Is there any way to know, change of wifi network in android?

Question

I'm developing an app. Application restarts when wifi network is switched from netwok-1 to network-2. Problem is that I don't know to detect changing in wifi network. Any help or suggestion would be appreciated.

In general you don't have to take care of the which wifi network is connected, ConnectivityManager will do it on your behalf.

ConnectivityManager cm =
     (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);

NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
boolean isConnected = activeNetwork != null &&
                      activeNetwork.isConnectedOrConnecting();

Now if your app/device(s) changes network state, then you need to monitor the connectivity_change using some broadcast.

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

It'll help you to broadcast only when you've previously suspended updates or downloads in order to resume them.
