推荐答案
尝试在您的 url 中使用 https，而不是 http.
Try using https in your url, not http.
对于您的网址，请更改:
For your url, change:
String URL="http://10.0.2.2:51629/ServicioClientes.asmx";
String URL="http://10.0.2.2:51629/ServicioClientes.asmx";
到:
String URL="https://10.0.2.2:51629/ServicioClientes.asmx";
String URL="https://10.0.2.2:51629/ServicioClientes.asmx";
希望这会有所帮助，因为它对我有用.
Hope this helps, as it worked for me.
