通过Android的AccountManager类进行Twitter身份验证

我所理解的是,如果在用户的设备上安装了官方的Android Twitter应用程序,那么我们可以使用账户经理进行身份验证,如果没有安装,则显示twitter登录网页.

我的理解是否正确？

现在使用twitter web登录页面进行身份验证工作正常.但是如何使用客户经理登录？

使用AccountsType作为“com.twitter.android.auth.login”
我使用来自的客户经理获得了令牌和令牌秘密
•com.twitter.android.oauth.token
•com.twitter.android.oauth.token.secret

我正在使用Twitter4J,并使用我的CONSUMER_KEY& CONSUMER_SECRET和recvd.令牌.但身份验证始终失败.

CONSUMER_KEY& CONSUMER_SECRET是我在twitter上注册应用程序时获得的密钥…但我不明白如何在官方Android Twitter应用程序身份验证中使用这些密钥？

PLS.让我知道谢谢

这是我的代码

public class Twitterauthentication {    
    private static final String TAG = "Twitterauthentication";
    private static final int MSG_GOT_AUTH_TOKEN = 100;
    private static final int MSG_GOT_AUTH_SECRET = 101;
