Is it possible to change the system application?
Good afternoon, is there a systemic android application that uses the REQUEST_CODE_PHOTO cell, is it possible to reach its reference code and, accordingly, if possible?
That's what you're gonna need.
With the help of root, get the APK-Fail a system application, decompli it, and read its source as you wish.
I assume that you will face another problem - systems applications have permits that are available only for systems applications.
UPD Right, reading's open. So you don't need access.
