8.2 Verify GPS Sensor

This simple example works for all wearables, with or without a GPS sensor. Those without GPS must pair with a

handheld to get location updates. A more complete implementation veriﬁes the presence of a GPS sensor and pairing

status before using location services, and warns users or reduces functionality when necessary. You can verify the

presence of a GPS sensor as follows:

getPackageManager().hasSystemFeature(PackageManager.FEATURE_LOCATION_GPS

8.3 Example

8.4 Golf Rangeﬁnder Example

Golf is an activity where you often want to know the distance to the next hole so you can choose the perfect club for

the shot. There are plenty of rangeﬁnders on the market today, but few are as small and convenient as a smart watch.

The golf rangeﬁnder example (Clipon Caddie) is a sample application that utilizes the GPS concepts in this section

to perform a useful task for golfers, to determine the current location and display the number of yards to the current

hole. The full source code code is available at https://github.com/GolfMarin/CliponCaddie and the installable app is

at http://cliponcaddie.com.
