在ActivityManagerService中：

ActivityRecord activity = null;            if (token != null) {                int aindex = mMainStack.indexOfTokenLocked(token);                if (aindex < 0) {                    Slog.w(TAG, "Binding with unknown activity: " + token);                    return 0;                }                activity = (ActivityRecord)mMainStack.mHistory.get(aindex);<span style="white-space:pre"></span>//找到与service绑定的activity            }

添加绑定信息

 AppBindRecord b = s.retrieveAppBindingLocked(service, callerApp);            ConnectionRecord c = new ConnectionRecord(b, activity,                    connection, flags, clientLabel, clientIntent);            IBinder binder = connection.asBinder();            ArrayList<ConnectionRecord> clist = s.connections.get(binder);            if (clist == null) {                clist = new ArrayList<ConnectionRecord>();                s.connections.put(binder, clist);            }            clist.add(c);            b.connections.add(c);            if (activity != null) {                if (activity.connections == null) {                    activity.connections = new HashSet<ConnectionRecord>();                }                activity.connections.add(c);            }            b.client.connections.add(c);            clist = mServiceConnections.get(binder);            if (clist == null) {                clist = new ArrayList<ConnectionRecord>();                mServiceConnections.put(binder, clist);            }            clist.add(c);
