Control method and system based on UI (user interface) APK (Android package)

The invention discloses a control method and system based on UI (user interface) APK (Android package). The control method includes that UI APK start commands inputted by users are received by a local-terminal device, the UI APK of the local-terminal device is started, and a UI is displayed; operations of the users on the UI are received by the local-terminal device, and corresponding operational windows are displayed; operational control commands inputted by the users at the operating windows are received by the local-terminal device; when finally set operational control commands are received, the finally set operational control commands are stored; synchronous commands inputted by the users are received by the local-terminal device, and the finally set operational control commands are transmitted to an opposite-terminal device; and the final set operational control commands are received and stored by the opposite-terminal device, and operational responses corresponding to the finally set operational control commands are performed. By the control method, the control of the opposite-terminal device by the local-terminal device is realized, and normal use of the opposite-terminal device is not affected in the process of generation of operational control commands by the local-terminal device.
