Provided in embodiments of the present invention are a method and device for monitoring API function scheduling in a mobile terminal. The method comprises: preconfiguring at least one to-be-monitored API function and a response event corresponding to the at least one to-be-monitored API function; configuring one monitoring processing module on the basis of the at least to-be-monitored API function; acquiring in real-time current listening data outputted by a transmission function listening module; and, when the current listening data satisfies the response event, the monitoring processing module performing a monitoring processing corresponding to the response event.
