What is an ab file and how do I open an ab file?
The Android SDK (Software Development Kit) program creates and accesses files appended with the .ab extension. This software has a version for Microsoft Windows-based systems, and users can install another version for their Mac-based platforms. The Android Debug Bridge application is an applet integrated into the Android SDK software, and this is a command-line program. The content of files in the AB format consists of references to developer libraries and other files used by Android development project output files. These AB files are backup files used to restore data associated to an Android application development project created using the Android SDK software. Google developed the Android SDK software and the AB file format. Usually, AB files are not comprised of APK files, which are the Android mobile applications themselves, but rather just snapshots and references to other files and elements. "adb backup -all" is a command users can type to create an AB backup file of an Android SDK project and store it in the directory where the project is found. "adb backup -apk -all" on the other hand creates an AB backup file with the associated APK file in the directory where the Android SDK project is found. The "adb restore backup.ab" command will restore the application.
