我在我的應用程序中實現了Twitter，我在回調中遇到問題。Android中的Twitter中的回調問題
Twitter API的最近更新，所以我無法發送回叫URL。
此外，設置頁面現在改變，沒有選擇基於Web的應用程序或桌面應用程序的選項。
如果我在這一行發送回叫：
authUrl = provider.retrieveRequestToken(consumer,CALLBACK_URL);
它總是返回
oauth.signpost.exception.OAuthNotAuthorizedException: Authorization failed (server replied with a 401). This can happen if the consumer key was not correct or the signatures did not match.
，但如果我的重定向發送爲空在這個給Twitter登錄頁面，但經過成功授權它不會返回到我的應用程序。
在顯示PIN號後，我想重定向回我的應用程序。
注意：Twitter已經更新了他們的API，因此Post中的舊代碼無法使用。
我嘗試了所有以下鏈接
Link 1， Link 2， Link 3， Link4， Link5， Link 6
我的代碼如下：
public class Main extends Activity {
OAuthConsumer consumer;
OAuthProvider provider;
Twitter twitter;
private static String CALLBACK_URL = "twitterapptest://connect";
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);
consumer = new DefaultOAuthConsumer(
"XXXXXXXXXXX",
"XXXXXXXXXXXXX");
provider = new DefaultOAuthProvider(
"https://api.twitter.com/oauth/request_token",
"https://api.twitter.com/oauth/access_token",
"https://api.twitter.com/oauth/authorize");
String authUrl = null;
try {
authUrl = provider.retrieveRequestToken(consumer,null);
this.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(authUrl)));
} catch (OAuthMessageSignerException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (OAuthNotAuthorizedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (OAuthExpectationFailedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (OAuthCommunicationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String pin = null;
try {
pin = br.readLine();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
provider.retrieveAccessToken(consumer, "4947222");
} catch (OAuthMessageSignerException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (OAuthNotAuthorizedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (OAuthExpectationFailedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (OAuthCommunicationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
URL url = null;
try {
url = new URL("http://twitter.com/statuses/mentions.xml");
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
HttpURLConnection request = null;
try {
request = (HttpURLConnection) url.openConnection();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
consumer.sign(request);
} catch (OAuthMessageSignerException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (OAuthExpectationFailedException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (OAuthCommunicationException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
try {
request.connect();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
System.out.println("Response: " + request.getResponseCode() + " "
+ request.getResponseMessage());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
/**

*/
@Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
Uri uri = intent.getData();
if (uri != null && uri.toString().startsWith(CALLBACK_URL)) {
String verifier = uri
.getQueryParameter(oauth.signpost.OAuth.OAUTH_VERIFIER);
try {
// this will populate token and token_secret in consumer
provider.retrieveAccessToken(consumer,
verifier);
// TODO: you might want to store token and token_secret in you
// app settings!!!!!!!!
AccessToken a = new AccessToken(consumer.getToken(),
consumer.getTokenSecret());
// initialize Twitter4J
twitter = new TwitterFactory().getInstance();
twitter.setOAuthConsumer("XXXXXXX", "XXXXXXXXXX");
twitter.setOAuthAccessToken(a);
// create a tweet
Date d = new Date(System.currentTimeMillis());
String tweet = "#OAuth working! " + d.toLocaleString();
// send the tweet
twitter.updateStatus(tweet);
} catch (Exception e) {
Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show();
}
}
}
}
我的清單：

401錯誤可能是由幾件事引起的。特別是，檢查您的API密鑰是否正確（沒有多餘的空格或缺少字符），並檢查設備上的日期/時間和時區是否正確。 – Dave
