Network Utility

Peace of code for network connectivity.

Here is the static method for network related operation like
   

• Check network availability
• Get network information
• Connected to WiFi
• Connected to mobile
• Check connection speed like connectivity is fast, slow or medium

You can add below static method in your own util class.

/**
	* Get the network info
	* @param context
	* @return
	*/
	public static NetworkInfo getNetworkInfo(Context context){
	ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
	return cm.getActiveNetworkInfo();

	* Check if there is any connectivity
	* @param context
	* @return
	*/
	public static boolean isConnected(Context context){
	NetworkInfo info = Connectivity.getNetworkInfo(context);
	return (info != null && info.isConnected());
	}
