In this course, you will go beyond the basics of Android Jetpack Compose, learning how to customize screens using the versatile column and row composables to arrange UI elements. Next, you will use the image composable to incorporate images seamlessly into your Compose app and implement scrolling functionality within a column or a row. Then you will explore managing state in Compose, focusing on the remember function and creating interactive UI components, such as drop-down menus and sliders. Finally, you will hoist state to enhance state access and reusability and you will integrate LiveData and ViewModel with Compose, to manage and share data effectively. At the end of this course, you will be able to develop complex and interactive user screens to display your app's content.

Lazy composables in Jetpack Compose enable efficient rendering and scrolling of large lists or grids. Navigation in Jetpack Compose provides a powerful way to navigate between different screens or destinations within an app. Together, lazy composables and navigation enhance the user experience by enabling seamless scrolling and smooth transitions between screens in Jetpack Compose apps. In this course, you will learn how to efficiently display large lists of items using the lazy column and preserve their state across screen rotations or app restarts. Next, you will explore the lazy grid, and with the help of the coil library, you will asynchronously load images in your Compose app. Then you will set up the NavController and NavHost and define the structure and connections between different screens. You will also examine advanced techniques for passing data between composables and querying data from the data layer. Finally, you will test your app on a real Android device and implement navigation using the bottom navigation bar. When you are finished with this course you will have the skills and ability to develop multiscreen applications using Jetpack Compose.

Gestures in Jetpack Compose allow developers to handle user interactions such as taps, scrolls, and drags. Additionally, animations in Jetpack Compose empower developers to bring user interface (UI) elements to life by adding dynamic transitions, effects, and visual enhancements. In this course, you will explore the preferred techniques to handle gestures using built-in gesture handling available on specific composables. By utilizing gesture modifiers, you will be able to detect and respond to tap gestures, implement smooth scrolling behavior for UI components, and create interactive and draggable elements. Additionally, you will implement swipe-to-dismiss functionality. Next, you will dive into animated visibility effects and apply slide, scale, expand, and shrink effects to UI elements. Finally, you will explore advanced animation techniques and learn how to smoothly transition between different states using animated content, create animated counters with fluid motion, and seamlessly cross-fade between different screens. When you're finished with this course you will have the toolkit for creating rich and interactive animations in Compose, with visually engaging elements.

Networking is crucial for real-world Android apps to enable seamless communication between the apps and external services, such as remote servers, databases, and application programming interfaces (APIs). Networking allows applications to store data in a persistent manner on remote servers and access this data in a well-designed and secure manner. In this course, you will learn the essential aspects of networking operations in Android applications, empowering you to interact with APIs and handle network requests effectively. We will provide an overview of the clients available for accessing REST points and guide you through best practices for accessing the Internet from your app. Next, you will set up and configure an Android Views Project. We will explore the powerful Glide library, which allows you to efficiently load and display images, even in image-heavy applications. Then, we will use real-world APIs to make GET requests using the HTTPUrlConnection client and parse JSON using the Gson library. You will master app architecture structuring, create data and user interface (UI) layers in your app, and implement robust data handling mechanisms. By incorporating coroutines, you will gain proficiency in fetching data from the backend in a more concise and structured manner. By the end of this course, you will have acquired a comprehensive skill set in Android networking, enabling you to create modern apps that interact seamlessly with APIs and deliver dynamic content from the web.

Android offers a built-in standard HttpURLConnection client for making network requests, but it can be cumbersome and involve boilerplate code for handling responses and errors. In contrast, the Retrofit library simplifies networking by providing a high-level interface, reducing boilerplate, and making application programming interface (API) interactions more concise and efficient. Additionally, using coroutines for background networking operations allows for asynchronous and non-blocking execution, preventing user interface (UI) freezes. In this course, you will learn how to set up and configure a local simple HTTP server to handle requests in your Android application. You will retrieve data from the server, display a list of restaurants, and implement functionality to view individual restaurant details. You will also handle HTTP methods like POST, PUT, and DELETE to add, edit, and remove restaurants, creating a fully functional app with server communication. Next, you will explore the powerful Retrofit library, which streamlines handling HTTP requests in your Android app. You will learn to access REST endpoints more efficiently and reduce boilerplate code, resulting in a cleaner and more maintainable codebase. Finally, you will integrate the Retrofit client with Compose, a modern Android UI toolkit, to build a seamless user interface.

Various methods can be used for persisting data locally in an Android device. App-specific files and preferences offer a lightweight and straightforward approach for storing small amounts of data, such as user settings and preferences. SQLite databases and the Room API provide a robust and efficient solution for more structured and organized data. This enables data persistence for larger datasets with powerful querying capabilities and data manipulation operations. In this course, you will learn the essential aspects of data and file storage on Android. Through hands-on practice, you will build a simple app that stores recipes locally using app-specific files. Next, you will work with storing and retrieving shared preferences, a simple yet effective method to store key-value pairs in Android. Using shared preferences, you will build features to track and utilize recently searched items and prefill forms in your app. Finally, you learn to store app details in a local SQLite database, retrieve and modify data using the SQLite API, and later connect to SQLite using the Room API.

Integrating Android apps with Firebase offers a seamless and secure solution for managing user sign-in and registration processes while enabling real-time data synchronization.
