Hi, 1) Geo location Integration :- to achieve this we have run a background service in android which will run infinitely (until you uninstall the device). This service will send the coordinates of the mobile in every 40 seconds (or any desired time). The coordinates will be in the form of longitude and latitude. 2) login system by login system it means that it has sign in, sign up, 3)Automated SMS Sending It should be known on which conditions the SMS are automated. whether they are time dependent or should be fired based on the other events. 4)Syncing Offline Data If i am correct then By Syncing Offline Data means to get all the contacts in the phone book (Contacts of mobile (sim contacts + phone contacts)) it can be done offline. and also after accessing data they can be sent to you.
