There are some usual problems on all kinds of knowledge contest:it's prone to error that determining the order of re-sponder by manual;some Responder Systems are expensive、hard to deploy and extend.It's necessary to find some systems with low cost and easy to use. In this paper, a new Responder System is designed and implemented which based on Android operation system. It can connect all kinds of wireless smart devices with the help of Wi-Fi Direct technology. Duo to the popularity of Android and Wi-Fi the system is easier to be used and deployed than other wired Responder system in addition to ensure the ac-curacy of the order of responder. The system is compatible with a variety of Android start devices. It's cost less than other Re-sponder System with dedicated hardware.
