Impossible d'écrire sur la carte SD sur mon appareil Android

Question

Je suis en train de télécharger des images à partir du serveur et de l'enregistrer sur la carte SD, mais il a échoué

Quand je l'essayer sur l'émulateur ou un autre appareils fonctionne correctement mais mon appareil non. Mon appareil est un mini-galaxie gt S5570

Voici mon code:

public String downloadImage(String imageUrl, String id, String folder) { 
     String path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/FBLogoQuiz/" + folder + "/"; 
     Log.d("path", path); 
     File FBLogoQuiz = new File(path); 
     FBLogoQuiz.mkdirs(); 
     FBLogoQuiz.mkdir(); 
     String data = ""; 
     try { 
      URL url = new URL(imageUrl); 
      HttpURLConnection connection = (HttpURLConnection) url.openConnection(); 
      connection.setDoInput(true); 
      connection.connect(); 
      InputStream input = connection.getInputStream(); 
      Bitmap myBitmap = BitmapFactory.decodeStream(input); 

      // create a File object for the parent directory 
      File FBLogoQuizDirectory = new File(path, id + ".png"); 

      // have the object build the directory structure, if needed. 
      FBLogoQuizDirectory.createNewFile(); 
      data = String.valueOf(String.format(path + id + ".png")); 

      FileOutputStream stream = new FileOutputStream(data); 

      ByteArrayOutputStream outstream = new ByteArrayOutputStream(); 
      myBitmap.compress(Bitmap.CompressFormat.PNG, 85, outstream); 
      byte[] byteArray = outstream.toByteArray(); 

      stream.write(byteArray); 
      stream.close(); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 

     return data; 

    } 

Manifest.xml

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

Answer 1

createNewFile() ne crée pas un nouveau répertoire quand il crée le fichier. Vous devez faire:

FBLogoQuizDirectory().getParentFile().mkdirs(); 

Avant de créer le fichier.
