Android, a Unix-like mobile os that runs across smartphones, tablets, smart TVs, wearable technology, and a variety of other devices, was being used by well over a billion people as of the start of 2016. It is free and open source that anyone who can use and alter, despite being created and maintained by Google. As a consequence, many large device manufacturers, including Samsung, LG, Sony, and HTC, produce Android-based smartphones.

The process of creating Android applications can take many different forms. But in this series, we’ll only be concentrating on native apps because they provide the highest performance, incur the least amount of overhead, and can utilise the features of the Android operating system to the fullest extent.Java is the coding language of choice for creating native Android apps, which by default use the controlled environment known as Android Runtime (ART) on devices running Android 5.0 or higher. The majority of developers decide to use Android Studio, the official Android IDE created by Google, to create such apps. Windows, OS X, and the majority of Linux editions all support Android Studio, which is free.

It is simple to create an Android app that functions effectively on a particular Android phone or tablet. However, due to the wide variations in operating system versions, screen sizes, and device capabilities, creating one that functions properly on all Android devices can be exceedingly challenging.

Usually Android smartphones receive very little, if any, software upgrades, in contrast to Apple’s iOS devices. Even though Marshmallow, the most recent version of Android, was introduced a few months ago, or less 1.5% of all Android phones are currently running it. It means that if you choose to develop an app, it must support earlier Android releases like KitKat and Lollipop. Additionally, it’s advised to support earlier ones all the way to the back to Android Gingerbread if your target user base is primarily from underdeveloped nations. But doing so would be typically simple because of the Android Support Libraries as well as several other open source libraries from other sources.

When Android first came out, there were very few devices that might run it, and practically all of them have been phones. But as more device manufacturers adopted the platform over time, the range of device bigger screens & pixel density grew significantly. Android started supporting large screen gadgets like tablets and smart TVs with the introduction of Android Honeycomb. In order to serve all those various displays, programmers are now obliged to use a variety of picture formats and styles.

To create apps which stay true to user expectations, application developers should stay current with current developments as the Android operating system is always growing.

A set of thoughtful design principles known as “Ui Elements” may be used to create apps that have the same aesthetic appeal as Android Lollipop and Marshmallow’s native interface. Material design is very well-liked by both engineers and designers because to its simplicity and modern appearance.

Android Wear smartwatch are gaining more and more popular since the most recent models have superior looks and features like updated gestures and entertaining watch faces. As a result, an increasing number of developers are including the Wear API in their apps to ensure that they can communicate with smart watches.

After developing an app, you may publish it online for download and usage by anybody in the globe. There are many Android app stores where you may publish your app, but Google Play is now the most well as it comes with pre on the majority of Android phones. You must register an account on Google Play and pay a $25 registration fee before you can publish your app there. Once you’ve created an account, releasing an app entails uploading the app’s APK (a compressed package file you generate utilizing Android Studio), a few images, and information like the title and descriptions.

Nothing compares to the adrenaline you get when your app live on Google Play if you’re developing Android apps. But why not commercialise the app if you spent a lot of time and work creating it? Many individuals today create Android apps for a living, and if your apps are great sufficient, you may too. An application can be made money in a variety of ways. Here

seem to be three well-liked methods, which all make use of Google services:

Sell It on Play Store: Premium apps can be published by programmers on Google Play in the majority of nations. A user can only download a premium app after purchasing it, in contrast to free apps. Because you don’t need to develop any code for it, this is the simplest approach to monetise an app.
Display Adverts: You can show banner or interstitial ads in your app by utilising Google’s Mobile Ads SDK. With this configuration, you are typically compensated each time a user views or clicks an advertisement.
Sell Items Within the App: You can provide digital goods for sale to mobile apps by utilising an In Billing API. You may, for instance, offer your app free before adding a tiny fee.

I believe you have a basic idea of what App entails in the present day. Despite all of its difficulties, creating Android apps is quite simple because to the vast online instructions and the ever-improving developer tools. You will learn how to set up Android Studio on your computer in the following paragraph of this series, which will be your initial step toward being an Android app programmer.
