As a new developer, or at least new to Android app building, there are more straightforward ways to creating apps instead of trying to learn through trial and error. Developing new skills is important for coders and programmers. Android apps are an extremely useful project to do this with.
What exactly is Android?
Of course, Android is very similar to iOS; however, it’s based on the operating system, Linux. Android is open-sourced, supported by Google, and backed by developers referred to as the Open Handset Alliance. Initially, Android was released in 2007, while the first public device was introduced in 2008.
The skillset of An Android Developer
– Must have knowledge of XML and SQL
– Requires experience in either Kotlin or Java (but preferably both)
– Should know how to use Android Studio and an Android SDK (Software Development Kit)
– Needs to be able to debug, fix issues, and run apps effectively
How to Learn Android App Development
Coders, programmers, and developers looking to learn Android app development should explore the official website of Android, as well as the Material Design website. They are also required to at least learn how to use Kotlin but have basic Java skills too. Java is still the most popular language; however, Kotlin is generally more useful for Android development.
When trying to build an Android app, the IDE, Android Studio, should be installed. This allows developers to construct it easier than with an online coding editor. After the installation, a simple introductory project typically named ‘Hello, World!’ is a good starting point. To complete this, follow these steps:
- Click ‘Create New Project’.
- Find the ‘Select a Project Template’ screen.
- Choose ‘Configure Your Project’ and give the project a name.
- Decide whether to use Kotlin or Java, selecting the appropriate one.
- Once done, click ‘Finish’.
- Run the app.
To run a new Android app on a mobile device, connect it to the computer via USB. Find the ‘Developer Options’ window in Android Studio and allow it to debug the app. In the Debug drop-down menu, select the app. Choose the appropriate device to run it on. By clicking ‘Run’, the text, “Hello, World!”, should appear on the device. This means the app works!
Developers should pay attention to the following:
- Understand the appropriate programming languages—Kotlin and/or Java.
- Get an idea of more advanced features (for future implementation).
- Look at the structure of popular Android apps.
- Learn how to use the appropriate databases.
- Practice debugging apps.
- Gain knowledge of how to optimize apps.
- Utilize third-party libraries.
Android app development has its own process that differs from iOS development. Since they are different, Android requires developers to grasp using certain tools. Kotlin and Java are both important, though Kotlin is considered a must-know language for creating Android apps. Ultimately, being able to understand the elements needed to construct an app is the basis for any app development—iOS or Android. On the other hand, the resources available make the process simpler and easier to understand, so use them.
