Testing for 4G Networks in Android

In order to test for the presence / absence of WiMax (4G) you need to do something like the following:


private boolean isNetworkAvailable() {
ConnectivityManager connec = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo mobileInfo = connec.getNetworkInfo(0);
NetworkInfo wifiInfo = connec.getNetworkInfo(1);
NetworkInfo wimaxInfo = connec.getNetworkInfo(6);

if (wimaxInfo!=null) {
return mobileInfo.isConnectedOrConnecting() || wifiInfo.isConnectedOrConnecting() || wimaxInfo.isConnectedOrConnecting();
}
else {
return mobileInfo.isConnectedOrConnecting() || wifiInfo.isConnectedOrConnecting();
}
}


A little hard won knowledge from the trenches.
