安卓2.3.3

重要提示:::我是很新的整合Twitter和Facebook的东西。我有集成新twitter4j我的应用程序的要求，无意中发现了几个例子来制定自己的路。我的要求是获得从时间轴的鸣叫。然而，下面还对示例包含如何更新从应用程序的鸣叫。

Important Note ::: I am very new to integrating twitter and facebook stuff. I had a requirement of integrating new twitter4j to my application and stumbled on few examples to work out my way. My requirement was to get the tweets from the timeline. However, the example below also contains how to update the tweet from the application.

注2 :::我已经使用的例子，从这里和此处。一切归功于这些网站的人。我做了一些改动，它的工作。

Note 2 ::: I have used the examples from here and here. All credit goes to the guys of these sites. I made a couple of changes and it worked.

在code是pretty的多的自我解释，如果您需要任何其他说明，请访问以上网站。

The code is pretty much self explanatory and if you need any other clarifications, please visit the sites above.

下面是我做了什么：

签署了开发账号在Twitter和获得消费者键和消费者的秘密。取代他们在任何你找到消费者的重点和消费者的秘密，在code中的常量。

Signed up for Dev account at Twitter and got "consumer key" and "consumer secret". Replace them where ever you find the constants for consumer key and consumer secret in the code.

从这里下载twitter4j-3.0.3.zip

提取zip文件，从Twitter，3.0.3-> lib中添加库。我已经添加了所有的图书馆，因为我是测试出的整合。您可能要添加都需要你的库。

Extracted the zip file and added the libraries from twitter-3.0.3->lib. I have added all the libraries as I was testing out the integration. You may want to add libraries that are needed for you.

右键点击项目 - >属性 - > Java构建Path-> Libraries->添加罐。进入lib文件夹中的项目并添加所有的库。

Right Click on the project-> Properties->Java Build Path->Libraries->Add Jars. Go to lib folder in the project and add all libraries.

请按照下列步骤，您将应用程序集成与Twitter。

Please follow these steps and you will have the application integrated with twitter.

有关使用该应用程序在Twitter上发布的tweet，我已经使用从的此处。 对于获得的时间表从Twitter，我已经使用的例子这里。

For posting tweet on twitter using the application, I have used the example from here. For getting the timeline from twitter, I have used the example from here.
