在Android中从服务器获取和发送数据的最佳方法

Question

Hi i am a iPhone developer and new to android. I want to know a best approach in android to make a http connection and get the response from server and (like iOS there are connectionDidFinish, connectionDidFail methods) i want to show a loader when connection is start and when connection is complete then i dismiss the loader. how to do that.

I read about HttpConnection, HttpURLConnection, DefaultHttpClient but i am too confuse that which is best approach and how to use them and one more thing connection is like a asynchronous connection.

one more thing i want to make two or more connection so that i have to differentiate between them also so suggest me that also?

要显示和关闭加载程序（即ProgressBar或ProgressDialog），请实现AsyncTask （在Android中称为无痛线程 ）。
