    <p>I am trying to connect to a .NET WCF service in Android using kSOAP2 (v 2.1.2), but I keep getting a fatal exception whenever I try to make the service call. I'm having a bit of difficulty tracking down the error and can't seem to figure out why it's happening. The code I am using is below:</p> <pre><code>package org.example.android; import org.ksoap2.SoapEnvelope; import org.ksoap2.serialization.PropertyInfo; import org.ksoap2.serialization.SoapObject; import org.ksoap2.serialization.SoapSerializationEnvelope; import org.ksoap2.transport.HttpTransport; import android.app.Activity; import android.app.AlertDialog; import android.content.DialogInterface; import android.content.Intent; import android.os.Bundle; public class ValidateUser extends Activity { private static final String SOAP_ACTION = "http://tempuri.org/mobile/ValidateUser"; private static final String METHOD_NAME = "ValidateUser"; private static final String NAMESPACE = "http://tempuri.org/mobile/"; private static final String URL = "http://192.168.1.2:8002/WebService.Mobile.svc"; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.validate_user); Intent intent = getIntent(); Bundle extras = intent.getExtras(); if (extras == null) { this.finish(); } String username = extras.getString("username"); String password = extras.getString("password"); Boolean validUser = false; try { SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); PropertyInfo uName = new PropertyInfo(); uName.name = "userName"; PropertyInfo pWord = new PropertyInfo(); pWord.name = "passWord"; request.addProperty(uName, username); request.addProperty(pWord, password); SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); envelope.dotNet = true; envelope.setOutputSoapObject(request); HttpTransport androidHttpTransport = new HttpTransport(URL); androidHttpTransport.call(SOAP_ACTION, envelope); // error occurs here Integer userId = (Integer)envelope.getResponse(); validUser = (userId != 0); } catch (Exception ex) { } } private void exit () { this.finish(); } } </code></pre> <p>EDIT: Remove the old stack traces. In summary, the first problem was the program being unable to open a connection due to missing methods or libraries due to using vanilla kSOAP2 rather than a modified library for Android (kSOAP2-Android). The second issue was a settings issue. In the Manifest I did not add the following setting:</p> <pre><code>&lt;uses-permission android:name="android.permission.INTERNET" /&gt; </code></pre> <p>I am now having an issue with the XMLPullParser which I need to figure out.</p> <blockquote> <p>12-23 10:58:06.480: ERROR/SOCKETLOG(210): add_recv_stats recv 0</p> <p>12-23 10:58:06.710: WARN/System.err(210): org.xmlpull.v1.XmlPullParserException: unexpected type (position:END_DOCUMENT null@1:0 in java.io.InputStreamReader@433fb070) </p> <p>12-23 10:58:06.710: WARN/System.err(210): at org.kxml2.io.KXmlParser.exception(KXmlParser.java:243)</p> <p>12-23 10:58:06.720: WARN/System.err(210): at org.kxml2.io.KXmlParser.nextTag(KXmlParser.java:1363)</p> <p>12-23 10:58:06.720: WARN/System.err(210): at org.ksoap2.SoapEnvelope.parse(SoapEnvelope.java:126)</p> <p>12-23 10:58:06.720: WARN/System.err(210): at org.ksoap2.transport.Transport.parseResponse(Transport.java:63)</p> <p>12-23 10:58:06.720: WARN/System.err(210): at org.ksoap2.transport.HttpTransportSE.call(HttpTransportSE.java:100)</p> <p>12-23 10:58:06.730: WARN/System.err(210): at org.example.android.ValidateUser.onCreate(ValidateUser.java:68)</p> <p>12-23 10:58:06.730: WARN/System.err(210): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1122)</p> <p>12-23 10:58:06.730: WARN/System.err(210): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2104)</p> <p>12-23 10:58:06.730: WARN/System.err(210): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2157)</p> <p>12-23 10:58:06.730: WARN/System.err(210): at android.app.ActivityThread.access$1800(ActivityThread.java:112)</p> <p>12-23 10:58:06.730: WARN/System.err(210): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1581)</p> <p>12-23 10:58:06.730: WARN/System.err(210): at android.os.Handler.dispatchMessage(Handler.java:88)</p> <p>12-23 10:58:06.730: WARN/System.err(210): at android.os.Looper.loop(Looper.java:123)</p> <p>12-23 10:58:06.730: WARN/System.err(210): at android.app.ActivityThread.main(ActivityThread.java:3739)</p> <p>12-23 10:58:06.730: WARN/System.err(210): at java.lang.reflect.Method.invokeNative(Native Method)</p> <p>12-23 10:58:06.730: WARN/System.err(210): at java.lang.reflect.Method.invoke(Method.java:515)</p> <p>12-23 10:58:06.730: WARN/System.err(210): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:739)</p> <p>12-23 10:58:06.730: WARN/System.err(210): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:497)</p> <p>12-23 10:58:06.730: WARN/System.err(210): at dalvik.system.NativeStart.main(Native Method)</p> </blockquote>

    1. CONot sure about the first log, but in the second log the 'unknown error' is from a unhandled SOCKERR_ in the native code. There should be a logcat entry just above starting 'unknown socket error ' what is that line?

    3. COI was able to resolve the unknown socket exception. It seems I neglected (and was rather ignorant of) a setting I had to add to my Manifest file. That being: <uses-permission android:name="android.permission.INTERNET" />. Now I have an XMLPullParserException that I need to figure out.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
