How to save the state of an Android CheckBox when the users exits the application?

However keep in mind this is a controlled save state. If your program should be killed due to lack of resources, you should save all appropriate info during onSaveInstanceState () and onRestoreInstanceState ()

Save the last selected instance state in perference file using SharedPreferences, then in your code always read the state from preference file when open the dialog, if no perference file existing, then use default.
