Introduction
Starting at mid 2016, there are well over a billion people effectively utilizing Android, a Unix-like versatile working framework that sudden spikes in demand for telephones, tablets, shrewd TVs, savvy watches, and a huge number of different gadgets. Albeit created and kept up by Google, it’s free and open source programming that can be utilized and modified by anyone. Thus, Android gadgets are produced by a few significant gadget fabricates, as Samsung, LG, Sony, and HTC.
One of the essential factors that drives Android’s prosperity is Google Play, an Android application dissemination stage clients can use to download and introduce applications on their gadgets. With over a million applications and billions of downloads, Google Play is bigger and sees more traffic than comparative stages for iOS and Windows 10.
I’m certain you are currently starting to think about how you can turn into an application designer and money in on the notoriety of Android. In this article, I’m going to give you a superior perspective on what Android application development involves today.
Do you think that its simpler to learn with video? Why not look at our course:

Developing Native Android Apps
There are a wide range of ways to deal with Android application improvement. In this arrangement, in any case, we’ll be focussing just on the local methodology since local applications offer prevalent execution, run with negligible overhead, and are fit for utilizing the Android working framework’s abilities.
Local Android applications are created utilizing the Java programming language, and, on gadgets running Android 5.0 or higher, utilize an oversaw runtime called Android Runtime (ART) as a matter of course. To make such applications, most designers decide to utilize Android Studio, the official Android IDE created by Google. Android Studio is free and runs on Windows, OS X, and most Linux dispersions.
Android Studio 1.5.1, the current stable delivery, has countless features to rearrange all parts of Android application development, such as an incredible code proofreader, visual format and subject editors, vector and picture resource studios, and the sky is the limit from there. Android Studio 2.0, which is still just accessible as a see discharge, has further developed highlights like moment run and a GPU profiler to additionally improve the application advancement experience.
Android Studio additionally accompanies a sensible emulator you can utilize in the event that you don’t possess an Android gadget. Since framework pictures for it are uninhibitedly accessible, you can download and run any adaptation of Android on it.
Challenges Android App Developers Face
Developing an Android application that runs well on one explicit Android telephone or tablet is simple. Developing one that runs well on all Android gadgets, be that as it may, can be staggeringly hard as a result of the huge contrasts in working framework variants, screen sizes, and gadget capacities.
Supporting Older Android Versions
In contrast to Apple’s iOS gadgets, most Android gadgets once in a while get programming refreshes, if by any means. Marshmallow, the most recent rendition of Android, runs on under 1.5% of all Android gadgets today, despite the fact that it was delivered a while prior.
This implies, in the event that you choose to build up an application, you should bolster more seasoned renditions of Android, as KitKat and Lollipop. In addition, if your essential client base is from creating nations, supporting more seasoned forms right back to Android Gingerbread, is suggested. Doing as such, be that as it may, is normally simple, because of the Android Support Library, yet additionally various outsider open source libraries.
Handling Different Screen Sizes and Densities
In the beginning of Android, there were just few gadgets that could run Android and practically every one of them were telephones. Throughout the years, be that as it may, with increasingly more gadget manufacturers embracing the stage, gadget screen sizes and pixel densities started to differ uncontrollably.
With the arrival of Android Honeycomb, Android additionally began supporting huge screen gadgets, for example, tablets and keen TVs. Subsequently, designers today are relied upon to utilize various picture sizes and formats to help every one of those various screens.
While making the formats is as yet a fairly tedious procedure, overseeing distinctive picture sizes has become simpler gratitude to Vector Asset Studio.
Handling Hardware Sensor Availability
Just a couple of top of the line gadgets have all the equipment sensors the Android SDK underpins. Subsequently, designers are required to compose applications that can decide the equipment abilities of a gadget at runtime, and corrupt nimbly if conceivable.
The Android SDK (Software Development Kit) has a Sensor Framework to disentangle this errand. On the other hand, engineers can keep clients from introducing applications on gadgets missing the necessary equipment utilizing Google Play channels.
Recent Trends
The Android stage is continually advancing and application designers must stay aware of ongoing patterns to have the option to develop applications that live to client desires.
Material Design
Material plan is an assortment of very much idea out structure rules you can follow to fabricate applications whose look and feel coordinates the local look and feel of Android Lollipop and Marshmallow. Attributable to its effortlessness and present day looks, material structure appreciates a great deal of fame among the two engineers and creators.
Android Wear
Android Wear smartwatches are turning out to be progressively famous in light of the fact that the most recent models are better looking and have highlights, for example, as good as ever motions and watch faces that make them more enjoyable to utilize. Subsequently, an ever increasing number of engineers are utilizing the Wear API in their applications to ensure that their applications can communicate with wearable gadgets.
Publishing Android Apps
When you’ve built up an application, you can distribute it on the web with the goal that individuals everywhere throughout the world can download and utilize it. There are heaps of Android application commercial centers you can distribute your application on, however the one most famous today is Google Play since it comes pre-introduced on most Android gadgets.
To have the option to distribute your application on Google Play, you should pay an enlistment charge of $25 and make a designer account on it. When you have a record, distributing an application includes transferring its APK—a compacted bundle document that you produce utilizing Android Studio—alongside a couple screen captures and giving subtleties, for example, the application’s name and depiction.
In the wake of presenting all the subtleties, you should sit tight for a couple of hours for the application to go live. In mid 2015, Google Play acquainted an application endorsement process with ensure that distributed applications hold fast to Google’s substance approaches.
