Geolocation in Android
Information
Geolocation is the ability to track a device’s whereabouts using GPS, cell phone towers,
WIFI access points or a combination of these. Since devices are used by
individuals, geolocation uses positioning systems to track an individual’s whereabouts
down to latitude and longitude coordinates, or more practically, a physical address. Both
mobile and desktop devices can use geolocation.
Geolocation refers to the use of location technologies such as GPS or IP addresses to
identify and track the whereabouts of connected electronic devices.
Because these devices are often carried on an individual's person, geolocation is often used
to track the movements and location of people and surveillance.
Geolocation is used extensively in the financial services industry to help prevent fraud and
give customers information about nearby services, but may also pose unwanted privacy
issues.

Geolocation in Android
Conclusion:
Geolocation data is something the courts have been trying to wrap their arms around for a
few years now, with no clear boundary lines yet emerging. In January 2012, the United
States Supreme Court decided in which it unanimously ruled that the attachment of a GPS
tracking device to an individual’s vehicle by police, and subsequent use of that device to
monitor the vehicle’s movements on public streets, constituted a “search or seizure” within
the meaning of the Fourth Amendment.
Contrary to many news reports at the time of the decision, however, the Jones Court
reached no conclusion on whether that search was unreasonable, or whether it required a
warrant.
