Is HarmonyOS Just a Skinned Android? A Hands‑On Demo with DevEco Studio

Huawei recently launched HarmonyOS 2.0, positioning it as a full‑scene operating system intended to reduce reliance on Android and build its own ecosystem.

Is HarmonyOS a Skinned Android?

Critics argue that HarmonyOS merely repackages Android apps, calling it a “skin”. The article clarifies that while HarmonyOS can run Android APKs through a compatibility layer, this does not make it a simple Android clone.

Hands‑On Demo: Building a HarmonyOS App

Using Huawei’s official DevEco Studio, the author creates a new project named kejihu . After writing a minimal amount of code, the app is built and run on a virtual device, demonstrating that the application launches successfully.

The generated installation package has the .hap extension, which is specific to HarmonyOS and differs from Android’s .apk. According to official documentation, future native HarmonyOS apps will use the .app format, analogous to Android’s APK.

Underlying Architecture

HarmonyOS is based on a combination of OpenHarmony and AOSP. Pure OpenHarmony lacks many Android applications, which is why the compatibility layer is essential for running existing Android apps on HarmonyOS devices.

As the ecosystem matures, more manufacturers will develop native HarmonyOS apps, and many popular apps already have HarmonyOS versions (e.g., JD, etc.).

Benefits and Features

HarmonyOS apps can use the system’s “smooth messaging” feature, display fewer ads, and support unique interactions such as swiping an icon to open a service card.

Overall, the article argues that HarmonyOS is not merely a repackaged Android system but a distinct platform aiming for cross‑device integration and a unified language for the Internet of Things.
