The embodiment of the invention discloses an application control method and device. The method may comprise the steps of monitoring an incoming call for a terminal device when the terminal device operations a target application on a foreground; and operating the target application on the foreground of the terminal device in a call process after a call answering instruction for the incoming call is received when the incoming call is monitored. Through adoption of the method and the device, when a user does not want to be interrupted when using the target application, even if there is the incoming call, the usage of the target application is not influenced, and functions of the call and the target application are both taken into consideration.
