Android calls WebService to retrieve mobile phone numbers from different locations

1. The jar package used is: ksoap2-android-assembly-2.4-jar-with-dependencies.jar

2. Results

3. Code:

Note:

A. Because android4.0 and later cannot make HTTP requests in the main thread, you need to add the following code to the oncreate function of acitivity.

 if (Build.VERSION.SDK_INT >= 11) {      StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder().detectDiskReads     ().detectDiskWrites().detectNetwork().penaltyLog().build());   StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder().detectLeakedSqlLiteObjects().detectLeakedClosableObjects().penaltyLog().penaltyDeath().build());  }

B. Add the network access permission and modify the minimum version in androidmanifest.

    <uses-sdk        android:minSdkVersion="11"        android:targetSdkVersion="17" />    <uses-permission android:name="android.permission.INTERNET"></uses-permission>

The activity_main.xml code is as follows:
