First, the development tool download link: https://developer.harmonyos.com/cn/develop/deveco-studio
You can download development tools and SDK above! The first step at the beginning is to download the development tools (download and install), then create a new project: file->new->create project, select openharmony (required for research and development learning)
Set the project name of the current project
After clicking finish, the new project will be created successfully. Without changing anything, run it first to see if it can run. We need to create a signature file before running, otherwise it will prompt (failed to install bundle. error: no signature file.) Signing failed.
File->Project Structure
Then run the project again and it will run successfully
This is the end of my first experience (newbie starts from scratch, please give me some advice)
