Location Tracking App without Installation on other phone

We want an android app that whenever first party make a call to second party and if internet is activated on that second party mobile number then location of second party should be visible on first party mobile number. It can be done using lat long or i.p address. App should be having the similar features on truecaller also. Similarly this kind of feature is already given on facebook and some other social networking apps in their nearby locations feature. It should show location at city/ state & country level only as well as GPS location. For India, it shud show at state level for mobile numbers and at city, district, state level for landline numbers. Offline support and it shud work even without internet connection. Search & track number locations, std codes & isd codes even without internet. It shud block spam calls. If Only one party install this Aap in their mobile, should be able to see other's location even if other person did not installed the same app on their phone. Our app should take required information from other's phone if internet is activated on their phone.
