Updates (OpenHarmony 3.2 Beta1 -> OpenHarmony 3.2 Beta2)
Introduced Application Sandbox
Based on the namespace mechanism, OpenHarmony introduces the application sandbox to enhance application data security and reduce the possible leakage of application data and user privacy information. It also resolves user experience and concurrency stability problems in file management caused by directory disorder and adoption of multiple file access modes.
Change Impact
After the application sandbox is enabled, the access operations of all applications incubated by the appspawn process will be restricted by the application sandbox. If an application does not adapt to the file access model of the application sandbox, it may not function in full. To access files in the /data directory, the application must use the Context API, rather than a hard-coded path. For details, see Adaptation Process.

Adaptation Guide

Change 2: The member property name in the struct of a custom component cannot be the same as the built-in property or method name.
Change Impact
