security - is it possible to change the set of permissions for an Android app dynamically? -

is possible @ application level? or have inside os?

people might want reduce attack surface. ideally, application, @ virtually point of time, should have permission if needed, following `principle of least privilege'.

to clarify: "change", mean give permissions temporarily, , regain them sometime later when needed.

it against clarity android policys . application has or not has permisions doing . can security problem if can think of it.
