Android Development with Kotlin Classroom Course

You will start with understanding the overall picture of Android app development and get hands-on experience by building your first Android app with Kotlin. The journey continues through testing and debugging techniques, UI customization, and high-quality UX creation using AndroidX libraries. Each course offers step-by-step guidance and practical examples to equip you with the skills necessary to build robust, scalable, and user-friendly Android applications. Once a view has been defined in a layout file, you can access it in your Kotlin code using the findViewById() method. This method takes an ID that corresponds to the ID defined in the XML layout file. You can then use the view object to set its properties, such as its text or visibility.

• The journey continues through testing and debugging techniques, UI customization, and high-quality UX creation using AndroidX libraries.
• Meet the team and learn what you’ll need to begin developing Android apps with Jetpack Compose.
• This intelligent type handling makes Kotlin Android Development significantly more fluid and less error-prone.
• It’s useful when you write code for your project because you can easily access the files you will be working on in your app.
• When you build Android apps, you’ll need to create layouts using XML and the visual designer, and then define how those elements work in the corresponding Kotlin or Java code.
• This allows for better code completion, type checking, and error detection.
