Universal access method and system for LBS SDK (location based service software development kit)

The present invention discloses a universal access method and system for the LBS SDK (location based service software development kit). The method includes the following steps that: when receiving a positioning request sent by the observer, the observed activates positioning service and sends the positioning request to the positioning service; the positioning service calls an encapsulation class so as to send the positioning request to the LBS SDK and obtain positioning information fed back by the LBS SDK and sends the positioning information to the observed; and receiving the positioning information, the observed gives feedback to the observer. According to the universal access method and system for the LBS SDK (location based service software development kit) of the invention, under the observer mode, the independent encapsulation class is directly adopted to interact with the native LBS SDK; and when the LBS SDK needs to be modified, it only needs to modify the encapsulation class, and therefore, an external interface can be completely decoupled from a native SDK interface, and the unified access of the LBS SDK can be realized under a condition that codes are not required to be modified can be realized.
