使用ksoap2访问android中的asmx web服务

这是我的代码，当我尝试在emulator上运行我的项目时。以下错误为“不幸的是，应用程序停止工作”。我的日志如下。请帮我解决这个错误。 我正在使用“ksoap2-android-assembly-2.4-jar-with-dependencies.jar”

这是我的xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <EditText
        android:id="@+id/txtName"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:ems="10" >

        <requestFocus />
    </EditText>

    <Button
        android:id="@+id/btnInvoke"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignRight="@+id/txtName"
        android:layout_below="@+id/txtName"
        android:text="Invoke" />

    <TextView
        android:id="@+id/lblView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignRight="@+id/btnInvoke"
        android:layout_below="@+id/btnInvoke"
        android:text="Large Text"
        android:textAppearance="?android:attr/textAppearanceLarge" />

</RelativeLayout>

检查构建路径并查看jar文件是否已在主线程上通过网络检查。临时解决方案将此添加到代码中。这不是一个好的做法，但会奏效

 StrictMode.ThreadPolicy tp = StrictMode.ThreadPolicy.LAX;
        StrictMode.setThreadPolicy(tp);

顺便说一句，您正在UI线程上进行网络，这不是一个好主意。使用

AsyncTask

或

Handler

进行网络操作。有关更多信息，请阅读
