After the 4 Sept Samsung MH8 (JDQ37) firmware upgrade, some of my Samsung S4 users are now getting the following error message: 'An application has been forced to stop for an unauthorized attempt to access system in your device' when they try to sync our app's database with their PC database. This uses the following adb command: "C:\Program Files (x86)\MyApp\adb.exe" push "C:\Program Files
(x86)\MyApp\MyApp.db" data/data/MyApp.MyApp/files/MyApp.db". This returns 'Permission denied' now. The file has attributes world readable and world writable and syncing has always worked fine until this upgrade. The upgrade introduced Samsung Knox which is obviously preventing the file transfer to the app's data/data/MyApp.MyApp/files/ folder. Has anybody come across this issue before - and perhaps found a solution?
