What is Android Jetpack and why should we use it?

What is Android Jetpack?

The Android Jetpack is a compilation of Android software elements that assist in the creation of exceptional Android applications.

These software elements facilitate the following:

1. Adherence to best practices and reduction of boilerplate code.
2. Simplification of complex tasks.

Previously, there were various difficulties, including:

1. Handling activity lifecycles.
2. Maintaining stability during configuration changes.
3. Preventing memory leaks.

Fortunately, the software components of Android Jetpack have successfully addressed these significant challenges.

The answer to all problems lies in Andriod Jetpack, which is also known for its frequent updates, ensuring we have the latest version available.

Jetpack consists of the androidx.* package libraries, which are separated from the platform APIs. As a result, it provides backward compatibility, allowing compatibility with previous versions.

Android Jetpack Components

The Android Jetpack components consist of a set of libraries designed to work harmoniously together while leveraging the productivity-enhancing features of the Kotlin language.

These software elements are categorized into four groups:

1. Foundation Components
2. Architecture Components
3. Behavior Components
4. UI Components

Now, let's explore each category in detail.

Foundation Components

The foundation components offer the following features:

• Compatibility with previous versions
• Testing capabilities
• Support for the Kotlin programming language.

Here is a complete list of all the foundation components:

1. App Compat: Ensure smooth functioning on older Android versions by incorporating support for implementing the material design user interface.
2. Android KTX: A collection of Kotlin extensions that allow writing more concise and idiomatic Kotlin code.
3. Multidex: Enables apps to support multiple dex files, accommodating their needs.
4. Test: An Android testing framework designed for conducting unit and runtime UI tests.

Architecture Components

The architecture components contribute to the development of:

• Apps that are resilient and reliable
• Apps that can be easily tested
• Apps that are easily maintainable

The following are the architecture components:

Data Binding: Utilize a declarative approach to connect user interface elements in our layout with data sources within our app.

Lifecycles: Effectively handle the lifecycles of activities and fragments in our app.

LiveData: Enable views to receive notifications about any changes that occur in the database.

Navigation: Take care of all the necessary tasks related to in-app navigation.

Paging: Load information gradually on demand from the data source.

Room: Enable smooth and efficient access to a SQLite database.

ViewModel: Effectively manage data related to the user interface, considering the lifecycle of the app.

WorkManager: Manage various background jobs in Android according to our chosen circumstances.

Behavior Components

The behavior components facilitate the seamless integration of various standard Android services, including:

1. Notifications
2. Permissions
3. Sharing
4. Assistant

Below are the complete list of behavior components:

1. Download Manager: Efficiently manage and schedule large downloads in the background, with built-in support for automatic retries.
2. Media & Playback: Incorporate backward-compatible APIs for media playback and routing, including compatibility with Google Cast.
3. Notifications: Offer a notification API that ensures backward compatibility, enabling seamless integration with wearable devices and automobile systems.
4. Permissions: Utilize compatibility APIs to check and request permissions within your app, ensuring compatibility across different Android versions.
5. Preferences: Design interactive settings screens that allow users to customize their app experience.
6. Sharing: Implement a share action that seamlessly integrates with your app's action bar.
7. Slices: Create versatile UI components that can present app data outside the app itself, extending compatibility all the way back to Android 4.4.

UI Components

The UI components offer various widgets and aids that enhance the usability of your application, making it both effortless and enjoyable to navigate.

Here is a list of all the UI components available:

The Android Jetpack provides assistance in various areas:

• Animation and Transitions: Widgets can be moved and screen transitions can be smoothly executed.
• Auto: Includes components for developing Android Auto apps.
• Emoji: Allows the use of updated emoji fonts on older platforms.
• Fragment: Serves as a fundamental building block for creating composable UIs.
• Layout: Offers various algorithms for arranging widgets on the screen.
• Palette: Extracts useful information from color palettes.
• TV: Provides components for developing Android TV apps.
• Wear: Offers components for developing apps for wearable devices.

Utilizing Android Jetpack is beneficial in these ways. It is recommended to start incorporating it into our development process.
