android - 如何解决无法解决 "api.twitter.com"没有地址与主机名关联

Question

当我尝试在 Twitter 上分享帖子时出现此错误我将 twitter4j 用于库的 Twitter 类是:

public class TwitterActivity extends Activity {

    private Twitter twitter;

    private RequestToken requestToken = null;
    public static final String PREFS = "MyPrefsFile";
    final public static String CALLBACK_URL = "app://casa";
    private SharedPreferences shared;
    private RequestToken re;
    private int it = 0;
    private String frase = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_twitter);

        it = getIntent().getExtras().getInt("punteggio");
        frase = getIntent().getExtras().getString("frase");
        shared = this.getSharedPreferences(PREFS, Context.MODE_PRIVATE);

        new updateTwitterStatus().execute();

    }

    @Override
    public void onNewIntent(Intent data) {
        super.onNewIntent(data);
        dealWithTwitterResponse(data);

    }

    class updateTwitterStatus extends AsyncTask<Void, Void, String> {

        private Intent i = null;

        @Override
        protected String doInBackground(Void... params) {

            ConfigurationBuilder cb = new ConfigurationBuilder();

            cb.setDebugEnabled(true)
                    .setOAuthConsumerKey("V***********")
                    .setOAuthConsumerSecret(
                            "****************");

            TwitterFactory tf = new TwitterFactory(cb.build());
            twitter = tf.getInstance();

            try {
// the next line throws the error
                requestToken = twitter.getOAuthRequestToken(CALLBACK_URL);
                Log.i("bauu", "miao");

                String authUrl = requestToken.getAuthenticationURL();

                startActivity(new Intent(Intent.ACTION_VIEW,
                        Uri.parse(requestToken.getAuthenticationURL())));

                return authUrl;

            } catch (Exception e) {
                e.printStackTrace();
            }
            return null;
        }

    }

    @Override
    public void onResume() {
        super.onResume();
    }

    private void dealWithTwitterResponse(Intent intent) {
        Log.i("Sonod entro", "vau");
        final Uri uri = intent.getData();
        if (uri == null) {
            Log.i("è null", "null");
        }
        Log.i("callback funziona", "ciao");
        if (uri != null && uri.toString().startsWith(CALLBACK_URL)) {
            final String verifier = uri.getQueryParameter("oauth_verifier");
            final String oauthToken = uri.getQueryParameter("oauth_token");
            new Thread(new Runnable() {
                public void run() {
                    try {
                        Log.i("SOno dentro il run", "asd");
                        AccessToken at = twitter.getOAuthAccessToken(
                                requestToken, verifier);

                        twitter.setOAuthAccessToken(at);
                        twitter.updateStatus("CHI VUOLE ESSERE SCIENZIATO?? Punteggio: "
                                + it
                                + " "
                                + frase
                                + " "
                                + "www.scienze-naturali.com");

                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                }
            }).start();
        }

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.punteggio, menu);
        return true;
    }

}

xml 文件是:

我在平板电脑上遇到了同样的错误。我似乎在设备上连接到互联网，但实际上存在连接问题。要修复该错误，我只需在设备上禁用并重新启用 wifi。
