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 www blogs /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
