The function of shelf document no longer needs if detecting that initial APK file has been provided with the function of shelf document to same initial
APK file increases same shelf document and adds if not detecting the identification information of shelf document to initial APK file
Shell processing.Specifically, the AndroidManifest.xml file for obtaining APK file first, then judges
It whether include presetting mark information corresponding with shelf document in AndroidManifest.xml file, if it is present no longer right
Initial APK file carries out shell adding, if it does not exist, then extracting to initial APK file.
By judging the legitimacy of initial APK file, effectively before extracting the initial APK file after decompiling
The file for eliminating non-APK type, avoid and extra processing carried out to the file of non-APK type；Initial APK file is added
The necessity of shell is judged, has been effectively prevented the operation for carrying out weight shell adding to initial APK file, has been improved to mobile application
The efficiency of shell adding.
