Evaluation model of HarmonyOS code reuse and code amount:
Applet pages of top platforms in the industry: The applet pages are adapted to HarmonyOS code based on functions or features, and the pages need to be overridden. The workload is estimated based on the ratio of 1:0.7.
HarmonyOS app code: Atomic services can use only the atomic service API set. The app code needs to adapt to the code that invokes the non-atomic service API set. The workload is 30% of the code to be ported. The atomic service code can be directly reused by apps.
