Yes.

You just want to keep track of the number of active clients to decide when
you should be running. Have two methods:
class MyConnection {
private mStartCount;
void start() {
mStartCount++;
if (mStartCount == 1) {
// Bring up connection
}
}
void stop() {
mStartCount--;
if (mStartCount == 0) {
// Bring down connection
}
}
}
And call these in each onStart() and onStop() of the activities that are
using the connection.
