App development becomes more popular day by day. Cause, nowadays many people use an android based smartphone than the computer. In this article, I will discuss app development guideline for beginners. So, let’s start.
Android is a java based OS, which is employed on phones, tablets, smart TVs, smartwatches and more. While Google is developing and deploying it, it is free and open-source software that anyone can switch to. Android devices are manufactured by several major device manufacturers, like Samsung, LG, Sony and HTC. The key to the success of Android is Google Play, where Android apps are marketed and users can download and install them on their device. In terms of the Law app and the billions of downloads, Google Play is much bigger than any other platform like iOS and Windows 7, and its traffic is higher than that.
Native Android App Development:
There are many ways for Android application development. The native way is one of them. The functionality of native apps is high, runs with the lowest resources and can utilize the full functionality of the Android operating system. Native Android apps are developed in the Java programming language and can use Managed Runtime and Android Runtime on devices that run Android 4.1 or higher. Most developers use the official Android IDE Android Studio developed by Google to create such an app. Android Studio is free software and it runs on Windows, OSX and almost all Linux distributions.
There are many features in the current stable release, namely, Android Studio 4.1.1, which will make it easier for Android Studio also has a realistic emulator that you can use if you don’t have an Android device. Since its system images are available for free, you can easily download any version of Android by using it.
All Android app development like a strong code editor, visual layout and theme editor, vector and image asset studio and more. Android Studio 2.0, which is still available as a preview release, offers many advanced features such as instant run and GPU profiler, making app development even more sophisticated.
Android Studio also has an emulator which you can use it if you don’t have an Android device. Since its system images are available for free, you can easily download any version of Android by using it.
Challenges for Android App Developers:
It’s much easier to build an Android app that runs on a specific Android phone or tablet. However, it can be not very easy to build an app that works well on all Android devices. This is because of the wide variations in the operating system, different screen sizes and different functionality of the devices.
Support for older Android versions:
Repeated software updates like Apple’s iOS device do not come for most Android devices, that is to say. Marshmallow, the latest version of Android, will only be available on only 5.5% of Android devices today, though it was released several years ago. This means that if you would like to create an app, you’ll also got to believe older versions of Android, like KitKat and Lollipop. In addition, if the main part of your user is from developing countries, then it would be better to provide support from that old version of Android Gingerbread. While this is pretty easy to do, there is an Android support library, and third party support from many open source libraries will also be available.
The size and density of the screen:
At the beginning of Android, only a few devices were running Android, and almost all of them were phones. Recently many new device makers have come to the Android platform, which has resulted in wide variations in device screen size and pixel density.
Hardware sensor availability:
There are hardware sensors that support Android SDs only on a few high-end devices. Because of this, developers will need to write an app that will understand what hardware functionality is supported during the run, and make it possible to work with the app as needed.
Android wearable smartwatches are getting increasingly popular. This is often because the newest models have many exciting features and features, like new and improved gestures and watch faces. Which is why it’s fun to use them. As a result, more and more developers are gradually using the Wire APIs in their apps in order that their apps can communicate with wearable devices.
How to learn app development:
You can learn app development in many ways. You can learn it in two steps. 1st step is, you can admit an institution where you will learn app development properly. And you will always get support from them. 2nd step is you can buy the paid app development course and practice it at home. Without this two-step, you can also learn app development by Google and YouTube. There is a huge amount of resources and tutorial about app development guideline. You can learn free from here.
I this article I have tried to give some basic guideline for app development. If you want to be an app developer you should practice more and more. Then you will succeed in this sector.
