    What is Android?

    • Android is an open-source, Linux-based operating system.
    • It runs on devices like smartphones and tablets.
    • It's also used in other markets such as TVs and wearables.
    • Developed by the Open Handset Alliance, led by Google.
    • Supports multitasking, allowing users to run multiple apps simultaneously.

    Why Android?

    • Market Dominance: Android has a large and growing user base.
    • Global Reach: Access to billions of users via the Google Play Store.
    • Open Source: The Linux kernel provides flexibility for developers. Open-source code encourages innovation and customization.
    • Versatile Development: Supports languages like Java, Kotlin, and C++. Cross-platform frameworks like Flutter. Extensive libraries and APIs for modern features (e.g., AI/ML). It has seamless integration with Google services.

    Android History and API Level

    • API Level is a unique integer value for Android framework API revisions.
    • The framework API consists of core packages, XML elements, attributes for a manifest file, attributes for declaring and accessing resources, Intents, and permissions for apps.
    • Newer API levels can access behaviors or features not available in older levels.

    Android Studio IDE

    • Android Studio is Google's official IDE for developing Android applications.
    • It uses Java and is built on JetBrains' IntelliJ IDEA platform.

    Android Studio - File Structure

    • AndroidManifest.xml: Contains essential app information (components, permissions, configuration).
    • Java Files: Contains the application's code logic, activities, services, etc.
    • Layout Files: Define the UI structure (XML format).
    • Drawable Files: Contain UI graphical resources (images icons).
    • Mipmap Files: Contain app launcher icons in various resolutions.
    • Strings Files: Store text for the app (for easy localization).
    • Build Gradle Files: Contains the build configuration (dependencies, SDK versions, etc).
    • The files are structured in projects for development.

    Code Examples

    • Examples of XML layouts, code within Java files and strings.xml are included in the documentation.

    Android Components

    • Activity: Represents a single screen with a UI. Controls the UI and user interactions.
    • Service: Runs in the background without a UI (e.g., downloading).
    • Content Provider: Manages shared data between apps (e.g., accessing contacts).
    • Intent: Facilitates communications between components. Explicit Intents target specific components while Implicit Intents are general, allowing the system to decide.
    • Fragment: Represents a portion of a UI, reusable within an activity. Can be added, removed or replaced.

    App Component in Android Studio

    • Activities, Services, BroadcastReceivers, ContentProviders have XML declarations to be defined in the manifest file.

    UI Design

    • Layouts define the arrangement of UI elements like TextViews, Buttons. Common layouts include LinearLayout, RelativeLayout, and ConstraintLayout.
    • ConstraintLayout is often used for complex layouts managing UI elements position.

    Attributes (Layout & View)

    • Attributes define properties of UI elements. android namespace and app namespace specify attributes available in the Android SDK and in custom library attributes.
    • Examples include layout_width, text, and background.

    Size Units

    • Different units used for specifying dimensions in layouts like Density-Independent Pixels (dp), Scale-Independent Pixels (sp). Pixels (px). Percent (%).
    • Unit selection depends on the needs of the design or intended behaviour.

    View Elements

    • Each visual element on screen is a View. TextViews, Buttons, ImageViews, EditTexts are examples.

    Intents

    • Intents are messaging objects enabling communication between different components or apps.
    • Explicit Intents directly target a component.
    • Implicit Intents the system determines the appropriate component.

    Activity Life Cycle

    • Explanation of the various stages in the activity lifecycle like onCreate, onStart, onResume, onPause, onStop, onDestroy.
    • This helps you understand when your app code is run.

    Deployment

    • Testing your app on devices or emulators.
    • Examples: running the project file on a connected Android device, using Android Virtual Device.

    App Release

    • Creating a release version build, signing it with appropriate keystore.
    • Generating and uploading APK/AAB files to app stores like Google Play

    Practical Part

    • Practical application of the learnt concepts to design, build and deploy an Android app.

    Last Words

    • Separation of concerns. XML for front-end design and Java for backend functionality in the app.
