 

LineGraph view (which looks something like this) –

  • BarGraph View
  • PieGraph View
  • MultiSeriesDonutGraph View
  • UI Components

User Interface is a prominent and with no-space-for-negligence aspect of Android app development. New innovations and advances have surfaced over the years in the UI domain, one of which is Gravity View. 

13.  Gravity View

A very ‘in’ concept in the market is the gravity view. This is a library that is used for image tilting using sensors. Gravity View library’s goal is to utilize the motion sensors of Android devices, allowing users to perform certain functions by rotating their device.

This Android UI library was first used in the famous application “Fynd” and has continued to become a favorite of many to date. You need to be operating Android 3.0 and higher in order to use this library. Moreover, if you need to use it for non-gyroscope devices, then you can do so with the help of the Accelerometer sensor.

Testing

Testing your project is a way to become sure of the competence and efficacy of your mobile app. You can use these libraries to test your mobile app before you ship it to the market.

14.  Espresso

A part of the Android testing support library, Espresso is evidently a test framework that enables developers to build user interface tests for Android applications. Implying that this library lets you write tests and check whether the text of a TextView is similar to another text or not. It imparts the impression of a real user using the app, running both on real devices as well as emulators.

In order to use this library, you are required to add dependencies to the app module build.gradle file.

Once you have done this, you can set the instrumentation runner and sync the Gradle files, followed by creating a rest file –

15.  Robolectric

Robolectric is another unparalleled unit testing library. What this library does is that it handles inflation of resource loading, views, including other things. It makes the tests created in the library more efficacious and potent in performing functions that real devices with  Android framework dependencies perform. In a sense, Robolectric simulates the Android SDK for the tests, eliminating the need for additional mocking frameworks like Mockito.

Now again, you need to add the dependency in your app’s build.gradle file, followed by creating a sample test class –

These libraries have made it to this list based on the popular recommendation of the Android developers. Their features, functions, and performance together emit excellence in their niche of purpose.
