How to detect android app when it detects a wifi

Question

I want my app to detect the wifi that is connected.

For example, i wanna know how the app can connect to wifi and tell me that it has already been connected.

@AlexandreSantos actually i found some codes here but I dont have any idea where to put. — heyholetsgobaby, Jul 09 '14 at 09:25

public class WiFiChangeBroadcastReceiver extends BroadcastReceiver {

    private String LOGTAG = getClass().getSimpleName();

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d(LOGTAG, "WiFi Status Changed");
        if (intent.getAction().equals(WifiManager.NETWORK_STATE_CHANGED_ACTION)) {
            NetworkInfo networkInfo = intent
                    .getParcelableExtra(WifiManager.EXTRA_NETWORK_INFO);
            if (networkInfo.isConnected()) {
                Log.d(LOGTAG,
                        "Wifi is connected: " + String.valueOf(networkInfo));
            }
        }
    }
}

Android Manifest :

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

also explain how can we call it.Or it is automatically called. – Zar E Ahmer Jul 09 '14 at 06:02
Well, its a broadcast receiver so the onReceive method will be automatically called when the WiFi State changes. – Shivam Verma Jul 09 '14 at 06:03
@ShivamVerma hi! thanks for the ans, but i am a noob in making an app, may i know where to put the codes or maybe you can copy and paste the whole coding in a java project? – heyholetsgobaby Jul 09 '14 at 09:27
Well, just create a new Java file named WiFiChangeBroadcastReceiver in the src folder and add the first part of code in it. Add the second part to your android manifest just after the tag. – Shivam Verma Jul 09 '14 at 09:30
@ShivamVermaisit java package or java class?? Thanks im so sorry i am very new! – heyholetsgobaby Jul 10 '14 at 01:49
create the java class inside the package. – Shivam Verma Jul 10 '14 at 01:51
@ShivamVerma I'm sorry can I put this code inside protected void onStart()? – heyholetsgobaby Jul 10 '14 at 02:38
You'll need to go through the basic of android app development and java at the same time. It'll be impossible to help you out to this level. Apologies. – Shivam Verma Jul 10 '14 at 03:02
@heyholetsgobaby So, did anything work ? – Shivam Verma Jul 13 '14 at 04:17
@ShivamVerma it says wifi status change but never print out the `Wifi is connected: " + String.valueOf(networkInfo));` whenever i change to another ssid – heyholetsgobaby Jul 15 '14 at 01:50
