关于Twitter这一块，自发这篇博文之后有很多人问我，有的验证成功了不跳转，或者其它原因什么的，我看了一下，这篇博文里面有写呀，下面以红色粗体文字注明一下
刚进公司，叫我先学习Twitter和Facebook，就类似于国内的微博，或者分享功能，点击某个按钮，出来一个提示框，可以分享到某些地方，这里实现的就是分享到Twitter，当然得要使用代理，因为这是给老外做的，所以得符合他们的习惯
先说一下实现的功能吧，首先运行的时候，会检查是否登陆twitter（通过SharedPreference文件保存登陆状态），如果没有登陆的话会跳转到twitter的登陆认证页面，提示用户输入用户名和密码，这些就是OAuth认证的步骤，不懂的看这儿http://www.cnblogs.com/and_he/archive/2011/05/22/2053477.html
做过新浪微博的都应该知道，首先要申请成为开发者，创建自己的应用，然后会给你一些比如Consumer key和Consumer secret之类的东西，这些东西要先记下来，代码里面要用到的，其余的不啰嗦了，只是要注意一点，创建Twitter应用的时候造成不能忘了填那个Callback URL，我当初就没填，结果整了几天都整不出来结果，也算是我的一点经验吧，下面贴代码，以便于以后查阅
首先我们要用到Twitter封闭好的一些包，这里用到两个twitter4j-core-android和twitter4j-media-support-android，百度一下就出来了
以下是工程目录结构
package
com.twitter;
public class CONST {
public static final String CONSUMER_KEY = " IFkj4coaZ9F9Ngfoe1LFuQ " ;
public static final String CONSUMER_SECRET = " HN2NfE4mtL7OqJaUirWfRnK9XKhyWG2vZmAj6AFwfJ8 " ;
public static final String REQUEST_TOKEN_URL = " https://api.twitter.com/oauth/request_token " ;
public static final String ACCESS_TOKEN_URL = " https://api.twitter.com/oauth/access_token " ;
public static final String CALLBACK_URL = " https://api.twitter.com/oauth/authorize " ;
public static final String TWITPIC_API_KEY = " a77709ebb6c51de0e77f723751a5f9a4 " ;
}
public class CONST {
public static final String CONSUMER_KEY = " IFkj4coaZ9F9Ngfoe1LFuQ " ;
public static final String CONSUMER_SECRET = " HN2NfE4mtL7OqJaUirWfRnK9XKhyWG2vZmAj6AFwfJ8 " ;
public static final String REQUEST_TOKEN_URL = " https://api.twitter.com/oauth/request_token " ;
public static final String ACCESS_TOKEN_URL = " https://api.twitter.com/oauth/access_token " ;
public static final String CALLBACK_URL = " https://api.twitter.com/oauth/authorize " ;
public static final String TWITPIC_API_KEY = " a77709ebb6c51de0e77f723751a5f9a4 " ;
}
