Android: How to share with Twitter (如何分享信息到Twitter)

逐步补全！

决定使用twitter4j来完成。

完成过程：

step1: 从 http://abhinavasblog.blogspot.com/2011/06/for-all-my-code-thirsty-friends-twitter.html?spref=fb

check out 出代码：

设置： 

/** Called when the activity is first created. */

privatestaticfinal StringCONSUMER_KEY ="XXXXXXXXXXXXXXX";// 

privatestaticfinal StringCONSUMER_SECRET ="XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";

修改manifest.xml

<applicationandroid:icon="@drawable/icon"android:label="@string/app_name">

<activityandroid:name=".TwitterForUActivity"android:label="@string/app_name">

<intent-filter>

<actionandroid:name="android.intent.action.MAIN"/>

<categoryandroid:name="android.intent.category.LAUNCHER"/>

</intent-filter>

    <intent-filter>

            <actionandroid:name="android.intent.action.VIEW"/>

            <categoryandroid:name="android.intent.category.DEFAULT"/>

            <categoryandroid:name="android.intent.category.BROWSABLE"/>

            <dataandroid:scheme="twitterapp"android:host="connect"/>

        </intent-filter>

        

</activity>

</application>

<uses-permissionandroid:name="android.permission.INTERNET"/>

// 红色部分为添加

在真机上测试运行，结果显示：

然后查阅资料：

http://java.dzone.com/articles/learning-android

还是解决不了，不知道应该如何是好。

换一种思路：

http://android10.org/index.php/articleslibraries/291-twitter-integration-in-your-android-application

按照这个上面的指导一步一步来做，试试运气吧！ 结果还是不行。

后来才知道是网络出了问题，公司的wifi有问题！上的异常，也是由于网络问题所引起的，在开发 ”分享信息到twitter上“，这个功能时，一定要保证你的手机能够连接VPN上得twitter,facebook这些外网。

还是使用原来的步骤来做，就成功了。

特别注意： 在twitter上面创建自己的应用 时，一定要记得设置 CALLBACK_URL 这个项目，不能为空。对于ANDROID 来说这个设置一定不能为空。你可以随便设置一个网址，反正在程序里面我们已经做了CALLBACK处理。所以设置什么内容是无关的。或者出现下面的异常，也是因为网络原因：
