What's the directory location for Newsstand documents? I saved a few magazine issues using the options available in the Google Play Newsstand app, but can't figure out where the files are stored. Nothing showed up in the /sdcard/ directories tagged with recent modification dates.

Anyone know where I should be looking? In case it's relevant, my device is ASUS MemoPad 302C.
Without root access on the device, probably nowhere. With root, most likely in /data/data/com.google.android.apps.magazines. If the app stores data on sdcard, it should be found below Android/data/com.google.android.apps.magazines.
