Application updating method and device, terminal and storage medium

Abstract

The embodiment of the invention discloses an application updating method and device, a terminal and a storage medium, and belongs to the field of computers. The method comprises the steps that in therunning process of an application, a patch file to be updated of the application is obtained, the patch file comprises function names of a first type file and a second function, the first type file comprises a first function, and the second function is a function for calling the first function; when the application is started next time, inserting the patch file in front of the class file of the original version of the application in the class list of the class loader; and when a class loader is used for loading a second class of files in the class files of the original version, the execution mode of the second function is updated to interpretive execution, and the second class of files comprise the second function. When the application is updated, only the patch file needs to be inserted into the class list of the class loader, consumption of system resources and memory is reduced as much as possible on the premise that the application is successfully updated, and the service life of the terminal is prolonged.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to an application updating method, device, terminal and storage medium. Background technique [0002] ART (Android Runtime, Android operating environment), is an operating environment on the Android (Android) operating system. In the ART environment, a new optimization method - inline (inlink) is adopted, which eliminates the function call overhead by directly embedding the function (method) into the call site. In other words, inlining is merging function A into function B that calls that function A. However, when the function of the BUG (vulnerability) class is function A, if the patch file is directly loaded, when function B is called, function A in function B will still be called, and will not be called into the patch file. Therefore, the application cannot be solved. Existing BUG. [0003] At present, in order to solve the above problem, after the terminal obtains t...
