ConnectivityManager

I check ConnectivityManager Class.

I get Active network. If active network isn't, app makes exception.

ConnectivityManager cm = (ConnectivityManager)getSystemService(CONNECTIVITY_SERVICE);
NetworkInfo ni = cm.getActiveNetworkInfo();

I print network information.

NetworkInfo.DetailedState dt = ni.getDetailedState();
Log.d("net", "getDetailedState = " + dt);
Log.d("net", "getExtraInfo = " + ni.getExtraInfo());
Log.d("net", "getReason = " + ni.getReason());
NetworkInfo.State st = ni.getState();
Log.d("net", "getState = " + st);
Log.d("net", "getSubtype = " + ni.getSubtype());
Log.d("net", "getSubtypeName = " + ni.getSubtypeName());
Log.d("net", "getType = " + ni.getType());
Log.d("net", "getTypeName = " + ni.getTypeName());
Log.d("net", "isAvailable = " + ni.isAvailable());
Log.d("net", "isConnected = " + ni.isConnected());
Log.d("net", "isConnectedOrConnecting  = " + ni.isConnectedOrConnecting ());
Log.d("net", "isFailover   = " + ni.isFailover  ());
Log.d("net", "isRoaming   = " + ni.isRoaming  ());

This result is 3g mobile active:

 getDetailedState = CONNECTED
 getExtraInfo = dm.jplat.net
 getReason = apnSwitched
 getState = CONNECTED
 getSubtype = 0
 getSubtypeName = UNKNOWN
 getType = 0
 getTypeName = mobile
 isAvailable = false
 isConnected = true
 isConnectedOrConnecting  = true
 isFailover   = false
 isRoaming   = false

This result is wifi active:

 getDetailedState = CONNECTED
 getExtraInfo = null
 getReason = null
 getState = CONNECTED
 getSubtype = 0
 getSubtypeName = 
 getType = 1
 getTypeName = WIFI
 isAvailable = true
 isConnected = true
 isConnectedOrConnecting  = true
 isFailover   = false
 isRoaming   = false
