android check network connection status

In Android, network programming can be implemented in multiple ways: Create a URL and use URLConnection/HttpURLConnection Use HttpClientUse WebView Create a URL and use URLConnection/HttpURLConnection Java.net. * provides basic functions for accessing the HTTP service. The basic operations for using these interfaces include: Create URL and URLConnection/HttpURLConnection object 1. Set
