Complete Android Development with Kotlin Masterclass

install android studio on windows by verifying system requirements, downloading the installer, and completing the default setup with sdk, jdk, and theme options.

Install android studio on mac by checking system requirements, downloading the official package, installing from the dmg, choosing standard setup, and configuring the SDK and JDK for first use.

Create an Android Studio project by selecting a phone and tablet empty activity template, then configure the project name, package name, save location, language, and minimum SDK.

Create and configure an Android virtual device using the AVD manager, download a compatible system image, and run a hello world app on the emulator to test Android apps.

Learn to run your Android app on a real device by connecting via USB, installing the Windows USB driver, and enabling developer options and USB debugging in the IDE.

A relative layout is a view group that positions child views relative to the parent or to each other. Place views on top, bottom, and left within the relative layout.

Explore Android Studio's layout editor, insert an image view into a relative layout, center it, create and reference a string resource for content description, and preview on multiple devices.

Explore the core Android Studio topics: project packaging and naming, relative layout positioning, and resource file management (strings, colors, layouts), plus margin and padding concepts.

Import a completed android studio project from zip or github, clone via git, open the existing project, and explore the main activity and layout.

Tackle practical challenges to apply what you’ve learned, including building a happy birthday card layout with a centered image and a bottom-right text view.

Explore how Android scaling handles diverse screen sizes and pixel densities with resolution independent units, using dp for margins, padding, and image sizes, and asp for text sizes.

Explore how a pixel, the picture element, forms images on devices, and how higher pixel counts and device resolution boost image crispiness, with Android units guiding image sizing.

Explore pixel density and DPI to understand how image and text crispness varies across Android screens, and how logical densities with the baseline 160 DPI enable density independent pixels.

Understand density independent pixels (dp) and scalable pixels (sp) to keep ui elements and text sizing consistent across devices by mapping dp to physical pixels according to screen density.

Explore how pixel density and density-independent pixels shape scalable Android visuals, categorize devices by dpi, and prepare icons with dp and sp for consistency across screens.

Preview the email app section with title and description inputs and a send button. Create a custom icon with Image Assets Studio and study linear layout and styles.

create a custom launcher icon using image asset studio in Android Studio, covering adaptive and legacy icons, foreground and background layers, and placing icons in mipmap folders.

Explore how linear layout uses a view group to arrange views in vertical or horizontal orientation, and control space with layout_weight for the mail app UI.

Create a mail app user interface in Android Studio using a vertical linear layout with three edit texts for title, to, and message, plus a send button.

Explore styling in Android by extracting common attributes into a reusable style. Apply the style to edit texts using a styles file in values to reduce boilerplate.

Discover how themes in Android apply a global style to an entire app, activity, or view hierarchy, defining color primary, color primary dark, and color accent through the manifest theme.

Learn to manage image assets and icons in Android Studio, design with linear layout, use edit text and bottom view, extract reusable styles, apply app theme and colors, review manifest.

Create a Kotlin dice rolling app that generates a random number to update a text view and display dice images. Learn user interface, when statements, density drawables, and XML namespaces.

design the dice app UI in Android with a relative layout, display a centered number from a generated random roll, and provide a bottom roll button to update dice images.

Create the dice app functionality in the main activity. Use findViewById to access views, and roll a dice to display a 1–6 number in a text view when clicked.

Improve app efficiency by reducing findViewById calls and storing view references in fields, using nullable and lateinit variables, and safely initializing after layout setup.

Learn to import dice images for all densities, display them with image views, and roll using a when statement and random numbers in a Kotlin Android app.

Demonstrate building a two-dice interface in Android using a horizontal linear layout, with padding, margins, refactoring drawable names, and distinct images driven by random numbers.

Explore how to define integer and floating point variables in Kotlin for Android Studio, perform arithmetic operations (add, subtract, multiply, divide, remainder), and observe operator precedence with examples.

Name variables with camel case and lowercase beginnings to improve readability. Emphasize descriptive names and avoid starting with digits, spaces, or reserved keywords.

Learn the Kotlin variable types var and val in Android development: mutable var allows multiple reassignments, while immutable val initializes once, with IDE warnings guiding immutability.

Explore boolean data types by creating boolean variables such as isRaining and isSunny, and apply them to decision making and control flow in Kotlin Android development.

Explore creating and using arrays in Kotlin, including integer, string, and mixed type arrays, accessing elements by zero-based indices, and iterating with loops.

Explore Kotlin data types such as integers, floating points, booleans, strings, and characters, and learn about arrays. Define variables with var and val and apply an ecomil naming convention.

Explore how comparison operators work in Kotlin for Android: less than, greater than, equal, not equal, and their use with variables and boolean results, with simple logcat examples.

Learn to use logical operators in Android development with Kotlin by combining comparison operators with and and or, evaluating boolean expressions, and applying them in control flows.
