我尝试使用twitter4j连接到Twitter.但它显示标题所说的错误.

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_login);

    twitterConsumerKey = getIntent().getStringExtra(TWITTER_CONSUMER_KEY);
    twitterConsumerSecret = getIntent().getStringExtra(TWITTER_CONSUMER_SECRET);
    if(twitterConsumerKey == null || twitterConsumerSecret == null){
        Log.e(Constants.TAG, "ERROR: Consumer Key and Consumer Secret required!");
        Login.this.setResult(TWITTER_LOGIN_RESULT_CODE_FAILURE);
        Login.this.finish();
    }

    mProgressDialog = new ProgressDialog(this);
    mProgressDialog.setMessage("Please wait...");
    mProgressDialog.setCancelable(false);
    mProgressDialog.setCanceledOnTouchOutside(false);
    mProgressDialog.show();

    twitterLoginWebView = (WebView)findViewById(R.id.twitter_login_web_view);
    twitterLoginWebView.setWebViewClient( new WebViewClient()
    {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url)
        {
            if( url.contains(Constants.TWITTER_CALLBACK_URL))
            {
                Uri uri = Uri.parse(url);
                Login.this.saveAccessTokenAndFinish(uri);
                return true;
            }
            return false;
        }

        @Override
        public void onPageFinished(WebView view, String url) {
            // TODO …
