Abstract: A method and device for extending an APK file application. The method for extending an APK file application comprises the steps of: acquiring an initial APK file and a shell file; decompiling the initial APK file; extracting a target file which has the same file type as the shell file from the decompiled file; merging the target file with the shell file; and storing the merged file and the initial APK file into a pre-set file folder, and packaging and constructing the pre-set file folder as a target APK file. By means of the technical solution, by decompiling an initial APK file and then processing a shell file and the decompiled file, on the premise of neither changing a source code of the initial APK file nor modifying a file structure of a dex, it is flexible and convenient to add new functions to a relevant mobile application.
