You need a bluetooth module which supports SPP(Serial Port Profile or RFcomm as called in android world).
You can easily get HC-05 bluetooth module or AUBTM-20 bluetooth module in india wich will do the work for you. But one thing you need to keep in mind is that these bare modules operate on 3.3v so u need a extra circuit to make it work with 5v microcontrollers. There are so some ready made modules built around the above ones in the market.

Bare HC-05 Module http://www.rhydolabz.com/index.php?main_page=product_info&products_id=1169
Bare AUBTM-20 module http://www.rhydolabz.com/index.php?main_page=product_info&cPath=130_132&products_id=454

5v AUBTM-20 Module http://www.rhydolabz.com/index.php?main_page=product_info&cPath=130_132&products_id=479

the HC-05 is very easy and low cost module....
and works fine in serial comm....
u can interface this module connecting the rx,tx pin to module.....
use a Bluetooth terminal software....available on Google play.....for android....to receive data on android
for a kick start refer the Bluetooth control robot.....

@sachinmm The 8051 timer can't do 1 second. It can do 50ms so count 20 times
