Fehler beim Erhalten von Facebook Profilbild in Android

Question

Ich versuche, das Facebook Profilbild mit dem Code unten zu erhalten. Ich versuche den Link, der im Protokoll ist, scheint in Ordnung, aber in der getContent() Teil bekomme ich den Fehler. Irgendwelche Ideen darüber, warum das passiert?

Mein Code ist:

imgUrl = new URL("https://graph.facebook.com/" + facebookID + "/picture?type=large"); 
              System.out.println("problem 7"); 
              System.out.println(imgUrl); 
              InputStream in = (InputStream) imgUrl.getContent(); 
              System.out.println("problem 7.5"); 
              Bitmap bitmap = BitmapFactory.decodeStream(in); 
              System.out.println("problem 8"); 

Der Fehler ist wie folgt:

Edit:

ich meinen Code wie unten aktualisiert, und jetzt immer Fehler wie folgt:

Thread thread = new Thread() { 
              public void run() { 
               Message message = new Message(); 
               try { 
                imgUrl = new URL("https://graph.facebook.com/" + facebookID + "/picture?type=large"); 
                System.out.println("problem 7"); 
                System.out.println(imgUrl); 
                Bitmap bitmap = BitmapFactory.decodeStream(imgUrl.openConnection().getInputStream()); 
                System.out.println("problem 8"); 
                ByteArrayOutputStream stream = new ByteArrayOutputStream(); 
                bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream); 
                byteArray1 = stream.toByteArray(); 
                image1 = new ParseFile("profilePhoto.jpg", byteArray1, "image/jpg"); 
                image2 = new ParseFile("profilePhoto2.jpg", byteArray1, "image/jpg"); 
               } catch (Exception e) { 
                Log.e("MYAPP", "unexpected JSON exception", e); 
               } 


              } 
             }; 
             thread.start();

Answer 1

Sie können Thread oder AsyncTask verwenden, um Ihr Bild im Hintergrundthread herunterzuladen. Hier ist ein Beispiel dafür, wie man es mit thread macht.

Thread thread = new Thread() { 
     public void run() { 

     try{ 
     imgUrl = new URL("https://graph.facebook.com/" + facebookID + "/picture?type=large"); 
              System.out.println("problem 7"); 
              System.out.println(imgUrl); 
              InputStream in = (InputStream) imgUrl.getContent(); 
              System.out.println("problem 7.5"); 
              Bitmap bitmap = BitmapFactory.decodeStream(in); 
              System.out.println("problem 8"); 
     } catch (Exception e) { 

     } 


     } 
    }; 
    thread.start(); 
    }
