HarmonyOS:
HarmonyOS is an operating system developed by Huawei. It is designed to be a lightweight, modular, and versatile operating system that can run on a wide range of devices, including smartphones, tablets, smart TVs, wearables, and IoT devices. HarmonyOS aims to provide a unified user experience across different devices and enable seamless collaboration between them. It emphasizes distributed architecture, high performance, and enhanced security. HarmonyOS is open source, which allows developers to contribute to its development and build applications for the platform.
Deveco Studio:
Deveco Studio is a development environment provided by Huawei for building applications for HarmonyOS. It is an integrated development environment (IDE) that offers a comprehensive set of tools and features to streamline the process of developing HarmonyOS applications. Deveco Studio provides code editing, debugging, testing, and packaging capabilities, making it easier for developers to create applications for HarmonyOS devices. It also includes templates, examples, and documentation to assist developers in getting started with HarmonyOS app development.
ArkUI:
ArkUI is a user interface framework specifically designed for HarmonyOS. It provides a set of UI components and styles that follow the design principles of HarmonyOS, allowing developers to create visually appealing and consistent user interfaces for their HarmonyOS applications. ArkUI simplifies the process of building UI elements by providing ready-to-use components, such as buttons, lists, dialogs, and navigation elements. It also offers features like internationalization support, theme customization, and accessibility options, enabling developers to create inclusive and user-friendly applications.
Developing HarmonyOS with ArkUI:
To develop HarmonyOS applications with ArkUI, you can follow these general steps:
Step 1: Set up the development environment:
Install Deveco Studio, the IDE provided by Huawei for HarmonyOS development.
Ensure you have the necessary SDKs and tools installed for HarmonyOS development.
Step 2: Create a HarmonyOS project:
Use Deveco Studio to create a new HarmonyOS project.
Select the project template and configure the project settings.
Step 3: Add ArkUI to your project:
In your project configuration, include the ArkUI library as a dependency.
This allows you to access the UI components and styles provided by ArkUI.
Step 4: Design the user interface:
Use the ArkUI components to build the user interface of your HarmonyOS application.
Customize the UI elements according to your application’s requirements.
Step 5: Implement the application logic:
Write the necessary code to implement the functionality of your application.
This may include handling user interactions, data processing, and integration with other services or APIs.
Step 6: Test and debug:
Use the debugging and testing capabilities of Deveco Studio to ensure your application works as intended.
Fix any issues or bugs that arise during testing.
Step 7: Build and package the application:
Use Deveco Studio to build the final package of your HarmonyOS application.
Generate the necessary installation files, such as an installation package or an installation image.
Step 8: Deploy and distribute the application:
Deploy your HarmonyOS application to the target devices, such as smartphones or tablets.
Distribute the application through app stores or other distribution channels, if desired.
These are the general steps involved in developing HarmonyOS applications with ArkUI. It’s important to refer to the official documentation and resources provided by Huawei for detailed instructions, guidelines, and best practices specific to HarmonyOS development.
What We`re Doing with HarmonyOS
We Develop an application for 4 side of the App Gallery Connect(Huawei Cloud Service) usage with ArkTS (.ets) for demonstrate how to use the Huawei Cloud application could use with HarmonyOS project. Also, our application covers full-stack development
· Experience Authentication Service
· Experience Cloud Functions
· Experience Cloud Database
· Experience Cloud Storage
We Created:
You can reach our developed application with latest version of the DevEco Studio.
Here is what we created with some images:
Code Examples Part of Our Developing Process
UI Templates
We Developed templates for ArkTS UI usage. Some functions we developed, includes specific reasons like login for with cloud connections. And generally, we developed codes for make better commonly usage experience for developers.
Developing with the ArkTS:
We developed Cross Platform app for all devices where Harmony OS can work
Understanding Provider and Consumer Patterns in Ark TS
Provider
The provider pattern in Ark TS allows you to create a listenable object. Whenever this object is updated, the consumers that are subscribed to it will be notified.
Usage
class User {
username: string
}
When using the provider pattern, it is important to provide an initial value to the object.
@Provide(‘user’) currentUser: User = new User(‘joe’)
// You can update the object state for listeners
changeUser() {
this.currentUser = new User(‘hannah’)
}
Consumer
The consumer pattern in Ark TS enables components to listen for changes via a provider object.
Usage
@Consume(‘user’) currentUser: User
build() {
Column() {
Text(this.currentUser.username)
}
}
// Update also works with the consume annotation
changeUser() {
this.currentUser = new User(‘jesse’)
}
