SYSTEM
MOBILE APP DEVELOPMENT USING
ANDROID TECHNOLOGY

2. REASON FOR DEVLOPING
MOBILE APP CHATTING
SYSTEM
 INCREASING USE OF SMART ANDROID PHONES
 NO SERVER IS REQUIRED
 EASILY HANDLED TECHNOLOGY

11. ADVANTAGES
 Chatting has largely been a PC based
addiction. But when it comes to chatting over
cell phones the alternative are costly like
GPRS-based IM’s or SMS chat.
 Bluetooth does not require any cables and
wires.
 The processing and battery power it requires
in order to operate is very low.
 It is very easy since anyone can figure out how
to set up a connection and sync two devices
to ease.
 This technology is free for use and charges to
be paid.
