Android app development is the process by which new applications are created for the Android devices operating system. Applications are usually developed in Java and/or Kotlin programming language using the Android app software development kit (SDK), but other development environments are also available. Google announced in 2019 to make Kotlin the preferred way of developing android applications.
Kotlin is a cross-platform, statically typed, general-purpose programming language with type inference. Kotlin is designed to interoperate fully with Java, and the JVM version of its standard library depends on the Java Class Library, but type inference allows its syntax to be more concise.
Java is a general-purpose programming language that is class-based, object-oriented, and designed to have as few implementation dependencies as possible.
Android Studio is the official Integrated Development Environment (IDE) for Android app development, based on IntelliJ IDEA. On top of IntelliJ's powerful code editor and developer tools, Android Studio offers even more features that enhance your productivity when building Android apps,
In this section let's dive into world of android app development and create our first app. Learn the basics and start creating some android applications.
Version control is important for all code, files, and assets that multiple team members will collaborate on. Using version control software helps you keep track of changes — and keep every team member working off the latest version.
Notifications are messages that are shown to the user outside of your app's UI. A typical notification consists of a title, a description, and an icon. A notification can also have clickable actions, a quick reply, extendable content, and images.
Graphics are a way developer make their app look attractive and provide better UX/UI. We use advanced graphics in order to building custom views, drawing on a canvas, clipping canvas objects, and using shaders for cool effects.
Animation is a powerful tool for helping users understand a potentially complex and confusing screenful of information. When a single item is updated, animating that change can help the user understand what happened. When many items change, animations can help transition the user from one UI to the next, so that they understand the context and implications of the changes.
Building apps with Google Maps allows you to add features to your app such as satellite imagery, robust UI controls for maps, location tracking, and location markers. You can add value to the standard Google Maps by showing information from your own data set, such as the locations of well-known fishing or climbing areas.
When you implemented the first feature of your first app, you likely
ran the code to verify that it worked as expected. You performed a
test, albeit a manual test. As you continued to add and update
features, you probably also continued to run your code and verify it
works.
Dependency Injection (DI) is a design pattern used to implement
IoC(Inversion of Control). It allows the creation of dependent
objects outside of a class and provides those objects to a class
through different ways. Using DI, we move the creation and binding
of the dependent objects outside of the class that depends on them.
By allowing users to log in and create an identity within your app, you can provide them with more ways to interact with the app. With personalized accounts, users can customize their in-app experience, engage with other users, and have their data persisted and transferred if they're using the app on another device
Now that you know how to make interactive apps lets dive into more advanced Application development. Now we should learn about how to handle touch input, gestures, using camera inside your application, multi-threading and Android Jetpack.
Android App development is a really vast field with lots of variation available. To go further into learning you can go with following resources. Meanwhile, you can start working on projects and keep learning side by side. Refer to these:
