Intermodulation method and device between third-party applications, equipment and storage medium

The invention relates to the field of computers, and provides an intermodulation method and device between third-party applications, equipment and a storage medium. The method comprises the following steps: in response to a calling operation triggered for a second application in a first application interface of a first application, switching from the first application interface to a second application interface; the method comprises the following steps: firstly, responding to a first application interface, then responding to a service processing operation triggered in the second application interface, presenting a corresponding service processing result in the second application interface, and finally responding to an ending operation triggered for the second application interface, switching from the second application interface to the first application interface, and displaying the service processing result in the first application interface. When the original third-party application cannot provide the targe
