错误：图像从sd卡上传到facebook中的相册android sdk

Question

在我的Facebook Android应用程序中，我需要将图像从SD卡上传到Facebook中的特定相册。我可以创建一个相同名称的SD卡文件夹。但是在创建相册后，它会得到一个异常 - android.os.NetworkOnMainThreadException。这里是我的代码 -

private void uploadImage() 
{ 
    String ExternalStorageDirectoryPath = Environment 
       .getExternalStorageDirectory() 
       .getAbsolutePath(); 

    String targetPath = ExternalStorageDirectoryPath + "/Friends/"; 


    File targetDirector = new File(targetPath); 

    File[] files = targetDirector.listFiles(); 

    for (File file : files) 
    {  
     Bitmap bmp = BitmapFactory.decodeFile(file.getAbsolutePath()); 
     ByteArrayOutputStream stream = new ByteArrayOutputStream(); 
     bmp.compress(Bitmap.CompressFormat.PNG, 100, stream); 
     final byte[] data = stream.toByteArray(); 

     facebook.authorize(MainActivity.this, new String[]{ "user_photos,publish_checkins,publish_actions,publish_stream"},new DialogListener()   
     {     
      @Override     
      public void onComplete(Bundle values) 
      { 

       if(verify) 
       { 
        myAlbumId = createAlbumName(); 
        verify=false; 
       } 
       uploadImagesToAlbum(data, myAlbumId); 

      } 

      @Override 
      public void onFacebookError(FacebookError error) 
      { 
       Toast.makeText(MainActivity.this, "FaceBook Error", Toast.LENGTH_LONG).show(); 
      } 

      @Override      
      public void onError(DialogError e) 
      { 
       Toast.makeText(MainActivity.this, "Error", Toast.LENGTH_LONG).show(); 
      }      

      @Override      
      public void onCancel() 
      { 
       Toast.makeText(MainActivity.this, "Canceled", Toast.LENGTH_LONG).show(); 
      }   
     }); 
    } 

} 

private String createAlbumName() 
{ 
    Bundle params = new Bundle(); 
    params.putString("name", "Friends"); 
    params.putString("message", "My Test Album Description Here"); 
    mAsyncRunner.request("me/albums", params, "POST", new SampleUploadListener(), null); 
    String response = ""; 
    String albumId = ""; 
    try { 
     response = facebook.request("https://graph.facebook.com/me/albums",params,"POST"); 
    } catch (FileNotFoundException e1) { 
     // TODO Auto-generated catch block 
     e1.printStackTrace(); 
    } catch (MalformedURLException e1) { 
     // TODO Auto-generated catch block 
     e1.printStackTrace(); 
    } catch (IOException e1) { 
     // TODO Auto-generated catch block 
     e1.printStackTrace(); 
    } 
    try { 
     albumId=Util.parseJson(response).getString("id"); 
    } catch (FacebookError e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } catch (JSONException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 
    return albumId; 
} 

private void uploadImagesToAlbum(byte[] byteArray, String albumId) 
{ 
    if (albumId == null) { 
     albumId = "me"; 
    } 
    Bundle params = new Bundle(); 
    params.putByteArray("picture", byteArray); 
    mAsyncRunner.request(albumId+"/photos", params, "POST", new SampleUploadListener(), null); 


}

如何上传图片到相册？由于

Answer 1

你可以发布你的日志，使所有能够帮助你..

它的连接错误，不图片上传错误。

U无法连接直接把所有的网络访问放在一个线程或处理程序或async服务器上。

Answer 2

当应用程序尝试在其主线程上执行联网操作时，会引发此异常。 我使用新线程解决此问题

Thread thread = new Thread() 
{ 
    @Override 
    public void run() { 
     try { 
      //Your code goes here 
      }        
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
    } 
}; 

thread.start();
