Our idea is that each member of the team uploads their code to SVN at a specified time (for example, 18:30) and then updates the code at a specified time (for example, 18:30), executes the ant Packaging command, Finally, the APK package will be stored in the specified directory (or upload the specified FTP directory), other departments or colleagues can access the specified address to download the latest APK

If this is not the case, it may be because I have not understood some of the principles of the system, and there should be other methods. After some exploration, I found a solution and learned more about how the Android system scans and stores the information. The next article briefly discusses the pr

Application scenarios of APK signature comparison
