我已经写了代码来整合Twitter在android.In我得到第一个scrren当我写一些消息给twitt并点击twitt按钮我得到以下异常作为OauthCommunication Exception与服务的通信提供者失败。我已正确输入消费者密钥消费者。

尝试另一种方法在您的应用中整合Twitter
代码（在网络视图中打开网址）
twitter = new TwitterFactory().getInstance();
twitter.setOAuthConsumer(TwitterConstants.CONSUMER_KEY,
TwitterConstants.CONSUMER_SECRET);
RequestToken requestToken = null;
try {
requestToken = twitter.getOAuthRequestToken();
System.out.println("requesttoken"+requestToken);
} catch (TwitterException e) {
e.printStackTrace();
}
twitterUrl = requestToken.getAuthorizationURL();
ConfigurationBuilder builder = new ConfigurationBuilder();
builder.setOAuthAccessToken(TwitterConstants.ACCESS_TOKEN);
builder.setOAuthAccessTokenSecret(TwitterConstants.ACCESS_TOKEN_SECRET);
builder.setOAuthConsumerKey(TwitterConstants.CONSUMER_KEY);
builder.setOAuthConsumerSecret(TwitterConstants.CONSUMER_SECRET);
OAuthAuthorization auth = new OAuthAuthorization(builder.build());
twitter = new TwitterFactory().getInstance(auth);
try {
twitter.updateStatus("Hello World!");
} catch (TwitterException e) {
System.err.println("Error occurred while updating the status!");
}
2。按钮单击（不使用身份验证）
String message="";
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse("http://twitter.com/?status=" + Uri.encode(message)));
startActivity(i);
