Case Introduction
Customer Pain Points
The client required a secure, high-performance financial app for a massive user base. The core challenge was porting complex functionalities—including login authentication, permission management, and file downloads—to HarmonyOS while matching the feature parity and UX of existing Android and iOS versions. Balancing financial-grade security, seamless multi-device adaptation, and peak performance demanded deep technical expertise and precise project execution.
Solution
We adopted a forward-looking hybrid architecture (ArkTS + H5) to balance security, flexibility, and development velocity, launching the app within one month.
1.Architecture
Native Security, Web Agility
- ●Native Layer (ArkTS): Manages core security—login, registration, privacy compliance, and system permissions—leveraging HarmonyOS security APIs (e.g., screenshot blocking for sensitive pages).
- ●H5 Layer: Hosts dynamic business logic, enabling rapid updates without full app releases.
- ●Tech Stack: ArkUI declarative framework, ArkTS, H5, and TypeScript for end-to-end support from UI to data layers.
2.Security
End-to-End Protection
- ●Data: Sensitive data encrypted via MD5/SM3 algorithms within preferences and rdbStore, eliminating plaintext storage.
- ●Interaction: Native password dialogs for transactions; automatic sensitive data purge on page exit; screenshot/recording restrictions.
- ● Communication: Secure JSBridge for Native-H5 interaction over HTTPS with encrypted parameter transmission.
3.Performance
Optimized for HarmonyOS
- Multi-Device Adaptation: Responsive layouts and adaptive components ensure flawless rendering across 10+ Huawei devices (phones/tablets).
- Efficiency: H5 hotfixes eliminate frequent updates. Native components guarantee core UX. Achieved a 15% performance boost over the Android version.
Project Value
Early HarmonyOS adoption for first-mover advantage; consistent cross-platform experience; distributed multi-device convenience; stronger security and trust; smoother performance with fewer lags; hybrid native + H5 for dynamic updates and lower O&M cost—raising satisfaction and competitiveness.
