SDK Android-Facebook: Không thể chia sẻ ảnh, hộp thoại không hiển thị

Question

Đây là lần đầu tiên tôi sử dụng SDK Android-Facebook. Tôi đang cố đăng một ảnh bitmap nhưng tôi tiếp tục nhận được thông báo này:

Warning: Error: com.facebook.FacebookException: Failed to copy image. 

Tôi có thể đăng liên kết đơn giản, nhưng không thể đăng liên kết đơn giản.

Tôi nên sửa lỗi này như thế nào? Ngoài ra, một điều tôi nhận thấy là StatusCallback.call() không được gọi.

public abstract class FacebookReadyBaseActivity extends Activity { 
    private static final String TAG = "FacebookReadyBaseActivity"; 

    private UiLifecycleHelper uiHelper; 

    protected PendingAction pendingAction = PendingAction.NONE;

     public void call(Session session, SessionState state, 
       Exception exception) {

     super.onCreate(savedInstanceState); 

     uiHelper = new UiLifecycleHelper(this, callback);

Cuối cùng, nó đã hoạt động!

Trong dự án HelloFacebookSample cung cấp Tôi thấy điều này trong biểu hiện:

<provider android:authorities="com.facebook.app.NativeAppCallContentProvider355198514515820" 
        android:name="com.facebook.NativeAppCallContentProvider" 
        android:exported="true"/> 

Tôi chỉ đơn giản là thay đổi một phần số sử dụng riêng ID ứng dụng Facebook của tôi. Không chắc tại sao tôi không thấy điều này trong tài liệu.
