Android - ユーザーが権限を取り消したときにFacebookのエラーで権限が呼び出されない

Question

ユーザーが権限を取り消した後にユーザーを再認証するという問題に困惑しています。ユーザーがアプリケーションの許可を取り消すと、Facebookに投稿するようなことをしようとするとエラーダイアログが表示されます。ただし、authorize()は呼び出されていません。それは私のコード

   public void doAuthentication() 
      { 
        // here all your FB authentication related stuff. 

       mPrefs = getPreferences(MODE_PRIVATE); 
       String access_token = mPrefs.getString("access_token", null); 
       long expires = mPrefs.getLong("access_expires", 0); 
       if(access_token != null) { 
        facebook.setAccessToken(access_token); 
       } 
       if(expires != 0) { 
        facebook.setAccessExpires(expires); 
       } 

       /* 
       * Only call authorize if the access_token has expired. 
       */ 
       if(!facebook.isSessionValid()) { 

       facebook.authorize(Cats.this, new String[] { "publish_stream", "read_stream", "publish_checkins", "offline_access"}, new DialogListener() { 
        @Override 
        public void onComplete(Bundle values) 
        { 
         SharedPreferences.Editor editor = mPrefs.edit(); 
         editor.putString("access_token", facebook.getAccessToken()); 
         editor.putLong("access_expires", facebook.getAccessExpires()); 
         editor.commit(); 
        } 

        @Override 
        public void onFacebookError(FacebookError error) {} 

        @Override 
        public void onError(DialogError e) {} 

        @Override 
        public void onCancel() {} 
       }); 
      } 

      public void onActivityResult(int requestCode, int resultCode, Intent data)  { 

    super.onActivityResult(requestCode, resultCode, data); 
    facebook.authorizeCallback(requestCode, resultCode, data); 
}

public void share(){ 
    if (! facebook.isSessionValid()) { 
     loginAndPostToWall(); 
    } 
    else { 
     postToWall(messageToPost); 
    }

     if (response == null || response.equals("") || 
       response.equals("false")) { 
      showToast("Blank response."); 
     } 
     else { 
      showToast("Message posted to your facebook wall!"); 
     } 
     finish(); 
    } catch (Exception e) {

    public void onFacebookError(FacebookError error) {

    }

private void showToast(String message){ 
    Toast.makeText(getApplicationContext(), message, Toast.LENGTH_SHORT).show(); 
} 
private void clearCredentials() { 
    AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook); 
    mAsyncRunner.logout(FacebookStatus.this, new RequestListener() { 
     @Override 
     public void onComplete(String response, Object state) { 

      runOnUiThread(new Runnable() { 

       @Override

        Log.i("facebook session2", ""+facebook.isSessionValid()); 
        showToast("You Succesfully logged out of the app"); 
        finish(); 

       } 
      }); 

     } 

     @Override 
     public void onIOException(IOException e, Object state) {} 

     @Override 
     public void onFileNotFoundException(FileNotFoundException e,

}
