In this tutorial how to check network status, Wifi status and mobile network status from \u00a0an Android Application is shown.<\/p>\n
To connect with network most android applications use HTTP for sending and receiving the data.<\/p>\n
It has two basic clients HttpURLConnection and ApacheHttpClient.<\/p>\n
For Gingerbread and higher version we use HttpURLConnection as a client.<\/p>\n
For checking network connection we have 2 methods getActiveNetworkInfo() method and isConnected() method.<\/p>\n
Code:<\/p>\n
