I\'m using Android Studio version 0.8.2 (on Windows7). It is very annoying that when i change some file it is automatically saved. According to this i have turn off settings lik
File>Settings>Appearance & Behavior>System Settings>Synchronization> then uncheck bothSave files on frame deactivationandSave files automatically if application is idle>OK
Now, you should do this too.
File>Settings>Editor>General>Editor Tabs> then checkMark modified tabs with asterisk>OK
