Apps Problem in setting up connection in all activity pages.

[pradrone09]

Hi ,
Urgent request for helping me how to maintain USB Connection in all activity pages.
I have designing a app which can connect to the USB from mobile.
Lets say,
I have 5 different activity defined for different task. I am able to connect USB on page 1 of application, when I tab on page 2 it disconnected and move to page 2 , same for all the page 3.,4,.,5...
Can you please guide me how to make sure once application connected and can move to all the page (2,3,4,5) without disconnection ?
I will be disconnected only when I can exit the application.
