Define a class as a blueprint, create objects with constructors, set attributes, and call methods like drive, while managing a list of cars with an array list to sell.

Learn how object variables differ from class variables, use static to track total cars, and call a static method to print the total without creating an instance.

Explore public, private, protected, and default access modifiers in Java, and learn how getters and setters control a bank account's amount to enforce safe access.

Explore Java inheritance by building an animal base class and extending it with dog, bird, and fish, overriding walk and using super and this keyword in a shared animal list.

Explore the Android Studio environment and create a new Java project with an empty activity using views. Learn to use constraints, text views, and buttons with layout previews.

Create and configure an Android virtual device in Android Studio, download the Android version, and run your app on the emulator, while learning to fix initial setup and view constraints.

Learn to run the app on a real Android device by enabling developer mode and USB debugging, and trusting the PC. Then deploy from the emulator to the real device.

Create an Android Studio project, design the UI in XML, and implement a button click that shows a toast message by wiring onClick to a Java method.

Learn to get user input with edit text, convert strings to numbers, multiply them, and display the result in a text view, while validating input to prevent crashes.

Create an Android UI with custom shapes and animations, using linear and constraint layouts, a round drawable button, and tutorials on rotate, alpha, scale, and translate animations.

Create a new second activity and navigate from the main activity using intents and startActivity, passing input with putExtra and retrieving with getStringExtra.

Learn to generate an apk or Android app bundle, locate and share it, and cover uploading to Google Play via the Google Play Console with a paid developer account.

Explore how to use Android's shared preferences to persist a switch state, saving and retrieving notification settings with on checked change listeners and apply vs commit choices.

Master logcat logging to debug Android apps by using tags and log levels, such as Log.d for tracing button clicks and for loops, and filter logs for easier debugging.

Explore the Android activity lifecycle from creation to destruction, covering onCreate, onStart, onResume, onPause, onStop, and onDestroy, with sensor listeners and startup via an application class declared in the manifest.

Learn to play videos in an Android app using a VideoView, load a local raw resource, stream online video via a URL, and add internet permission in the manifest.

Create an Android options menu from a resource, inflate it in onCreateOptionsMenu, add camera and home items with icons, manage display with showAsAction and orderInCategory, and handle clicks with onOptionsItemSelected.

Explore Android themes and styles to set primary colors, action bar appearance, and icon coloring, and override eye content color and title text colors with material design guidelines.

Build an app about animals with a recycler view for scrolling, apply object oriented programming and custom fonts, and open a detail activity with a circled image and animal name.

Create a new Android Studio project and build a row item as a card view with an image and animal name, using a horizontal layout, elevation, and colors from colors.xml.

Design the main activity with a RecyclerView and implement an AnimalAdapter and AnimalRowHolder to display a list of animals by inflating item layouts and binding text and images.

Create a Java animal class with name and image, a constructor and getters and setters, then bind it to a recycler view using an animal adapter.

Learn to handle RecyclerView item clicks by defining a click interface, wiring it to the adapter, implementing on item click in the main activity, and displaying the clicked animal.

Create an animal info activity and recap the RecyclerView project, detailing card views, image and text views, intents and extras, and adapter patterns for dynamic lists.

Build a to-do list app that stores notes in the Escuela database, displays them with recycler view, and persists data when adding, editing, swiping to delete, and animating notes.

Design a polished Android UI by configuring colors, creating gradient backgrounds, and building a screen with a recycler view and card view, vector asset, and custom drawables.

Design a note holder layout using a card with title, description, and image, and implement a RecyclerView adapter and Note model to bind notes for display; prepare for database operations.

Implement a sqlite database for notes with a helper and a note handler, creating a note table and inserting entries via content values using db.insert, with versioning.

Create and use methods to read all notes, read a single note by id, update notes, and delete notes from a SQLite database using cursors and content values.

Initialize the activity, set up the recycler view with the note adapter, and load notes. Show a note input dialog, capture title and description, insert the note, and refresh list.

Detect swipes in a recycler view with an item touch helper to delete notes. Build an edit note activity with title and description fields and save and cancel actions.

Implement click-driven note editing in a to-do list app by wiring an item clicked interface, expanding text with max lines, and animating EditActivity entrance with TransitionManager.

Implement a professional Android splash screen by creating a launcher theme, a layer-list background with a centered logo, and applying it via manifest and styles to load before main content.
