网络位置提供商不适用于ICS(华为)

我有新的华为手机Ascend G330D,机载4.0.4。 问题是“网络”位置提供程序不起作用,根本不返回任何坐标。

其他事实是 1.应用程序是正确的 - 它可以在很多Android设备上运行 2. gps位置提供商工作正常 3.即使有网络位置(即没有gps),谷歌地图应用程序也能完美运行! (我已经在/ system / app中替换了NetworkLocation.apk,之后谷歌应用程序(地图,本地)开始使用网络位置,最初他们既不工作也没有) 4.没有任何第三方应用程序(来自Market)也可以使用网络位置

由于地图不是开源的,我无法看到与使用Google API的应用程序的区别,但我猜Google地图可能只使用其他地理定位源(或授权密钥)......

有没有人想知道在哪里挖掘网络位置?

此外,我的工作代码正在使用

  • GPS提供商
  • 网络提供商

    public class MyLocationListener extends Service implements LocationListener {
    
    private static final String TAG = "MyLocationListener";

    boolean isNetworkEnabled = false;
    boolean canGetLocation = false;
    
    public double latitude = 0.0;
    public double longitude = 0.0;

    }
    
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }}
    

以这种方式使用上面的代码,只要你想要任何Activity

MyLocationListener mylistner = new MyLocationListener(context);
        double lat = mylistner.latitude;
        double lon = mylistner.longitude;
