我一直在尝试在我的应用程序中使用 Facebook SDK，但是当Facebook.authorizeCallback使用此 Logcat 崩溃报告调用时，应用程序突然开始崩溃：

这是我的代码：

public final String[] PERMISSIONS = {};
private final String APPID = "239304262850291";
public final Facebook FACEBOOK = new Facebook(APPID);
private void loginAndAuthorize() {
FACEBOOK.authorize(CoveActivity.this,PERMISSIONS,
            new DialogListener() {

                @Override
                public void onFacebookError(FacebookError e) {
                    Log.e(TAG, "Facebook error: " + e.getMessage());
                    Toast.makeText(Activity.this,
                            "there was an error connecting to Facebook",
                            Toast.LENGTH_LONG).show();
                    dialog.dismiss();
                }

                @Override
                public void onError(DialogError e) {
                    Log.e(TAG, "General error: " + e.getMessage());
                    Toast.makeText(Activity.this,
                            "there was an error connecting to Facebook",
                            Toast.LENGTH_LONG).show();
                    dialog.dismiss();
                }

                @Override
                public void onComplete(Bundle values) {
                    isLogged = true;
                    /* DO STUFF WITH INFORMATION */

                }

                @Override
                public void onCancel() {
                    Log.d(TAG, "facebook login Cancelled");
                    Toast.makeText(Activity.this, "Login Cancelled",
                            Toast.LENGTH_LONG).show();
                    dialog.dismiss();
                }
            });
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    FACEBOOK.authorizeCallback(requestCode, resultCode, data);
    super.onActivityResult(requestCode, resultCode, data);
}

关于如何解决这个问题的任何想法？（它曾经工作到 5 分钟前......）
