Android Developer in 7 days | Step by Step

Discover how variables act as memory spots for storing data, enabling future reference and simple operations by combining values like a and b, with clear assignment and updates.

Explore the priorities of operations and the order of operations, showing how brackets first, then multiplication, division, addition, and subtraction determine results, with left-to-right evaluation and pre/post increment notes.

Learn how increment and decrement operators work, including pre- and post-increment, their precedence over other operations, and how they affect expressions and loops.

Learn how boolean logic drives conditions in android development by using assignment operators and comparison operators, and using the logical operators and, or, and not.

Learn to implement if statements using comparison operators, else blocks, and nested conditions, using logical and, or, not, with user input via a scanner.

Demonstrate switch statements by reading a number 1–4 from the user, executing a matching case, using break, and a default if none match.

Explore how a for loop initializes, updates, and tests conditions to repeat actions, print values, and generate even numbers using modulo and increment operators.

Explore the do-while loop and compare it to for and while loops, focusing on initialization, condition, and update, while printing even numbers using modulo.

Learn how break and continue control flow in a for loop, skipping numbers divisible by four and showing that break exits the loop while continue skips an iteration.

Learn how to implement a function to avoid repetition, call it with parameters and arguments, and distinguish static versus instance methods, while reading input with a scanner and printing results.

Explain how global variables have global scope and can be accessed from anywhere, contrast with local variables that exist only within a function’s scope, and acknowledge static access.

Explore implementing a one-dimensional array of strings with a fixed size, initialize elements, zero-based indexing, looping to print all items, and reading user input to populate the array.

Master two-dimensional arrays by building and printing a 3x3 matrix using row and column indexing, memory allocation with new, and diagonal element access via nested loops.

Learn how a class is a template for objects with attributes and methods, and demonstrate creating objects and accessing their properties with the dot operator.

Create the bike class with properties and a price meter, instantiate bikes, access attributes with dot notation, and recognize object memory scope; prepare to learn constructors next.

Define public constructors to initialize class attributes during object creation, including empty and parameterized forms, and rely on automatic constructor calls when instantiating objects with specific values.

Learn inheritance in object oriented programming by extending a vehicle class to a car class, sharing attributes and methods while avoiding repetition.

Explore encapsulation in object oriented programming by making data private, using constructors, and exposing values via getters and setters to control external access.

Master the static keyword by learning how to declare class-wide variables and methods, access them via the class name, and share data across all instances without creating objects.

Explore multi-threading concepts in Android development and how to run multiple tasks in the same process. Compare synchronous and asynchronous execution to reduce wait times and improve performance.

Learn to create a thread by extending the thread class, overriding the run method, and implementing runnable to run a background loop with sleep in Android projects.

Compare runnable and thread, implement runnable in a class, override run, create and start a thread, and perform work on the main thread with sleep.

Explore array lists and linked lists, learn to add, access, remove, and update items, and see a practical employee example that demonstrates traversal and generics.

Explore linked lists as a data structure, learn when to use them for updates and deletions, and implement a generic string-based linked list with an iterator to print elements.

Dive into XML basics for Android UI, covering view groups, linear and relative layouts, and widgets like buttons and text views; learn string resources and manifest permissions.

Explore Android layout fundamentals with linear layout in vertical and horizontal orientations and master RelativeLayout for flexible positioning, including wrap_content, fill_parent, IDs, and basic UI widgets.

Learn how to build Android user interfaces using table layout to arrange views in rows and columns, including text views and buttons, with grid layout as an advanced option.

Discover how fragments split an activity into reusable user interface components, create top and bottom fragments, inflate their layouts, and include them in a single activity with proper class wiring.

Use intents to navigate Android activities via buttons. Wire on click listeners to buttons, create intents, and start a second activity from the main activity to illustrate navigation flow.

Develop an Android currency converter app that converts dollar input to pounds using a button click, parsing the input to double and displaying the converted amount in a text view.

Learn to implement a list view in Android using a string array and a simple adapter, wire it to a main activity, and display toasts on item clicks.

Create an Android broadcast system by building a sender app that dispatches broadcasts and a receiving app that uses a broadcast receiver with an intent filter to display messages.

Explore multi-threading in Android development by offloading long-running tasks to a background thread, keeping the main thread responsive with a future-based delay and synchronized blocks.

Create and manage a main thread and background work by implementing Runnable and Handler, enabling a UI text update while a separate thread runs in the background.

Learn how Android services run in the background to handle tasks like messaging notifications; the lecture demonstrates creating a simple service extending IntentService, handling intents, and logging its start.

Learn to create and trigger Android notifications using a notification builder, with ticker, title, and text, and auto-cancel. Use a pending intent to return users to the app.

Learn to design a tic tac toe layout in Android by building a 3x3 table layout of nine buttons, wiring onClick handlers, and mapping each button to a cell ID.

Learn to implement a tic tac toe game in Android by managing the active player, updating button text with X or O, handling clicks, and tracking moves.

Learn to detect a tic tac toe winner after every move by tracking each player's occupied cells and checking all rows and columns for a winning line.
