Hi Dianne: Could you give me an advice to resolve it? Now I find the reason is /dev/xx is the root permission, but android app user is like app_xx.
To resolve this, my idea is, I create a native service run with the root right, my android app call the service api to read write the fd of /dev/xx. I don't know if my idea is ok or not. Are there any other solution. Thank you very much.
