Design And Implementation Of Mobile Lottery System Based On Android

China's lottery has gone through more than 20 years,among which the welfare lottery and sports lottery have became the most important two lottery.Along with the rapid development of mobile internet industry,the application of mobile terminal is getting richer,on this basis,to develop a lottery purchasing system on mobile is surely going to be necessary and feasible.This system is mainly aimed at Android mobilephone users.In order to guarantee the security of data transmission,under the condition of analyzing advantage,disadvantage and efficiency on DES,AES,RSA...etc.and encryption algorithm,the method of combining multimode encryption with the application of DES and RSA encryption will be adopted and have the data encrpted thus to ensure its transmission security.In view of the characteristics of the Android push mechanism,after analyzing these two different push mechanism implemented by MQTT and XMPP protocol,as required by the system design,which have adopted the XMPP protocal to realize Android push mechanism.For the developed software products,which have provided a convenient channel for users to purchase welfare lottery,check lottery drawing announcement,and check prize winning amount.In the process of system function and interface testing,mainly using the method of randomly selecting users,to have function and interface testing for the system,during system feature testing mainly use the virtual script to complete test,after various tests the system tends to be steady state.
