How to catch on Wifi Change?

Question

I'm developing an app without GUI. It should start it's service when Wifi button is changed(ON or OFF). This is my manifest file:

 <receiver android:name="com.updater.wifitester.NetWatcher">
        <intent-filter  
            android:priority="100">
        <action 
            android:name="android.net.wifi.WIFI_STATE_CHANGED"
            android:enabled="true"
            />

        </intent-filter>
    </receiver>

Here is the permissions that I gave:

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.INTERNET"/>

And I extended Broadcast receiver:

  public class NetWatcher extends BroadcastReceiver {
        @Override
        public void onReceive(Context context, Intent intent) {
        if (WifiManager.WIFI_STATE_CHANGED_ACTION.equals(intent.getAction())) {
                //check intents and service to know if all is ok then set bWifiStateOk accordingly
                Toast.makeText(context, "Wifi on", Toast.LENGTH_LONG).show(); 
                Log.i("wifi_state_changed","wifi changed...");
            } else {
                return ; // do nothing ... we're not in good intent context doh !
            }
    }
}

But there is nothing in the log cat and no Toasts shown. What Am I missing? Please help me guys...

Try this

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

The toast will be shown if connectivity is changed, right? – GOBINATH.M Feb 13 '14 at 16:43
Its preferred to use Logcat to print better than Toast. – mostafa_zakaria Feb 19 '14 at 12:42
