Answer 1

is it possible , if user try to uninstall the app we get a message?

As Christopher said above, you can be notified when the user has removed your application.

PACKAGE_REMOVED broadcast is sent to notify that a package is removed. You can use it to get notified.

But I don't find it right to "prevent" user from removing your application. As a matter of UX, its their phone, and they've got full rights to add/remove whatever they want.

It is the same with PCs too!
