title: installing an application programmatically in the system/app/ directory
body: <p>I have an application that is located in the system/app directory, this application downloads and installs another app in the same path, I can download the app successfully, but when trying to install it I get the "access denied(read only file system)" error. My question is: is it even possible to do this or do I need to declare some permission for this or do I need to define my own permissions? The phone is rooted.</p>
