java 创建新的 SoapObject 会炸毁 android 应用程序

Creating new SoapObject Blows up android app

提问by Pavel P

I'm new to ksoap2 and I'm trying to get example w3 schools example working. For some reason it always fails on this line.

我是 ksoap2 的新手，我正在尝试让示例 w3 学校示例工作。由于某种原因，它总是在这条线上失败。

SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);

I dont know what is causing the fail. The android app just blows up. I have set internet permisions in Manifest. Im not really sure what is going on. Thanks

我不知道是什么导致了失败。android 应用程序刚刚爆炸。我在清单中设置了互联网权限。我不太确定发生了什么。谢谢

I had the same problem. That works for me:

我有同样的问题。这对我行得通：

As the prev answer said:

正如上一个回答所说：

• In your build path clear all libraries (jar files).
• In project's main directory create a folder and named it "libs" (not "lib").
• Now Eclipse ADT Plugin will add your jar files to build path

• 在您的构建路径中清除所有库（jar 文件）。
• 在项目的主目录中创建一个文件夹并将其命名为“libs”（不是“lib”）。
• 现在 Eclipse ADT 插件会将您的 jar 文件添加到构建路径

Not realy for me. My way:

对我来说不是。我的方式：

1. In your build path remove the "ksoap2-android-assembly-2.x.x-jar-with-dependencies.jar"
2. Click OK (Ignore Errors shown)
3. In project's main directory create a folder "libs"
4. Copy the JAR-File into this directory (!)
5. In your build path add the JAR file with this directory

1. 在您的构建路径中删除“ksoap2-android-assembly-2.xx-jar-with-dependencies.jar”
2. 单击确定（忽略显示的错误）
3. 在项目的主目录中创建一个文件夹“libs”
4. 将 JAR 文件复制到此目录中 (!)
5. 在您的构建路径中，使用此目录添加 JAR 文件

For everyone having also this problem... I was trying to solve this problem for many many hours, but then I detected what my fault was: I did not correctly download the ksoap2 library, so there was only a jar file which was 21 KB, but the correct jar file is about 150KB. So make sure that you download the file correctly!

对于也有这个问题的每个人......我试图解决这个问题很多小时，但后来我发现我的错是：我没有正确下载 ksoap2 库，所以只有一个 21 KB 的 jar 文件，但正确的 jar 文件大约为 150KB。因此，请确保正确下载文件！

If you still get the same problem, try these classes (works for me):

如果您仍然遇到同样的问题，请尝试这些课程（对我有用）：

public class Main extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        String fahrenheit = CelsiusToFahrenheitWs.celsiusToFahrenheit("32");
        Toast.makeText(getApplicationContext(), fahrenheit, Toast.LENGTH_SHORT).show();
    }
}

And

和

public class CelsiusToFahrenheitWs {
    private static final String METHOD_NAME = "CelsiusToFahrenheit";
    private static final String NAMESPACE = "http://tempuri.org/";
    private static final String SOAP_ACTION = "http://tempuri.org/CelsiusToFahrenheit";
    private static final String URL = "http://www.w3schools.com/webservices/tempconvert.asmx";

    public static String celsiusToFahrenheit(String celsius) {
        String fahrenheit = null;

        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
        request.addProperty("Celsius", celsius);

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

        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
        androidHttpTransport.debug = true;

        try {
            androidHttpTransport.call(SOAP_ACTION, envelope);
            SoapPrimitive response = (SoapPrimitive) envelope.getResponse();
            fahrenheit = response.toString();
        } catch (Exception e) {
            e.printStackTrace();
            fahrenheit = null;
        }
        return fahrenheit;
    }
}

I've created an another SOAP library to call SOAP services on Android, the name of the project is AndroidSOAP ( http://wiki.javaforum.hu/display/ANDROIDSOAP/Home).

我创建了另一个 SOAP 库来在 Android 上调用 SOAP 服务，项目名称是 AndroidSOAP ( http://wiki.javaforum.hu/display/ANDROIDSOAP/Home)。

I've released a version 0.0.5 today, check it out: http://wiki.javaforum.hu/display/ANDROIDSOAP/2012/05/01/Version+0.0.5+released

我今天发布了 0.0.5 版本，请查看：http://wiki.javaforum.hu/display/ANDROIDSOAP/2012/05/01/Version+0.0.5+released

W3Schools.com is no more accepting NAMESPACE as tempuri.org which caused SOAP exception in the code. You need to use "http://www.w3schools.com/webservices/" for NAMESPACE and "http://www.w3schools.com/webservices/CelsiusToFahrenheit" for SOAP_ACTION.

W3Schools.com 不再接受 NAMESPACE 作为 tempuri.org，这会导致代码中的 SOAP 异常。你需要使用“ http://www.w3schools.com/webservices/”的命名空间和“ http://www.w3schools.com/webservices/CelsiusToFahrenheit”为SOAP_ACTION。

Hope this is help!
