我已经使用IIS服务器在.net中创建了Web服务，我正在尝试通过Web服务从android到.net查找数据，但是我收到此错误消息“无法序列化”
String resTxt = null;
mylistener = new gpslocation();
// Get the location manager
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
// Define the criteria how to select the location provider
criteria = new Criteria();
provider = locationManager.getBestProvider(criteria, false);
locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
Location location = locationManager.getLastKnownLocation(provider);
if (location != null) {
mylistener.onLocationChanged(location);
} else {
// leads to the settings because there is no last known location
Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(intent);
}
locationManager.requestLocationUpdates(provider, 0, 10, mylistener);

答案 0 :(得分：0)
location.getLatitude()返回什么类型？我问，因为如果您尝试发送复杂类型，则需要实现KvmSerializable并使用envelope.addMapping将该变量映射到类中。
