I want to build an app for my personal use. Basically the app would work like K9 web security software where it would set permissions for use of different apps and even contacts save in the phone. The app must include the following features-
> It should be a password protected app.
>The app cann't be deleted with out the password.
>Should run in android's all versions.
Coder has to hand over all Intellectual rights of the apps to me.
The cheapest proposal is encouraged.
