Android System Library File Update via User Partition Search

The patent segments the library file storage into two distinct locations: the read-only system partition (/system/lib) for original library files and the readable-writable user partition (/data/app-lib) for upgraded library files. This segmentation allows the system to maintain stability from the read-only system partition while enabling update capability through the writable user partition, thus resolving the contradiction between system stability and update capability.

The patent introduces a library file naming mechanism as an intermediary, where upgraded library files in the user partition are assigned names that include the package name (e.g., libname-package_name.so), allowing the system to distinguish between original and upgraded library files. This intermediary naming convention enables the system to load the correct upgraded library files without compromising the read-only system partition, thus resolving the contradiction between system stability and update capability.

The patent extracts the library file update process from the entire system upgrade process. By allowing library files to be updated independently in the user partition without requiring a full system partition rewrite, the invention separates the update of library files from the update of the entire system, thus reducing system overhead while maintaining update capability.

The patent implements partial action by updating only the necessary library files in the user partition rather than performing a complete system upgrade. This partial update approach updates only the specific library files that need modification, leaving the rest of the system unchanged, thereby significantly reducing system overhead and update time while achieving the desired library file updates.
