How to get the wifi configuration file location in android
I'm developing an app that backup the wifi configuration from any android device (rooted) so I want to know how to get the file location in the android device so can I deal with it.
I know there is a lot of location depending on your ROM or device
like /data/wifi/bcm_supp.conf or /data/misc/wifi/wpa_supplicant.conf
but I want to get it dynamically .
You need to create a WifiConfiguration instance like this:
String networkSSID = "test";
String networkPass = "pass";
WifiConfiguration conf = new WifiConfiguration();
conf.SSID = """ + networkSSID + """; //
Then, for WEP network you need to do this:
conf.wepKeys[0] = """ + networkPass + """;
conf.wepTxKeyIndex = 0;
conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
conf.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40);
For WPA network you need to add passphrase like this:
conf.preSharedKey = """+ networkPass +""";
For Open network you need to do this:
conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
Then, you need to add it to Android Wi-Fi manager settings:
WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
wifiManager.add(conf);
And finally, you might need to enable it, so Android connects to it:
List<WifiConfiguration> list = wifiManager.getConfiguredNetworks();
for (WifiConfiguration i : list) {
if (i.SSID != null && i.SSID.equals(""" + networkSSID + """)) {
wm.disconnect();
wm.enableNetwork(i.networkId, true);
wm.reconnect();
break;
}
}
In case of WEP, if your password is in hex, you do not need to surround it with quotation marks.
