It would be possible to clear SharedPreferences every time, either when the main activity is destroyed or when the app is next run. However, as @CommonsWare points out, doing this would miss the whole point of SharedPreferences. (And check out @CommonsWare's reputation to see whether or not to believe them.) The purpose of SharedPreferences is to store values to use the next time the app is run. If you clear them automatically every time...

You can just use a variable to store your data. This variable will naturally be cleared every time the app closes.

Better to go with other options instead of Shared Preferences.

Using Application class to store the data is one of the options, through which you can achieve your requirement.
