Is it possible to install an application in the system/app directory on a un-rooted device? Right now I can do it on a rooted device, so I was wondering what I have to do to if the device is not rooted. It's a custom rom, so I can get a hold of the certificates that signed the rom.
Currently if I try on a un-rooted device, I get the permission denied (read_only file system). If anybody has an idea of how I can do this please help me. The reason why I need this done is so I can do app updates on the system applications that will be shipped with the rom and they wont be on the app store.
