I want to make a prank to a frinend. I m coding an application that send an SMS to my phone saying something. The problem is that when my friend installs my app the device obviously alert him saying that the app has the "send SMS" permission and it may cost him money. My task is to code a second fake application that downloads silently the real app (the one that send SMS to me) and install it silently too. Without asking him to agree all that permissions. The phone of my friend is not rooted.
Is it possible to reach my task?? If yes, could you give me some advice on what I should do , or link some tutorials ?
