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 deactivation
andSave 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
