Android Question Sharing one big file between two apps, without using external storage

[JGiunta]

Hello,
I am a new developer, and i'm trying to share a big .zip file between two of my apps, without letting the user know.
Now, the problem lies here:
-Since some of the phones where these apps won't have an external storage (SD cards), i can't use GetSafeDirDefaultExternal.
-Since the file is quite big (about 100 MB), i can't pass it using intents. (I have read the limit is 1 MB per intent, and have tried this (DonManfred's last answer) and confirmed it doesn't work)
-Since the user shouldn't know that i'm passing the files, i can't use any prompts or anything that lets him choose the file.

Thank you for your time!

You can use a custom action, it will start an activity in your app, which you will then immediately close.
