Java Code Examples for com.google.android.gms.location.LocationRequest#setMaxWaitTime()

/**
 * Sets up the location request. Android has two location request settings:
 * {@code ACCESS_COARSE_LOCATION} and {@code ACCESS_FINE_LOCATION}. These settings control
 * the accuracy of the current location. This sample uses ACCESS_FINE_LOCATION, as defined in
 * the AndroidManifest.xml.
 * <p/>
 * When the ACCESS_FINE_LOCATION setting is specified, combined with a fast update
 * interval (5 seconds), the Fused Location Provider API returns location updates that are
 * accurate to within a few feet.
 * <p/>
 * These settings are appropriate for mapping applications that show real-time location
 * updates.
