how to instantiate an XmlPullParser in android-8?

Question

Hi--

I am trying to use an XMLPullParser to parse some XML for an android app. I am classpathing in android.jar from the android-8 SDK.

Alas, this code:

import android.util.Xml;
import org.xmlpull.v1.XmlPullParser;

class InstantiateXMLPullParser {
  public static void main( String args[] ){
    XmlPullParser xpp = Xml.newPullParser();
  }
}

fails with this error:

Exception in thread "main" java.lang.RuntimeException: Stub!
        at android.util.Xml.newPullParser(Xml.java:15)
        at InstantiateXMLPullParser.main(InstantiateXMLPullParser.java:6)

I suspect I need to specify an implementation somewhere -- it looks like once upon a time Android used org.apache.harmony.xml.ExpatPullParser as its default pull parser, but that no longer seems to be the case.

Answer 1

You seem to have more fundamental problems. java.lang.RuntimeException: Stub! will only come when you attempt to use android.jar outside of Android. Try building an Android application and running it on a device or emulator, and you will get your pull parser.

Answer 2

import java.io.InputStream;

import android.util.Xml;
import org.xmlpull.v1.XmlPullParser;

private InputStream input;

public class InstantiateXMLPullParser {
   static{
   .
   .
   .
   }
public InstantiateXMLPullParser(InputStream stream){
   this.input = stream;
   }
   .
   .
   .
}
