    You should use Local Bounded Service. See more about them here: Bounded Services.

    The idea is that Service will open and manage bluetooth connection, while Activities will bind to this service and get bluetooth socket via interface that extends IBinder. This way lifecycle of Activity will not interfere with lifecycle of bluetooth socket, plus you can share you socket with as many activities as you want.
