What is Hongmeng, OpenHarmony, HarmonyOS?

1. Hongmeng operating system

“Hongmeng Operating System” refers to the operating system of Huawei intelligent terminal. “Hongmeng Operating System” has the following characteristics:

First, a set of operating system can meet the requirements of large and small devices, achieve a unified OS, flexible deployment;
Second, the devices equipped with the operating system are integrated at the system level to form a hyperterminal, so that the hardware capability of the device can be flexibly expanded, and hardware mutual assistance and resource sharing between devices are realized.
The third is for developers, to achieve a development, multi-end deployment.

2. OpenHarmony

OpenHarmony is an open source project, by the open atoms open source foundation (https://www.openatom.org/). The Open Atom Foundation was jointly established by ten Internet companies, including Huawei, Alibaba, Tencent, Baidu, Xiaomi, Inspur, China Merchants Bank, 360, OPPO and VIVO.

The OpenHarmony Open source project consists of two main parts:

First, the basic capabilities of “Hongmeng Operating System” donated by Huawei;
The second is the contribution of other participants.

Therefore, OpenHarmony’s core contribution is still in Huawei. OpenHarmony is the base of the “Hongmeng Operating System”.

3. HarmonyOS

HarmonyOS is the “Hongmeng Operating system”, or simply “Hongmeng OS” is a commercial version based on OpenHarmony, AOSP and other open source projects.

Here are some things to note:

One is that HarmonyOS is not an open source project, but a commercial version.
HarmonyOS phones and tablets can run Android because HarmonyOS implements the existing Android ecosystem application (AOSP).

4. Hongmeng Ecology

The ecosystem includes OpenHarmony and HarmonyOS, as well as development tools and surrounding libraries. When we say “Hongmeng”, maybe we mean Hongmeng ecology.

5. When to choose OpenHarmony or HarmonyOS?

If you’re just an application developer focusing on application development for end devices, then choose HarmonyOS. If you are interested in the technology underlying HarmonyOS, want to learn about it, or want to contribute to HarmonyOS, then choose OpenHarmony. Of course, if you want to go further and do your own operating system, secondary development based on the OpenHarmony open source project is also a good choice.

Q&A

Ordering Process

1. Automatic: After making an online payment, click the (Download) link to download the source code; 2. Manual: Contact the seller or the official to check if the template is consistent. Then, place an order and make payment online. The seller ships the goods, and both parties inspect and confirm that there are no issues. TopTinker will then settle the payment for the seller. Note: Please ensure to place your order and make payment through TopTinker. If you do not place your order and make payment through TopTinker, and the seller sends fake source code or encounters any issues, TopTinker will not assist in resolving them, nor can we guarantee your funds!

Transactions and Disputes

1. Default transaction cycle for source code: The seller manually ships the goods within 1-3 days. The amount paid by the user will be held in escrow by TopTinker until 7 days after the transaction is completed and both parties confirm that there are no issues. TopTinker will then settle with the seller. In case of any disputes, TopTinker will have staff to assist in handling until the dispute is resolved or a refund is made! If the buyer places an order and makes payment not through TopTinker, any issues and disputes have nothing to do with TopTinker, and TopTinker will not be responsible for any liabilities!

Matters needing attention

1. TopTinker will permanently archive the transaction process between both parties and snapshots of the traded goods to ensure the authenticity, validity, and security of the transaction! 2. TopTinker cannot guarantee services such as "permanent package updates" and "permanent technical support" after the merchant's commitment. Buyers are advised to identify these services on their own. If necessary, they can contact TopTinker for assistance; 3. When both website demonstration and image demonstration exist in the source code, and the text descriptions of the website and images are inconsistent, the text description of the image shall prevail as the basis for dispute resolution (excluding special statements or agreements); 4. If there is no statement such as "no legal basis for refund" or similar content, any indication on the product that "once sold, no refunds will be supported" or other similar declarations shall be deemed invalid; 5. Before the buyer places an order and makes payment, the transaction details agreed upon by both parties via WhatsApp or email can also serve as the basis for dispute resolution (in case of any inconsistency between the agreement and the description of the conflict, the agreement shall prevail); 6. Since chat records and email records can serve as the basis for dispute resolution, both parties should only communicate with each other through the contact information left on the system when contacting each other, in order to prevent the other party from denying their own commitments. 7. Although the probability of disputes is low, it is essential to retain important information such as chat records, text messages, and email records, in case a dispute arises, so that TopTinker can intervene quickly.
