I can enumerate all wifi networks in range (using startScan + SCAN_RESULTS_AVAILABLE_ACTION + getScanResults) and get their SSID and BSSID values, but I can't figure out how to determine the security type of each network.
In my main object:
IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION);
registerReceiver(scanReceiver, intentFilter);
((WifiManager)getSystemService(Context.WIFI_SERVICE)).startScan();
In my scanReceiver object:
public void onReceive(Context c, Intent intent) {
if (WifiManager.SCAN_RESULTS_AVAILABLE_ACTION.equals(intent.getAction())){
mainObject.scanComplete();
}
}
And again in my main object:
public void scanComplete()
{
List<ScanResult> networkList = ((WifiManager)getSystemService.(Context.WIFI_SERVICE)).getScanResults();
for (ScanResult network : networkList)
{
<do stuff>
}
}
The code works insofar that scanComplete eventually gets called, and I can successfully enumerate all nearby wifi networks and get their SSID and BSSID, but I can't figure out how to determine their security type.
Is there a way to do this?
Thanks in advance.
I think you can find it in the source code of Settings.apk.
First you should call wifiManager.getConfiguredNetworks()
or wifiManager.getScanResults()
,
then use the two methods below: (find them in AccessPoint class "com.android.settings.wifi"
):
static int getSecurity(WifiConfiguration config) {
if (config.allowedKeyManagement.get(KeyMgmt.WPA_PSK)) {
return SECURITY_PSK;
}
if (config.allowedKeyManagement.get(KeyMgmt.WPA_EAP) ||
config.allowedKeyManagement.get(KeyMgmt.IEEE8021X)) {
return SECURITY_EAP;
}
return (config.wepKeys[0] != null) ? SECURITY_WEP : SECURITY_NONE;
}
static int getSecurity(ScanResult result) {
if (result.capabilities.contains("WEP")) {
return SECURITY_WEP;
} else if (result.capabilities.contains("PSK")) {
return SECURITY_PSK;
} else if (result.capabilities.contains("EAP")) {
return SECURITY_EAP;
}
return SECURITY_NONE;
}
Hope this is helpful.
