Chargement XML depuis un site

Version imprimable

Voir 40 message(s) de cette discussion en une page

Bonjour à tous, j'essaye dans une application de charger un fichier xml depuis un site.

Voici mon code :
Code:

1 2 3 4 5 6 7 URL url = new URL("http://api.androidhive.info/music/music.xml"); DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); DocumentBuilder db = dbf.newDocumentBuilder(); InputStream in = url.openStream() ; Document doc = db.parse(new InputSource(url.openStream())); doc.getDocumentElement().normalize(); ...
Je travaille avec la version 2.2 d'android.

Mais lorsque je lance mon application je n'arrive pas à me connecter au site.

Il semble que sa soit le url.openStream() qui pose problème.

Avez-vous une solution? Merci d'avance

Bonjour,

As tu un rapport d'erreur dans ton logcat ? Pourrais tu nous le poster?

Merci

Code:

1
2
3
 
InputStream in = url.openStream() ;
Document doc = db.parse(new InputSource(url.openStream()));

devrait être

Code:

1
2
3
 
InputStream in = url.openStream() ;
Document doc = db.parse(new InputSource(in));

Tous d'abord merci de vos réponses.

Oui il est vrai que cela irait mieux avec ton bous de code nicroman.

Cela dit, rien ne change, j'ai toujours le même problème à la ligne :

Code:

InputStream in = url.openStream() ;

Non Feanorin je n'ai pas d'apport d'erreur dans mon logcat.

J'ai test le code dans un try catch de ma méthode onCreate de mon activty

Voici mon code:
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 setContentView(R.layout.main); try { URL url = new URL("http://api.androidhive.info/music/music.xml"); DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); DocumentBuilder db = dbf.newDocumentBuilder(); Toast.makeText(this, "1", Toast.LENGTH_LONG).show(); InputStream in = url.openStream() ; Toast.makeText(this, "2", Toast.LENGTH_LONG).show(); Document doc = db.parse(new InputSource(in)); Toast.makeText(this, "3", Toast.LENGTH_LONG).show(); doc.getDocumentElement().normalize(); } catch (Exception e) { System.out.println("XML Pasing Excpetion = " + e); }
Seulement la valeur 1 s'affiche à l'écran

Bonjour,

Citation:

Non Feanorin je n'ai pas d'apport d'erreur dans mon logcat.

Donc pas d'exception déjà, on peut enlever de tête l'appel dans le thread Ui et la permission, donc, est ce que tu pourrais nous dire ce que tu as dans la variable in (sa taille et est ce que les donnée présentes sont cohérentes avec ton xml, compare les deux tailles)?

Car sans information c'est compliqué de t'aider...

Ceci dit... pas sur qu'il n'y ai pas d'exception:
Avec:
Code:

1 2 System.out.println("XML Pasing Excpetion = " + e);
pas facile de détecter les exceptions....
Remplacer par:
Code:

1 2 Log.e("TAG","XML parsing errror",e);
Au moins, ca ira dans le logcat si il y a une exception.

Ensuite... vu qu'il y a un appel Internet (url.openStream()), j'imagine que le code tourne dans un thread (au moins une AsyncTask), dans ce cas, pas sur que les "Toast" fonctionne très bien... Préférer un simple:
Code:

1 2 Log.d("TAG","Been here... done that...");
A chaque fois que nécessaire.

Pour finir, on ne sait même pas quel est le problème initial...
Le document est vide ? L'InputStream est null ?

Non nicroman mon code ne tourne pas dans un thread, est-ce une erreur de ne pas la faire?

J'ai modifié le code comme tu me la dit, voici mon fichier logCat:

Non nicroman mon code ne tourne pas dans un thread, est-ce une erreur de ne pas la faire?

Oui c'est interdit de faire un appel au http depuis l'UIThread.

Edit : Je n'avais pas vu le setContentView dans le second post :aie:.

Résolu

Merci à vous Feanorin et nicroman. J'ai pu résoudre mon problème en rajoutant ces lignes de code dans ma méthode on create() :
Code:

1 2 3 4 5 if (android.os.Build.VERSION.SDK_INT > 9) { StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build(); StrictMode.setThreadPolicy(policy); }
Problème résolu ;)

Mais, comment dire si Google s'est embêté à rajouter un exception de ce type ce n'est pas pour que les développeur l'ignore ...

Si il refuse le droit de faire du réseaux à parti du ThreadUI c'est pour une raison qui est que le ThreadUI ne doit pas être bloquant. Donc au lieu de chercher à contourner le problème essaye de le comprendre.

Passe ta connexion réseaux dans un autre Thread que le Thread UI.

Le système me dit que je fais pas les choses bien... donc.... je "mute" le système... :roll:

Pas possible de faire comme cela? :/
Je ne comprends pas ce que tu veux dire par "Passe ta connexion réseaux dans un autre Thread que le Thread UI".

Est-ce ça? :

La seconde est la réponse :aie:.

En gros toute connexion réseaux ne doit pas se faire dans le Thread UI, dans ton premier exemple le runOnThreadUI est un parfait exemple de ce qui ne faut pas faire :aie:.

Non mais c'est pas grave ça... il n'y a pas de trace-file sur emulateur....
Ce n'est d'ailleurs pas une exception...

Sinon, pour ne pas s’embêter avec les Handler et les Thread... il y a les Loader et aussi les AsyncTask....

Non c'est bon le Thread me va, je peux bien me connecter et lire mon fichier xml.

Mais j'ai un autre problème, j'essaye de lire les informations de mon xml ajouté à ma list aTableRetour.

Mais lorsque j'essaye de la lire en dehors de mon thread, rien ne s'affiche parce que ma list est vide.

Voici mon code:
