要在Android 10中进行WebService调用，可以使用以下解决方法：

1. 使用HttpURLConnection类进行WebService调用：

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;

public class WebServiceCaller {
    public static String callWebService(String url, String soapAction, String xmlInput) {
        try {
            URL requestUrl = new URL(url);
            HttpURLConnection connection = (HttpURLConnection) requestUrl.openConnection();
            connection.setRequestMethod("POST");
            connection.setRequestProperty("Content-Type", "text/xml; charset=utf-8");
            connection.setRequestProperty("SOAPAction", soapAction);
            connection.setDoOutput(true);

            OutputStream outputStream = connection.getOutputStream();
            outputStream.write(xmlInput.getBytes());
            outputStream.flush();
            outputStream.close();

            int responseCode = connection.getResponseCode();

            if (responseCode == HttpURLConnection.HTTP_OK) {
                BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
                StringBuilder response = new StringBuilder();
                String line;
                while ((line = reader.readLine()) != null) {
                    response.append(line);
                }
                reader.close();

                return response.toString();
            } else {
                return null;
            }
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }
}

使用示例：

String url = "http://example.com/myservice";
String soapAction = "http://example.com/myservice/action";
String xmlInput = "" +
        "" +
        "" +
        "" +
        "value1" +
        "value2" +
        "" +
        "" +
        "";

String response = WebServiceCaller.callWebService(url, soapAction, xmlInput);

2. 使用第三方库如Ksoap2进行WebService调用：

添加Ksoap2库的依赖：

implementation 'com.google.code.ksoap2-android:ksoap2-android:3.6.4'

使用示例：

import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.PropertyInfo;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;

public class WebServiceCaller {
    public static String callWebService(String url, String namespace, String methodName, PropertyInfo[] properties) {
        try {
            SoapObject request = new SoapObject(namespace, methodName);

            if (properties != null) {
                for (PropertyInfo property : properties) {
                    request.addProperty(property);
                }
            }

            SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
            envelope.setOutputSoapObject(request);

            HttpTransportSE transport = new HttpTransportSE(url);
            transport.call(namespace + methodName, envelope);

            SoapPrimitive response = (SoapPrimitive) envelope.getResponse();

            return response.toString();
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }
}

使用示例：

String url = "http://example.com/myservice";
String namespace = "http://example.com/webservice";
String methodName = "MyWebServiceMethod";

PropertyInfo parameter1 = new PropertyInfo();
parameter1.setName("Parameter1");
parameter1.setValue("value1");
parameter1.setType(String.class);

PropertyInfo parameter2 = new PropertyInfo();
parameter2.setName("Parameter2");
parameter2.setValue("value2");
parameter2.setType(String.class);

PropertyInfo[] properties = new PropertyInfo[]{parameter1, parameter2};

String response = WebServiceCaller.callWebService(url, namespace, methodName, properties);

这些示例均为基本示例，实际情况中可能需要根据WebService的具体要求进行参数设置和解析返回结果。
