Application Development Overview
NOTE
You are reading documents of OpenHarmony 3.2 Release. Obtain the compatible SDK during your application development.
The application development documents provide reference for you to develop applications using the APIs provided by OpenHarmony. They walk you through how to use JavaScript APIs to develop applications on the standard system.
The documents are carefully organized as follows:
Getting Started
Here you'll learn how to quickly get started with OpenHarmony application development.
Browse the documents on the instructions for quickly building your first application and the basics about OpenHarmony applications.
Check out the development fundamentals, which comprise descriptions of the package structure configuration file for OpenHarmony applications and the instructions for use of resource files.
Development
To facilitate your application development, we provide development guidelines for key features.
First thing first, familiarize yourself with the two cornerstone frameworks in OpenHarmony applications:
- Application framework: Application Models
- UI framework: UI Development
All applications should be developed on top of these frameworks.
Then, equip yourself for developing the key features, with the following guidelines:
- Web
- Notification
- Window Manager
- WebGL
- Media
- Security
- Connectivity
- Telephony Service
- Data Management
- File Management
- Task Management
- Device
- Device Usage Statistics
- DFX
- Internationalization
