Same Bluetooth Connection for all Activities?

rich2020 · October 5th, 2011, 04:26 PM

Hi all,

New to Android, so this may seem obvious.

Here's what I have: A class called BT_Comm
BT_Comm creates a bluetooth connection and allows me to send data with it via a method called sendData(int xxx, int yyy);

Now, I use this BT_Comm in my main activity -the first one.

Say I have 10 Activities, how could I access that same BT_Comm in other Activities?

Eg:

-------------------------------------------------------
Activity 1 (main)

Code:

BT_Comm bt = new BT_Comm();

pubic void someMethod()
{
bt.sendData(xxx, yyy);
}

-------------------------------------------------------

Activity 2

Code:

private void someOtherMethod()
{
bt.sendData(xxx, yyy);
}

-------------------------------------------------------

Activity 3

Code:

private void someOtherMethod()
{
bt.sendData(xxx, yyy);
}

-------------------------------------------------------

Does anyone know how I might do this?

Thanks,

Rich.

Use a Service

Check the Sample apps for BluetoothChat, it uses a "fake" service, should help you get started at least.
