Due to the security issue of the information send by the
user and lack of centralized database in the present scenario,
this paper has given approach to develop a secured androidbased
location and message sharing system. In this paper we
have used Java programming language to develop the client
side, and used PHP programming language to develop
server side with MySQL as external database to store
information. In this case we are integrating the concept of
symmetric cryptography and all the information has been
encrypted before saving to the database. We have tested the
system in emulator and finally tested the system
successfully in the real life scenario using HTC android
smart phone. With the help of GPS enabled smart phone we
were able to send the longitude and latitude to the
webserver, analyzing the location data from the database
and displaying the location and trace path in the web which
helps us to know where the client is. And finally we were
able to send the message through webserver and android
device and vice-versa.
