Example 66 with LocationManager

use of android.location.LocationManager in project Parse-SDK-Android by ParsePlatform.

the class LocationNotifier method getCurrentLocationAsync.

/**
 * Asynchronously gets the current location of the device.
 *
 * <p>This will request location updates from the best provider that match the given criteria
 * and return the first location received.
 *
 * <p>You can customize the criteria to meet your specific needs. * For higher accuracy, you can
 * set {@link Criteria#setAccuracy(int)}, however result in longer times for a fix. * For better
 * battery efficiency and faster location fixes, you can set {@link
 * Criteria#setPowerRequirement(int)}, however, this will result in lower accuracy.
 *
 * @param context The context used to request location updates.
 * @param timeout The number of milliseconds to allow before timing out.
 * @param criteria The application criteria for selecting a location provider.
 * @see android.location.LocationManager#getBestProvider(android.location.Criteria, boolean)
 * @see android.location.LocationManager#requestLocationUpdates(String, long, float,
 *     android.location.LocationListener)
