Android development is a software creation process that focuses on applications, better known as apps, that are compatible with devices running the Android operating system (OS). Because Android is an open-source project, developers have easy access to the Android software development kit (SDK). Many use this kit in conjunction with Kotlin, Java, and C++ programming languages to make their apps. The Android SDK tools compile your code along with any data and resource files into an APK, or Android package, which is an archive file that uses an .apk suffix. One APK file contains all Android app contents used by devices to install your app. When the app is complete and ready for release, Android developers can upload their apps to the Google Play Store for users to download.
Creating the View Model Class4:25
In this lesson, we created the View Model class.
The tools you will use for Android development depend on how you would like to focus your career as an Android developer. If you plan on focusing on native Android app development, you should know one or more of three programming languages: Java, Kotlin, and C++. Java and Kotlin are popular with a number of organizations that build their app natively. C++ is the popular choice amongst developers who build high-performance games or plan on doing entry-level SDK work. Some employers seek out Android developers that can create multiple platforms at the same time using programming frameworks like Flutter or React Native. If you are working with Flutter, you will also need to know Dart. If you are working with React Native, you will most likely also need JavaScript programming knowledge.
The Application Design-18:07
In this lesson, we designed the Main activity.
With over 2.5 billion active Android users globally, Android development is a valuable skill that can help you enhance your career. Android development skills are in-demand around the world with various organizations across a broad range of industries. When these organizations build Android apps natively, the top three programming languages are typically Java, Kotlin, and C++. You can also look for a job in Android development that uses cross-platform solutions like Flutter or React Native. Whether you're inspired to add a new language to your repertoire or prepare for an interview, you can find a ton of online resources on sites like OAK Academy to keep your Android skills well-rounded.
The Application Design-28:04
In this lesson, we designed the Add Image activity.
If you are building new Android apps, Kotlin is better suited because it is the recommended programming language for Android. If you are a first-time programmer, Kotlin android is also a better choice as it has safety features and concise syntax that will help you focus on learning core program fundamentals. You should note that in some cases, employers may seek out Android developers that have Java programming skills. For example, if you plan on joining an organization that already has an Android app, they may already be using Java. If they already have an app written in Java, it is unlikely they will want to redesign the app in a different language, such as android kotlin. Therefore, you should look at the job requirements to see if the job posting you are interested in lists Java as a required skill.
The Application Design-34:23
In this lesson, we designed the Update Image activity. android app development
Creating The Adapter Class in android7:03

In this lesson, we explained how we can delete the data we have saved in the database. We did this deletion by swiping any data displayed on the recycler view with a finger gesture.

This course is built to help beginners to start making applications in android studio and android application development or android app design.
