I want to save an int and a boolean in my android-app. At the moment I use sharedPreferences to save the variables. What happens if I update my app or reinstall it?
Should I better use a database for saving the variables?

you can use file also to store the values. Store the file on external storage and access it later – Atish Agrawal May 23 '14 at 10:13

The SharedPreferences will get deleted. But if you use a BackupAgentHelper (more information here), you could back up your preferences to the cloud.
If you want to do it without internet access, you could save your data to the sd-card.
