The application automatically reads the incoming SMS and check for the specific keyword, if found it responds by replying the sender with location of the device in the form of Google Map Url.

This project was initially develop for Kitkat (Android 4) and it currently developed for latest Android OS

Methodology / Approach

The following are the algorithm of this application

• App has a default search string "smstracker" which can be changed at runtime by the user
• App runs as a daemon in background of the Android device
• Always listening for the incoming SMS
• Always capturing the GPS detail of the device at interval of 3min (amendable)
• When a SMS comes in, it reads all the content and search for the specific string e.g. "smstracker"
• If not found, the App does nothing
• If string is found, the App replies to the sender of the SMS with the URL containing the latitude, longitude on the Google Map
