Android: Not able to get accurate latitude and longitude value

Question

In my application I want latitude and longitude value by GPS and/ or Network. My code work but some time it give accurate value some time it not give the accurate value, some time it give the value which is 10 or 20 meter far from the accurate place. Code:

mlocListener = new MyLocationListener(getApplicationContext());
    /* Use the LocationManager class to obtain GPS locations */
    LocationManager mlocManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

    if (mlocManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
        mlocManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,
                10000, 0, mlocListener);
    } else if (mlocManager
            .isProviderEnabled(LocationManager.NETWORK_PROVIDER)) {
        mlocManager.requestLocationUpdates(
                LocationManager.NETWORK_PROVIDER, 10000, 0, mlocListener);
    }

    Location gpsLocation = mlocManager
            .getLastKnownLocation(LocationManager.GPS_PROVIDER);
    Location netLocation = mlocManager
            .getLastKnownLocation(LocationManager.NETWORK_PROVIDER);

    if (gpsLocation != null) {
        mlocListener.latitude = gpsLocation.getLatitude();
        mlocListener.longitude = gpsLocation.getLongitude();

        double lat = (double) (gpsLocation.getLatitude());
        double lng = (double) (gpsLocation.getLongitude());


        Toast.makeText(this, "Location attributes using GPS Provider",
                Toast.LENGTH_LONG).show();

    } else if (netLocation != null) {
        mlocListener.latitude = netLocation.getLatitude();
        mlocListener.longitude = netLocation.getLongitude();

        double lat = (double) (netLocation.getLatitude());
        double lng = (double) (netLocation.getLongitude());



        Toast.makeText(this, "Location attributes using NETWORK Provider",
                Toast.LENGTH_SHORT).show();

    } 

Answer 1

Use loc.getAccuracy() method to check the accuracy level of location you received. If the value is less then 10(or less than that) then you can consider it , otherwise wait for location Lister to fetch another location.

getLastKnownLocation is your last known location, dont use just getAccuracy also check the time.

Better dont use getLastKnownLocation if you need only accurate location.
