Arduino bluetooth button to android

Hi all,

Are there any tutorials on setting up an arduino uno with bluetooth and a button. I would like to press a button on the arduino and have an android device receive the action (via an app most likely). One the command is received I will set code to act is the button was pressed.

I find a lot of send arduino data via bluetooth but I just want to press the button and the android device receive the command.

Any help is appreciated.
Thanks a lot.

A button press generates data. I guess a pin has to go high or low when you press it, and that is surely enough to tell Arduino to send a message over serial. I imagine your real problems are at the Android end.
