万物似乎确定，但功能retrieveRequestToken（）抛出“OAuthCommunicationException'例外 [英] Everythings seems ok but function retrieveRequestToken() throws 'OAuthCommunicationException' exception

问题描述

我想，使其在叽叽喳喳的鸣叫建立一个Android应用程序。

我试图让使用功能retrieveRequestToken（消费者，CALLBACK_URI），URI，但它抛出OAuthCommunicationException'例外。
我给了互联网使用许可应用程序（我已经检查了）。我已经在registerd叽叽喳喳给读应用程序，写和直接的信息。

解决方案

这是通过在主线程异常的网络造成的。尝试在一个线程运行的OAuth code：

 新主题（新的Runnable（）{
                公共无效的run（）{
                    字符串authUrl = provider.retrieveRequestToken（消费者，CALLBACK_URI）;
                }
              }）。开始（）;
 

I am trying to build an android app so that it tweets in twitter.
I am trying to get uri using the function retrieveRequestToken(consumer,CALLBACK_URI) but it throws 'OAuthCommunicationException' exception. I gave the internet uses permission for the application( i have checked it ).I have registerd the app in twitter giving read,write and direct messages.

Here is the code snippet

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;

        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();
                }

            }

解决方案

This is caused by a network on main thread exception. Try running the oauth code on a thread:

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