Learn how Java strings are objects, counted characters including spaces, and how final marks constants. Explore if else and switch decisions, plus for, while, and do-while loops with examples.

Verify Android SDK and Java JDK locations, install Intel x86 emulator accelerator, enable hardware acceleration, then run the hello world app on the Android emulator.

Understand how android apps work by viewing activities as screens with front-end design and back-end logic. Learn how the android manifest manages multiple activities and coordinates app navigation.

design the android app user interface using java code only, creating a relative layout and a button, center it, and set blue background and yellow button color.

Add multiple widgets to the app by introducing a text widget alongside the existing button, assign ids, and position with relative layout rules like above and center horizontally.

Learn to handle button click events in Java Android by adding an on click listener and callback method, updating a text view when the button is clicked.

Learn to attach both on click and on long click listeners to a single activity, handling distinct events and updating a text view accordingly.

Learn to implement android gesture handling with a gesture detector to recognize scrolling, flinging, and double taps, update a text view, and run an example.

Design and attach two fragments on a single activity to build a flexible user interface, using fragment XML layouts and a main activity, with images in the drawable folder.

Create the top section fragment Java class and the bottom section fragment layout, then inflate their views to wire the fragments in the main activity for the next lecture.

Create a workout advisor app in Android Studio using Java, building a layout with a body part spinner and a button to list workouts, with constraints and string resources.

Create a Java class to map workout types to body parts in an Android app, using string list and ArrayList with if-else logic for chest, biceps, triceps, legs, bench press.

Learn to run your Android app on an actual device by building the APJ, transferring via USB, Bluetooth, or hotspot, and installing with resources enabled.

Create an overflow menu for an Android app and wire it into the main activity, using a single-checkable group to change the background color red, blue, or green.

Learn to add animations and transitions to Android widgets by implementing simple transitions, moving a button from top to bottom, and using a transition manager to create smooth effects.

Explore how to use intents to switch between Android activities, pass data with putExtra and getString, and build a multi-activity app with main and next activity.

learn how to create and run a background android service using an intent service, register it in the manifest, and start it from an activity while observing logs.

Learn how Android threads run in parallel with the main thread, use synchronization to prevent blocking, and build a simple UI example with delayed updates.

Create a second thread using a Runnable and a new thread to offload work from the main thread, then use a Handler to update the text without crashing the app.

Create an android sqlite database by building a db helper class, defining the database name and version. Implement onCreate and onUpgrade to create products table with id and product name.

Build an Android list view by binding a string array to an array adapter, display items like fruits, and show a toast with the clicked item using onItemClick.

Learn how to add notifications to Android apps using Java, including creating a notification with icon, title, and text, and triggering it via a button and notification manager.

learn to save and retain user data with shared preferences in an Android Java app, using a username and password layout with save and display actions.

Explore the project structure for game development, detailing the Android and core folders, launcher classes, and how textures, sprite batches, and the create, render, and dispose workflows are organized.

Display an image in Android game development by creating a texture, converting it to a sprite, and rendering it with a batch from assets, while disposing to prevent memory leaks.

Explore creating texture atlases and atlas files to animate Android games, compare multiple sprites versus bone-based animation with layered parts, and optimize RAM and CPU usage by managing atlas assets.

Explore camera movement in Android games by implementing a gesture detector and gesture listener to scroll, pan, and pinch-zoom a high-resolution image, with assets setup and touch interactions.
