Le code que j'ai récemment mis en œuvre que génère cette erreur dans mon application Android est:

 FileOutputStream fOut = null; 
     try { 
      fOut = this.openFileOutput("employeeInformation.xml", MODE_PRIVATE); 
      try { 
       InputStream is = new URL("http://totheriver.com/learn/xml/code/employees.xml").openStream(); 
       int size = is.available(); 
       byte[] buffer = new byte[size]; 
       is.read(buffer); 
       is.close(); 
       fOut.write(buffer); 
      } catch(Exception e) { 
       e.printStackTrace(); 
      } 
     } catch (FileNotFoundException e) { 
      e.printStackTrace(); 
     } finally { 
      try { 
       fOut.close(); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } 
     } 

Est-ce que quelqu'un sait quel est le problème?

Answer 1

Ajouter la permission Internet à votre manifeste:

<uses-permission android:name="android.permission.INTERNET"/> 

Answer 2

Vous devez aller dans votre fichier Manifest dans votre projet d'application android alors section ci-dessus application à côté d'autres autorisations ajouter: android.permission.INTERNET

Votre manifeste devrait chercher quelque chose comme ceci:

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
android:versionCode="1" 
android:versionName="1.0" > 

<uses-sdk 
    android:minSdkVersion="8" 
    android:targetSdkVersion="18" /> 
.... 
<uses-permission android:name="android.permission.INTERNET" /> 
... 
<application 
android:allowBackup="true" 
.... 

garder à l'esprit la valeur (android.permission.INTERNET) est le cas sen sitif.

Espérons que cela vous fasse gagner du temps.
