After connecting to the bluetooth, I need the child to send data out through that socket. But how do I get the socket over to the childActivity?

Why do you want to switch to another activity? And why do you send data on the UI Thread?– Vladimir IvanovCommented Mar 28, 2011 at 11:20

I have 2 different design of UI that need to send out data through the socket. Therefore I need to pass the socket over.– GJianHuiCommented Mar 28, 2011 at 11:41

Or is there a way that I can call the write method in the main activity from the sub activity?– GJianHuiCommented Mar 28, 2011 at 11:58

Not sure if it is the best design, but what I did here and it worked on my simple application was to have the bluetooth connection (the socket) as a "global variable", a variable of my main application (the class which extends the Application class).
In that way all my activities can get it and set it.
For doubts on how to set/get a global variable on such way, refer to Android global variable
