希望找到防止/检测Android上的GPS欺骗的最佳方法.关于如何实现这一点的任何建议,以及可以做些什么来阻止它？我猜测用户必须打开模拟位置欺骗GPS,如果这样做,那么他们可以欺骗GPS吗？

我想我只需要检测是否启用了Mock Locations？还有其他建议吗？

任何人都可以帮助显示 NMEA 句子，如 $GPRMC ..... 我正在使用以下代码：

public class SampleNMEA extends Activity implements LocationListener, GpsStatus.Listener,GpsStatus.NmeaListener{

    LocationManager lm;
    TextView output;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        output = (TextView)findViewById(R.id.out);
        lm = (LocationManager) getSystemService(LOCATION_SERVICE);

        lm.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 60000,10,this);
        final Location location=lm.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);


        output.append("\nBelow Data is about the your location:");

        output.append("\n\n\nLatit:"+location.getLatitude());
        output.append("\n\nLongitude:"+location.getLongitude());
        output.append("\n\nTime: "+location.getTime());


    }
    public void onLocationChanged(Location location) 
    {
        output.append("\n\n\nLatitude:"+location.getLatitude());
        output.append("\n\nLongitude:"+location.getLongitude());
        output.append("\n\nTime: "+location.getTime());
    }

    public void onProviderDisabled(String arg0) {
        // TODO Auto-generated method stub

    } …
