A patch reuse method, applied to a system that includes a plurality of devices and a patch server, where the patch server is configured to provide patches for the plurality of devices, the plurality of devices are located in a same local area network, and the plurality of devices include at least a first electronic device and a second electronic device. The method includes: The first electronic device sends a first patch query request including reused patch matching information to the patch server, where the reused patch matching information includes first patch matching information of the first electronic device and second patch matching information of the second electronic device; and the patch server sends, based on the reused patch matching information, a reused patch package including a patch file that is required by each device to the first electronic device.

Patch reuse method and system, and electronic device

A patching method includes generating an original image through compilation for a plurality of files. If a first file in the plurality of files changes, a new index mode of the first file or new data of the first file may be appended to an end of an original image to update the first file to obtain a new image.

Patching method, related apparatus, and system

This application provides a patch package generation method and a device, which includes: when code of an application framework layer in Android operating system source code is updated, obtaining, by a server, a compilation result; determining, by the server, an Android package (APK) of a target application from the APK of the preinstalled applications by, determining, by the server, an application including code in which only one or more of a check value, a timestamp, and a register corresponding to a constant change; and differentiating, by the server, an APK of an application other than the target application in the preinstalled applications after the code of the application framework layer is updated and an APK of the application other than the target application in the preinstalled applications before the code of the application framework layer is updated, to generate a first differential package. The first differential package is relatively small, therefore reducing computation amount in the terminal and air interface consumption.
