There is definitely a way to activate it in 2.x without calling the
"Do you want to activate Bluetooth" dialog.  The method to toggle
Bluetooth is below (Note: this should only be used if your application
either notifies the user that Bluetooth is being enabled, or if they
select to enable Bluetooth):


private boolean ToggleBT(){
    BluetoothAdapter mBluetoothAdapter =
BluetoothAdapter.getDefaultAdapter();
    if (mBluetoothAdapter == null) {
        // Device does not support Bluetooth
    }
    else {
        if (mBluetoothAdapter.isEnabled()){
            mBluetoothAdapter.disable;
        }
        else{
            mBluetoothAdapter.enable;
        }
    }
}
