Title Title Title Title The Implementation of J2EE/Android M essage P ush B ased on Observer design pattern Abstract Abstract Abstract Abstract In recent years, with the continuous development of mobile network and Android mobile phone, interaction information in people's daily lives is more and more big. Due to the power and flow rate of the mobile phone, Android intelligent mobile phone to obtain more information with less cost has become a hot research issue. Push technology is a good solution. When user have a message, P ush technology will take the initiative to sen d this message to the user, without having to rely on the user polling to inquire whether having news, make message is real-time transmitted to the Android mobile phone, and the power of Android mobile phone, flow losses low . This paper studied in detail based on the Observer design pattern, the Android client as an observer, Web server as the observed. Then the comparison of the present several technical scheme to realize push technology , choose the most simple, convenient ush to implement push technology.
Keywords Observer, Push technology , Android , ush
