PINProtectionExample is a test Android project developed for helping you implement a PIN protection layer in your application. As for now, the application is not yet available on the Google Play Store, but I will probably release a demo, and until then, you can take a look at its code hosted here.
The application shows a few test welcome fragments on the first run, and a Create PIN fragment, which you can skip, and then redirects to the Main activity. The Main activity in this case is a blank screen with only one "Settings" button which opens an Activity for changing or creating a PIN if it doesn't exist, first showing a PIN entry screen if the PIN is previously set up.
The application uses the ViewPagerIndicator library from Jake Wharton, and is licensed with the GNU GPLv3 license.
