Kurtis link describes numerous ways of checking the current network state.

To listen for the network change events, your activity must register the broadcast receiver that listens for the CONNECTIVITY_CHANGE:

public void onCreate(Bundle savedInstanceState) {
    registerReceiver(new BroadcastReceiver() {      
        public void onReceive(Context context, Intent intent) {
            Log.i(TAG, "Hey, net?");
        }}, new IntentFilter("android.net.conn.CONNECTIVITY_CHANGE"));
}

You also need to declare your intent filter in the manifest:

        <intent-filter>
            <action android:name="android.net.conn.CONNECTIVITY_CHANGE"/>
        </intent-filter>

and also add android.permission.ACCESS_NETWORK_STATE permission.

This has been asked and answered. See this stackoverflow post for details.

The ACTION_AIRPLANE_MODE_CHANGED is broadcast when ever the airplane mode changes.
