How to provide fake data to an android application?

Question

Android

There is an android smart with a version of android 7+. So far without root, but I can make a root if necessary.
The problem is that many applications ask for access, such as access to a location or contact list or files. The last point was the banking application, which only shows the balance, but requests a list of all possible accesses.
I'm trying to disable access through the standard manager in android, and then I go into the application - I get an error in the style of "give access, otherwise the application cannot work."
Question: can I somehow slip poppy or fake data into the application? (Storage, Location, SMS, Contacts etc). Maybe there is already some kind of software - tell me, please

Answer 2

Of the above, only the location can get wet, and even then, if the target was written by teapots.
My personal opinion is that it is better to refuse such an application. Moreover, a poorly designed banking application is a reason to think about changing banks.

Answer 3

Here. I, too, have been dreaming about application virtualization for a long time. They lived to the point that they bought a new smart xiaomi, and he Requires (!) Access to contacts to work (!) Gallery. Do you understand? Contacts for the Gallery (view photos). And without them, the gallery does not work at all. 5 years ago, I would have laughed in the face of a person who would offer such a thing.
So far, I can advise you to use alternatives and web versions of services, if available. So far, unfortunately, you have to pay for privacy with convenience.

Answer 4

Well, theoretically, you can just keep the phone under it "without anything" - without contacts, without a memory card, see geolocation disabled, but this is terribly inconvenient. Do not use such applications - because they obviously do not need it, the scheme of a beautiful calendar (plus a keylogger) as it worked 15 years ago in Windows, still works everywhere :)
