Bonjour,

Mon problème est simple je dispose d'un parseur xml qui marche sans soucis en mode console java classique. Mais dès que je tente de passez le tout sous android rien niet nada je ne comprend pas et c'est pourquoi je vous appel a l'aide.

Pour le moment je souhaite juste faire l'affichage du parsage je verrais la formation en liste plus tard mais même là sa bloque.

Voici le code :

Classe Musique [console] :

import java.net.URL;
import java.util.ArrayList;

import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;

import org.xml.sax.InputSource;
import org.xml.sax.XMLReader;


public class Test {

   public static void musique(String[] args){

       try{

           URL fichier = new URL("http://..../fichier.xml"); 

           SAXParserFactory fabrique = SAXParserFactory.newInstance();
           SAXParser parseur = fabrique.newSAXParser();
           XMLReader xr = parseur.getXMLReader(); 
           ReglageParseur gestionnaire = new ReglageParseur();
           xr.setContentHandler(gestionnaire);
           xr.parse(new InputSource(fichier.openStream()));

           ArrayList<?> rss = gestionnaire.getRss();

           for(int i = 0; i < rss.size(); i++)
               System.out.println("Élément à l'index " + i + " = " + rss.get(i));

           /*String[] x = (String[]) rss.toArray(new String[rss.size()]);
           System.out.println(x[1]);

           String st1 = (String) rss.get(0);
           String[] tokens = st1.split("#");
           System.out.println(tokens[1]);*/

       }catch(Exception e){}


       //ReglageParseur r = new ReglageParseur();




   }
}

Classe Musique [Android] :

package com.android.m;


import java.net.URL;
import java.util.ArrayList;

import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;

import org.xml.sax.InputSource;
import org.xml.sax.XMLReader;

import android.app.Activity;
import android.app.ListActivity;
import android.os.Bundle;
import android.util.Log;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;


public class Musique  extends Activity {
   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);

       TextView textview = new TextView(this); 

       try{

           URL fichier = new URL("http://.../fichier.xml"); 

           SAXParserFactory fabrique = SAXParserFactory.newInstance();
           SAXParser parseur = fabrique.newSAXParser();
           XMLReader xr = parseur.getXMLReader(); 
           ReglageParseur gestionnaire = new ReglageParseur();
           xr.setContentHandler(gestionnaire);
           xr.parse(new InputSource(fichier.openStream()));

           ArrayList rss = gestionnaire.getRss();

           for(int i = 0; i < rss.size(); i++)
               textview.setText((String) rss.get(i));


       }catch(Exception e){
           Log.e("Musique", "Exception levée" + e.getMessage());
           e.printStackTrace();
       }        

       setContentView(textview);

   }
}

Essaie de séparer chaque instructions pouvant lever une exception. En effet, faire un seul et unique bloc "try { } catch (Exception e) { }" ne permet pas vraiment de déceler le problème vu que tu rattrape tout ...

Il y a tout de même quelque chose qui me tracasse ... Tu récupère une Exception nulle .. ce qui n'est normalement pas possible. Le e.printStackTrace() devrait donner plus d'informations mais tu ne le fourni pas dans ton log.
