Android - How to access Android APKs without rooting

You can use an app like App Backup & Restore. It allows you to select which apps you want to backup and it copies them to your SD card.

Try with a file browser (Astro) or something like that to browse on your tablet and then you'll find the apk's if you search good. But it is not sure they will work correctly or possible to transport them. But you can always give it a try.
