一切看起来都不错，但函数retrieveRequestToken() 抛出“OAuthCommunicationException”。例外

Question

我正在尝试构建一个 Android 应用程序，以便它可以在 twitter 中发推文。
我试图使用函数retrieveRequestToken(consumer,CALLBACK_URI) 获取uri，但它会抛出“OAuthCommunicationException”异常。 我授予了该应用程序的互联网使用权限（我已检查过）。我已在 Twitter 上注册了该应用程序，提供读取、写入和直接消息。

这是代码片段

update = (Button) findViewById(R.id.update);
        status = (TextView) findViewById(R.id.status);
private  static  final  String CALLBACK_URI = OauthTwittertwitt;
private static final String REQUEST_TOKEN_URL = httpsapi.twitter.comoauthrequest_token;
private static final String ACCESS_TOKEN_URL = httpsapi.twitter.comoauthaccess_token;
private static final String AUTHORIZE_URL = httpsapi.twitter.comoauthauthorize;
private static CommonsHttpOAuthConsumer consumer;
private static DefaultOAuthProvider provider;
consumer = new CommonsHttpOAuthConsumer(CONSUMER_KEY, CONSUMER_SECRET);
provider = new DefaultOAuthProvider(REQUEST_TOKEN_URL,
                ACCESS_TOKEN_URL, AUTHORIZE_URL);
        update.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                 showMyDialog();

                try {
                    Log.d(in,check1);
                    String authUrl = provider.retrieveRequestToken(consumer,CALLBACK_URI);
                    Log.d(uri, authUrl);
                    startActivity(new Intent(Intent.ACTION_VIEW,Uri.parse(authUrl)));
                } catch (OAuthMessageSignerException e) {
                     TODO Auto-generated catch block
                    Log.d(signerg,1);
                    e.printStackTrace();
                } catch (OAuthNotAuthorizedException e) {
                     TODO Auto-generated catch block
                    Log.d(Notauths,2);
                    e.printStackTrace();
                } catch (OAuthExpectationFailedException e) {
                     TODO Auto-generated catch block
                    Log.d(authExceg,3);
                    e.printStackTrace();
                } catch (OAuthCommunicationException e) {
                     TODO Auto-generated catch block
                    Log.d(communication,4);
                    e.printStackTrace();
                }

            }

这是由主线程上的网络异常引起的。尝试在线程上运行 oauth 代码：

          new Thread(new Runnable() {
                public void run() {
                    String authUrl = provider.retrieveRequestToken(consumer,CALLBACK_URI);
                }
              }).start();
