SDK (software development kit) activeness analyzing method, network server and system

The invention discloses an SDK (software development kit) activeness analyzing method which includes a network server receives an application issuing request, which at least carries the source file codes of the to-be-issued application, from a client; the network server determines the SDK called by the application according to the source file codes; the network server analyzes SDK activeness according to the times, being called by the application, of the SDK. The invention further correspondingly discloses the network server and an SDK activeness analyzing system. The method has the advantages that the SDK activeness analysis is performed according to the actual use of the SDK by the issued application, the actual use conditions of the SDK can be reflected, and high accuracy of analyzing results is achieved.
