Question

我想用设备的gps位置ping一个网址。

在onCreate中我有这个

LocationManager locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
LocationListener locationListener = new MyLocationListener();
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 5000, 10, locationListener);

和下面的MyLocationListener类

public class MyLocationListener implements LocationListener {
    private final String TAG = "Walkie.LocationListener";
    @Override
    public void onLocationChanged(Location loc) {
        String longitude = String.valueOf(loc.getLongitude());
        String latitude = String.valueOf(loc.getLatitude());
        try {
            URL url = new URL("http://url.com/gps.php?longitude=" + longitude + "&latitude=" + latitude);

            HttpURLConnection urlc = (HttpURLConnection) url.openConnection();
            urlc.setRequestProperty("User-Agent", "Android Application");
            urlc.setRequestProperty("Connection", "close");
            urlc.setConnectTimeout(1000 * 30); // mTimeout is in seconds
            urlc.connect();
        } catch (MalformedURLException e1) {
            e1.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        Log.i(TAG, "Status changed");
    }

    @Override
    public void onProviderDisabled(String provider) {
        Log.i(TAG, "Provider disabled");
    }

    @Override
    public void onProviderEnabled(String provider) {
        Log.i(TAG, "Provider enabled");
    }

    @Override
    public void onStatusChanged(String provider, int status, Bundle extras) {
        Log.i(TAG, "Status changed");
    }

}

gps.php根本没有说明，我有什么问题吗？

我在清单中有这些权限

android.permission.INTERNET对

android.permission.ACCESS_NETWORK_STATE

android.permission.ACCESS_FINE_LOCATION

Answer 1

如果长时间启动，GPS会在一段时间内冷启动可能需要几分钟。

确保您在清单

中也拥有GPS权限

<uses-permission android:name="android.permission.ACCESS_GPS"/>

同时确保它已启用且处于工作状态。

requestLocationUpdates根本不起作用
