changing OWNERSHIP of a file copied to device

When I copy a file from assets to the device, it copies just fine. The only problem is ownership. The file is ending up with the owner being 'app_59', and I need it to be 'system'. Wh开发者_开发技巧en I adb push a file, it goes as 'system'. I tried chown, I tried chmod 0777 the file, I just cannot seem to do it! Can anyone help :(

An application can't write something as the system user. That would be a serious violation of security. Also production devices do not provide root access from the shell, so it is not possible to push something to the device as anything besides the shell user; I assume you are doing your push on to the emulator, which is a very different environment in this regard (shell can run as root), so not applicable to a real device.
