GPS精度通常指位置误差范围。不同的GPS精度通常对应着不同的误差范围。例如，在开放式空间中使用全球定位系统（GPS）时，最佳的精度可以达到几米范围内的准确性，而在城市环境中，由于建筑物等干扰因素，GPS精度可能会降低，位置误差可能达到数十米。要解决如何获取GPS精度的问题，可以使用代码示例：

import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;

public class GPSAccuracy implements LocationListener {

   private static final int MILLISECONDS_BETWEEN_LOCATION_UPDATES = 1000;
   private static final float MINIMUM_DISTANCE_CHANGE_FOR_UPDATES = 1;

   private LocationManager locationManager;
   private Location lastLocation;

   public GPSAccuracy(LocationManager manager) {
      locationManager = manager;
   }

   public boolean start() {
      boolean result = false;
      try {
         locationManager.requestLocationUpdates(
            LocationManager.GPS_PROVIDER,
            MILLISECONDS_BETWEEN_LOCATION_UPDATES,
            MINIMUM_DISTANCE_CHANGE_FOR_UPDATES,
            this);
         lastLocation = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
         result = true;
      } catch (SecurityException e) {
         e.printStackTrace();
      } catch (IllegalArgumentException e) {
         e.printStackTrace();
      }
      return result;
   }

   public void stop() {
      locationManager.removeUpdates(this);
   }

   public float getAccuracy() {
      if (lastLocation != null) {
         return lastLocation.getAccuracy();
      } else {
         return Float.NaN;
      }
   }

   @Override
   public void onLocationChanged(Location location) {
      lastLocation = location;
   }

   @Override
   public void onStatusChanged(String provider, int status, Bundle extras) {}

   @Override
   public void onProviderEnabled(String provider) {}

   @Override
   public void onProviderDisabled(String provider) {}
}
