Where does Inbox (by Gmail) store downloaded attachments? I'm receiving email with attachments on Google Inbox. While online, I could open the attachments. Later I would be offline and would like to access those attachments.

So, anyone knows the path where those attachments were downloaded into?

(NB: I'm rooted)
You can check the following location to view the attachments:

(root)/data/data/com.google.android.apps.inbox/files/downloads

In this location you'll see a random code something like cd8ca9801230132321232sd312312ad312

Navigate to that folder and you would see few other folders named


attachments
avatars
smart_hero_mail_image
smart_mail_image


To view the attachments, navigate to "attachments" folder. Here you'll find lot of folders with random name. Sort the folders based on date, so you could file the most recent ones on top/bottom. The attachments will be stored on random folders, based on when (date) you opened the files via Inbox application.

Hope this helps.
