Embodiments of the present invention provide a terminal application processing method, device, and terminal, wherein the method includes: receiving a call request from a first application in a terminal to a target function module in a second application; The invocation of the target function module will not generate a call conflict, then in response to the call request, call the target function module in the second application for the first application; wherein, the invocation of the target function module will not generate a call The conflict includes: detecting that the second application does not call the target function module, and / or determining that the call to the target function module does not generate a conflict according to a preset conflict list. By adopting the present invention, function sharing can be quickly realized, and the function utilization rate of the function modules can be improved, and at the same time, the development cost of the terminal application can be greatly reduced, the development efficiency can be improved, and the calling conflict of the function modules can be accurately avoided, thereby improving the The accuracy of the call.
