Yes, there are a few sample apps you can check out. The admin and some users already shared package names that are live on Play Store, for example:
com.dechika.android
com.classo.clock
com.astrorobo.iwebnapp
com.kivelskins.kivelskinsdesigner
com.edukareonline.wbdigitech
com.msx.filehunter
Just search these package names on Google Play and you’ll find working examples made with Website to APK. They’re pretty useful if you want to see how the final output looks and functions before creating your own.
