a. What is Android Programming?
Android is a Linux-based open-source operating system for mobile devices such as smartphones and tablets. The Open Handset Alliance, led by Google, and other firms collaborated to create Android. This article will teach you the fundamentals of Android programming as well as some advanced concepts in Android application development.
A full set of development tools is included in the Android software development kit (SDK). The Android SDK Platform Tools are a subset of the complete SDK that can be downloaded separately and includes command-line tools like ADB and Fastboot. The Android Debug Bridge (ADB) is a tool that allows you to perform commands on an Android device that is linked to your computer. The Fastboot protocol is used to flash filesystems. Using the Android Native Development Kit, C/C++ code can be compiled to ARM or x86 native code (or their 64-bit equivalents) (NDK).
Since you’ve chosen to begin with Android development, it’s without a doubt one of the best decisions you’ve made. You’ve made a few mistakes on your way to becoming an Android developer, and you’ve learned from them.
So we’d want to share some of the tips and tricks we’ve picked up along the way in the hopes of assisting someone who is just getting started or suffering from Android app development.
On May 17, 2017, Google announced Kotlin as the official programming language for Android development. People are now debating whether to stick with Java or switch to Kotlin. Yes, Kotlin is fantastic, and we highly advocate learning it. However, if you don’t know Kotlin and still want to start developing apps in Java, that’s fine; many people started with Java and continue to code in it. It is not difficult to study Kotlin on the fly.
When you first start designing rudimentary apps for learning purposes, having an architecture pattern won’t matter much, but as you start producing apps for real-world users, you’ll need one. We understand that understanding these patterns is difficult, and you may be tempted to skip them but DO NOT. Simplicity, Testability, and Maintainability are all benefits of having an architecture.
Some of the most well-known are:
- MVC (Model-View-Controller)
- MVVM (Model-View-ViewModel)
- MVP (Model-View-Presenter)
Apart from these architectures, Uncle Bob’s Clean Architecture may be of interest to you. Some businesses even design their own buildings. You may find out more about them by searching on the internet. Clean Architecture is a technique to structure the entire application, whereas MVVM/MVC/MVP is a way to structure the presentation layer.
When you first start out as an Android developer, you should utilise the Android Logger library to debug your code. However, you should try to manually delete Log.d() statements before publishing the programme. When you’re working on a large, complex project, we know that’s a bad idea.
Instead of reinventing the wheel, go to a library that makes your job easier. But that doesn’t imply you should run out and add all of your favourite libraries. Use libraries only when absolutely necessary. There are a few libraries that I use in almost all of my projects simply because they are excellent and save me time while also improving the quality of my apps.
- Glide — for image downloading and caching
- Glide — for image downloading and caching
- Retrofit – Make API Calls Effortlessly
- Gson – It is a tool that converts JSON to POJO and vice versa.
- Data Binding – It is a technique for tying UI components together without using findViewById ()
- LiveData – If there is a change in data, use LiveData to update the view.
The more code you write, the better coder you will be. However, while coding, follow principles, learn about best practices, and see if you can make the code more efficient and shorter. Make an effort to learn design patterns.
Learn to read code in addition to learning to code. You may think what I’m saying is ridiculous, but every developer knows how to read. However, reading, in general, is not the same as reading code to comprehend it.
The user of your app should have no difficulty moving ar ound within it. It should be a smooth transition. Read Google’s Material Design Guidelines for further information. Check out some of the most popular app’s checkout patterns. Obtain input from users.
Your build times will skyrocket as your project becomes more sophisticated. So, to speed up your development time, apply all of the tips and methods available on the internet.
If you come across some complicated material or particular tasks/components that you keep reusing, write them down somewhere, so you don’t have to waste time learning them again in the future. You can write a blog article or make a YouTube video, which will be extremely beneficial to you in the future.
It may be challenging for you to write tests or use testing libraries as a beginning. No problem, start with manual testing and gradually learn to utilize various testing frameworks and write tests. However, before releasing your app on the Play Store, make sure to test all of the scenarios.
Android is very famous as an open-source operating system based on the Linux kernel for smartphones, tablets, and other mobile devices. It was also created for smartwatches and Android TV. Each one has its own user interface. Android is a very popular smartphone operating system. Android OS was created by Android Inc., which was purchased by Google in 2005. Various Android applications, such as games, music players, and cameras, are developed for these cellphones. There are over 3.3 million apps in the Google Play Store. On a worldwide scale, Android still reigns supreme. Android is used by around 75% of the world’s population, whereas iOS is used by 15%. You can learn more about efficient ways of android programming from various android tutorials on different websites.
