Android Passing BluetoothSocket to the next Activity

Question

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?

Answer 1

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
