Hi Thierry,
Implement a broadcast receiver which listens for the event
android.net.wifi.supplicant.CONNECTION_CHANGE.
This is from the API description
* Broadcast intent action indicating that a connection to the
supplicant has
* been established (and it is now possible
* to perform Wi-Fi operations) or the connection to the
supplicant has been
* lost. One extra provides the connection state as a boolean,
where {...@code true}
* means CONNECTED.
You will find all supported intents in the following file
frameworks/base/wifi/java/android/net/wifi/WifiManager.java
Of course also more information on the Android API pages
http://developer.android.com/reference/android/net/wifi/WifiManager.html#SUPPLICANT_CONNECTION_CHANGE_ACTION
The following code is from frameworks/base/services/java/com/android/
server/WifiWatchdogService.java.
/**
* Registers to receive the necessary Wi-Fi broadcasts.
*/
private void registerForWifiBroadcasts() {
IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction
(WifiManager.NETWORK_STATE_CHANGED_ACTION);
intentFilter.addAction
(WifiManager.SUPPLICANT_CONNECTION_CHANGE_ACTION);
intentFilter.addAction(WifiManager.WIFI_STATE_CHANGED_ACTION);
mContext.registerReceiver(mReceiver, intentFilter);
}
....
@Override
public void onReceive(Context context, Intent intent) {
final String action = intent.getAction();
if (action.equals
(WifiManager.NETWORK_STATE_CHANGED_ACTION)) {
handleNetworkStateChanged(
(NetworkInfo) intent.getParcelableExtra
(WifiManager.EXTRA_NETWORK_INFO));
} else if (action.equals
(WifiManager.SUPPLICANT_CONNECTION_CHANGE_ACTION)) {
handleSupplicantConnectionChanged(
intent.getBooleanExtra
(WifiManager.EXTRA_SUPPLICANT_CONNECTED, false));
} else if (action.equals
(WifiManager.WIFI_STATE_CHANGED_ACTION)) {
handleWifiStateChanged(intent.getIntExtra
(WifiManager.EXTRA_WIFI_STATE,
WifiManager.WIFI_STATE_UNKNOWN));
}
}
Let me know, if this was helpful.
