💻What is HarmonyOS Next? How is it Different from Android?

HarmonyOS Developers — Tue, 17 Jun 2025 07:51:32 +0000

What is HarmonyOS Next?

Introduction

The platforms that support mobile continue to change along with the mobile ecosystem. Huawei’s next-generation operating system, HarmonyOS NEXT, was formally introduced in 2023. It was developed from the ground up and is not dependent on the Android Open Source Project (AOSP). Although HarmonyOS NEXT expands upon the original HarmonyOS idea, it represents a significant strategic and technological change.
This article will cover what HarmonyOS Next is and how it is different from Android.

🌐 What is HarmonyOS NEXT?

Smartphones, wearables, tablets, smart TVs, and Internet of Things devices can all enjoy a smooth experience with Huawei’s entirely independent operating system, HarmonyOS NEXT.
HarmonyOS NEXT is not based on Android like earlier HarmonyOS versions, which still maintained some compatibility with Android apps. It brings with it a new programming language, a new app runtime, and an ecosystem that is completely exclusive to Huawei services and hardware.
🔍 Let’s see the key differences between HarmonyOS Next and Android on the table;

HarmonyOS Next — Android

Why Was HarmonyOS NEXT Created?

In response to geopolitical limitations and technological aspirations, Huawei has developed HarmonyOS NEXT. The corporation wants to create an ecosystem that is completely under its control, highly connected, and secure.
Technically, HarmonyOS NEXT makes it possible for:

Avoiding Android’s compatibility layers improved performance.
Improved privacy and security with Huawei’s in-house services and APIs
Features that are distributed, such as cross-device app flows (phone ↔ watch ↔ tablet) Through the eyes of developers; For developers, especially those with an Android background, HarmonyOS NEXT offers a fresh yet familiar experience. Its modular architecture, declarative UI style, and use of ViewModel and state management will feel intuitive. At the same time, it introduces new concepts like ArkTS (a TypeScript-based language), ArkUI (a built-in stateful UI framework), and updated models for navigation, permissions, and distributed interactions.

What About Android?

Android is a widely used platform globally, known for its flexibility, power, and large developer community. HarmonyOS NEXT represents a different approach that focuses on Huawei’s ecosystem and aims to provide a more controlled, integrated, and seamless digital experience. As a developer, embracing both platforms can expand your career opportunities, help you adapt to regional market needs, and ensure you’re prepared for a future with increasingly diverse mobile ecosystems.

App Distribution and Ecosystem

HarmonyOS NEXT apps are distributed through Huawei AppGallery, which has grown significantly in markets where Huawei devices dominate.
Huawei provides extensive development support via:
DevEco Studio (IDE similar to Android Studio)
Distributed Dev Kits
Comprehensive Documentation in English and Chinese

Conclusion

HarmonyOS NEXT is Huawei’s bold move to create a standalone, next-generation operating system with its vision for connected experiences. It presents both an opportunity and a challenge for Android developers, allowing them to use their existing skills while learning new concepts.

HMS Core Release News — HMS Core 6.6.0

HarmonyOS Developers — Fri, 12 Aug 2022 09:43:00 +0000

Released the function of saving churned users as an audience to the retention analysis function. This function enables multi-dimensional examination on churned users, thus contributing to making targeted measures for winning back such users.
Changed Audience analysis to Audience insight that has two submenus: User grouping and User profiling. User grouping allows for segmenting users into different audiences according to different dimensions, and user profiling provides audience features like profiles and attributes to facilitate in-depth user analysis.
Added the Page access in each time segment report to Page analysis. The report compares the numbers of access times and users in different time segments. Such vital information gives you access to your users' product usage preferences and thus helps you seize operations opportunities.

Debuted the auto rigging capability. Auto rigging can load a preset motion to a 3D model of a biped humanoid, by using the skeleton points on the model. In this way, the capability automatically rigs and animates such a biped humanoid model, lowering the threshold of 3D animation creation and making 3D models appear more interesting.
Added the AR-based real-time guide mode. This mode accurately locates an object, provides real-time image collection guide, and detects key frames. Offering a series of steps for modeling, the mode delivers a fresh, interactive modeling experience.

Offered the auto-smile capability in the fundamental capability SDK. This capability detects faces in the input image and then lightens up the faces with a smile (closed-mouth or open-mouth).
Supplemented the fundamental capability SDK with the object segmentation capability. This AI algorithm-dependent capability separates the selected object from a video, to facilitate operations like background removal and replacement.

Released the interactive biometric verification service. It captures faces in real time and determines whether a face is of a real person or a face attack (like a face recapture image, face recapture video, or a face mask), by checking whether the specified actions are detected on the face. This service delivers a high-level of security, making it ideal in face recognition-based payment scenarios.
Improved the on-device translation service by supporting 12 more languages, including Croatian, Macedonian, and Urdu. Note that the following languages are not yet supported by on-device language detection: Maltese, Bosnian, Icelandic, and Georgian.

Added the on-cloud REST APIs for the AI dubbing capability, which makes the capability accessible on more types of devices.
Added the asynchronous API for the audio source separation capability. On top of this, a query API was added to maintain an audio source separation task via taskId. This serves as the solution to the issue that in some scenarios, a user failed to find their previous audio source separation task when they exited and re-opened the app, because of the long time taken by an audio source separation task to complete.
Enriched on-device audio source separation with the following newly supported sound types: accompaniment, bass sound, stringed instrument sound, brass stringed instrument sound, drum sound, accompaniment with the backing vocal voice, and lead vocalist voice.

Added two activity record data types: apnea training and apnea testing in diving, and supported the free diving record data type on the cloud-side service, giving access to the records of more activity types.
Added the sampling data type of the maximum oxygen uptake to the device-side service. Each data record indicates the maximum oxygen uptake in a period. This sampling data type can be used as an indicator of aerobic capacity.
Added the open atomic sampling statistical data type of location to the cloud-side service. This type of data records the GPS location of a user at a certain time point, which is ideal for recording data of an outdoor sport like mountain hiking and running.
Opened the activity record segment statistical data type on the cloud-side service. Activity records now can be collected by time segment, to better satisfy requirements on analysis of activity records.
Added the subscription of scenario-based events and supported the subscription of total step goal events. These fresh features help users set their running/walking goals and receive push messages notifying them of their goals.

Released the HDR Vivid SDK that provides video processing features like opto-electronic transfer function (OETF), tone mapping, and HDR2SDR. This SDK helps you immerse your users with high-definition videos that get rid of overexposure and have clear details even in dark parts of video frames.
Added the capability for killing the WisePlayer process. This capability frees resources occupied by WisePlayer after the video playback ends, to prevent WisePlayer from occupying resources for too long.
Added the capability to obtain the list of video source thumbnails that cover each frame of the video source — frame by frame, time point by time point — when a user slowly drags the video progress bar, to improve video watching experience.
Added the capability to accurately play video via dragging on the progress bar. This capability can locate the time point on the progress bar, to avoid the inaccurate location issue caused by using the key frame for playback location.
