Running the Application on a Real Device

Install HDC

1. Find the pipeline whose name is ohos-sdk-full or ohos-sdk-public, click Download Link, and select Full Package.
   Use conditional filtering: select project openharmony, branch OpenHarmony-5.1.0-Release, and a date from the previous month or a manual range.
   Then find ohos-sdk-full_5.1.0-Release, and download the full package (Windows/Linux).
   (If daily build SDK is not compatible with your DevEco Studio, try the rolling build SDK.)

2. Under the toolchain folder, locate hdc.exe and libusb_shared.ddl.
   

3. Create a folder called hdc_bin, and copy hdc.exe and libusb_shared.dll into it.

5. Open Settings on Windows → search for Edit the system environment variables.
6. In the Advanced tab, click Environment Variables....
7. Edit Path under System variables, click New, and paste your hdc_bin path.
