Injecting custom data into files in zip format containing apps, without unzipping, resigning or re-zipping the files

摘要

Custom data is injected into a comment field in an APK file. This creates a data driven, customized app, without unzipping, resigning or re-zipping the APK file. The APK file and the injected custom data are transmitted to a mobile computing device. The custom data can be injected into a comment field at the end of the APK file, which allows the non-customized version of the APK file and the custom data to be transmitted to the mobile computing device in succession, such that the transmission is received as a single, customized APK file. The content of the non-customized APK file and the custom data can instead be written to a new, customized APK file, which is then transmitted to the mobile computing device.
