• Edit Notes: Update and modify your existing notes as needed.
• Organize Notes: Categorize your notes using folders or tags for better organization.
• Sync across Devices: Your notes are automatically synced across all your HarmonyOS devices.

Development Setup

This section provides instructions for setting up the development environment and building the Note Taking App for HarmonyOS.

Prerequisites:

1. DevEco Studio: The official IDE for HarmonyOS development. You can download it from the Huawei Developer website.
2. Java Development Kit (JDK): Make sure you have JDK 8 or later installed on your system.
3. Android Studio (Optional): If you prefer to use Android Studio for Java development, you can set it up for HarmonyOS development by following the official guide.

Setups

1. Clone the project repository to your local machine:

git clone https://github.com/your-username/note-taking-app.git

2. Open DevEco Studio and import the project by selecting "File" > "Open" and navigating to the cloned repository folder.
3. If prompted, set up the Java development environment by configuring the JDK location.

Building the App

1. In DevEco Studio, connect your HarmonyOS device or emulator to your development machine.
2. Make sure your device or emulator is set up for development mode by following the official instructions.
3. Build the app by clicking the "Build" button in the DevEco Studio toolbar or by selecting "Build" > "Build App(s)".
4. If the build is successful, you can run the app on your connected device or emulator by clicking the "Run" button in the DevEco Studio toolbar or by selecting "Run" > "Run App".
