Android application security

Question

Im developing a parental app which restricts outgoing calls to limited defined numbers.

I need to set a password for the app log in and is it possible to set a password which can be set to control the process of uninstall of this application.

I had gone through some of the links,but haven't reached in any conclusion.

LINK 1

LINK 2

These cannot serve my purpose... that's also not a solution.

Can anybody tell how exactly to add a watcher to serve this purpose?

Answer 1

is it possible to set a password which can be set to control the process of uninstall of this application.

You are welcome to create your own custom firmware that contains your application, and install that firmware on whatever devices you are allowed to. Your application then cannot be uninstalled.

Android SDK applications cannot "control the process of uninstall".
