HarmonyOS

Current Harmony delivery is a Stage-model source bundle.

The current public download for HarmonyOS is HarmonyOS Project Source. It is meant to be opened in DevEco Studio, synced with the Harmony SDK, then built into a debug or release HAP for installation.

What you need

A Huawei build machine with DevEco Studio, HarmonyOS SDK components, and device developer mode enabled.

Fastest install path

Build a debug HAP in DevEco Studio and deploy directly to a connected Harmony device.

Current truth

There is no public prebuilt HAP yet on this host. The source bundle exists so a Huawei-capable environment can finish the install path honestly.

Method 1: Build and run from DevEco Studio

Download and unzip the HarmonyOS Project Source package from the 秒搭 download center.
Open the folder in DevEco Studio.
Allow the project to sync the Harmony SDK and required components.
Connect your HarmonyOS device and enable developer mode / USB debugging.
Build the entry module and run the app directly to the device.
For first-run trust prompts, accept the normal developer-install prompts on the device.

Method 2: Generate a HAP for sideload or release flow

Open the project in DevEco Studio and confirm signing configuration.
Build the project to generate a HAP package.
If you are doing internal testing, use your debug signing flow.
If you need broader distribution, configure the Huawei signing profile required for your release target.
Install the resulting HAP with your normal HarmonyOS deployment path.

Common blockers

No DevEco Studio / SDK: the source bundle cannot be installed directly without the Huawei toolchain.
Signing profile missing: debug installs may work, but release distribution needs the proper Huawei signing setup.
Device not recognized: recheck developer mode, debugging permissions, cable trust, and Harmony SDK component sync.
