Android捕獲圖像與相機並與Facebook分享sdk

我試圖用Facebook的Facebook SDK中的Facebook對話框上傳圖像（由相機捕獲）。但在Facebook登錄後它崩潰了。我找不到問題。Android捕獲圖像與相機並與Facebook分享sdk

這裏是我的代碼

protected void postStatus() { 
    byte[] data = null; 
try { 
    ContentResolver cr = getContentResolver(); 
    InputStream fis = cr.openInputStream(MyCarDealActivity.imageUri); 
    Bitmap bi = BitmapFactory.decodeStream(fis); 
    ByteArrayOutputStream baos = new ByteArrayOutputStream(); 
    bi.compress(Bitmap.CompressFormat.JPEG, 100, baos); 
    data = baos.toByteArray();    
} catch (FileNotFoundException e) { 
    e.printStackTrace(); 
} 
    Bundle parameters = new Bundle(); 
    parameters.putString("method", "photos.upload");   
    parameters.putByteArray("picture", data); 
    parameters.putString("caption", "Hello"); 
    facebook.dialog(FacebookScreen.this, "me/photos", parameters, 
      new DialogListener() { 

       @Override 
       public void onCancel() { 

       } 

       @Override 
       public void onComplete(Bundle values) { 
        Toast.makeText(FacebookScreen.this, "Published", 
          Toast.LENGTH_LONG).show(); 
        finish(); 
       } 

       @Override 
       public void onError(DialogError e) { 
        Toast.makeText(FacebookScreen.this, 
          "Error :" + e.getLocalizedMessage(), 
          Toast.LENGTH_LONG).show(); 
        finish(); 
       } 

       @Override 
       public void onFacebookError(FacebookError e) { 
        Toast.makeText(FacebookScreen.this, 
          "Error :" + e.getLocalizedMessage(), 
          Toast.LENGTH_LONG).show(); 
        finish(); 
       } 

      }); 
}

你是否檢查過你的代碼的解碼部分？ – mH16

如果你在這裏分享更多的代碼，會更容易。 – mH16

嘗試使用以下，而不是facebook.dialog：

facebook.request("me/feed", params, "POST");

這隻會創建一個AsyncTask來上傳照片，並不會顯示對話框/ \ –
