Install apk file via code forcibly

I have a scenario where I have to install an apk file through code and I dont want the user to have option either install or cancel it. For ex, I want to create an app similar to the android market. In that app, I will display list of my applications and display an install button for each app. When the user clicks the install button, the app should be installed directly without asking the user to install or not. I found a link whic开发者_如何学Ch have a method installPackage in PackageManager. I am getting compilation error when I use it. It seems that it is remove from the android framework.

Is there nay possibility to do this ?

thanks,
