How to Determine if Android Device has GPS Support

public static final String FEATURE_LOCATION_GPS was added in API level 8
Feature for getSystemAvailableFeatures() and hasSystemFeature(String).

The device has a Global Positioning System receiver and can report precise location.
Constant Value: "android.hardware.location.gps"

1. Get a PackageManager Instance and save to myPackageManager.

2. Create a Boolean Variable named bolGPSSupported. 

3. Set the Minimum and Target SDK version  to 8 or greater. 

4. In the onCreate method, add the below code. This will return the GPS ability to a boolean named bolGPSSupported. It will then display a toast displaying the GPS ability on the device to the user.

bolGPSSupported = myPackageManager.hasSystemFeature(PackageManager.FEATURE_LOCATION_GPS);

if (bolGPSSupported) {

Toast.makeText(this, "Device has GPS feature", Toast.LENGTH_LONG).show();

} else {

Toast.makeText(this, "No GPS feature!", Toast.LENGTH_LONG).show();

}

5. Compile and run!
