How to programatically create and read WEP/EAP WiFi configurations in Android?

How to programatically create and read

WEP/EAP WiFi configurations
in Android?

I have seen a number of people struggling on this very question on various forums and all across the community. I know this is not that straight forward(especially EAP) to figure out because When I wanted to acheive the same I too struggled quite a lot.Well, all the hard work of code analysis and searching various implementations on the internet done with I was finally able to acheive the goal. All the credit goes to number of open source projects and their developers.

I would like to share this knowledge with all, Since SO encourages this: "It's also perfectly fine to ask and answer your own question, as long as you pretend you're on Jeopardy: phrase it in the form of a question."

Answer

Part 1: Creating a WEP WiFi configuration programatically

This is pretty much straightforward, WifiConfiguration exposes the interface to create the same. Here is the sample code:

void saveWepConfig()
{
    WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
    WifiConfiguration wc = new WifiConfiguration(); 
    wc.SSID = "\"SSID_NAME\""; //IMP! This should be in Quotes!!
    wc.hiddenSSID = true;
    wc.status = WifiConfiguration.Status.DISABLED;     
    wc.priority = 40;
    wc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
    wc.allowedProtocols.set(WifiConfiguration.Protocol.RSN); 
    wc.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
    wc.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);
    wc.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.SHARED);
    wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
    wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
    wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40);
    wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP104);

    wc.wepKeys[0] = "\"aaabbb1234\""; //This is the WEP Password
    wc.wepTxKeyIndex = 0;

    WifiManager  wifiManag = (WifiManager) this.getSystemService(WIFI_SERVICE);
    boolean res1 = wifiManag.setWifiEnabled(true);
    int res = wifi.addNetwork(wc);
    Log.d("WifiPreference", "add Network returned " + res );
    boolean es = wifi.saveConfiguration();
    Log.d("WifiPreference", "saveConfiguration returned " + es );
    boolean b = wifi.enableNetwork(res, true);   
    Log.d("WifiPreference", "enableNetwork returned " + b );  

}

Following the permissions needed in AndroidManifest.xml

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

Part 2: Read a WEP WiFi configuration programatically
Straighforward again. Here is the sample code:

    void readWepConfig()
    { 
        WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE); 
        List<WifiConfiguration> item = wifi.getConfiguredNetworks();
        int i = item.size();
        Log.d("WifiPreference", "NO OF CONFIG " + i );
        Iterator<WifiConfiguration> iter =  item.iterator();
        WifiConfiguration config = item.get(0);
        Log.d("WifiPreference", "SSID" + config.SSID);
        Log.d("WifiPreference", "PASSWORD" + config.preSharedKey);
        Log.d("WifiPreference", "ALLOWED ALGORITHMS");
        Log.d("WifiPreference", "LEAP" + config.allowedAuthAlgorithms.get(AuthAlgorithm.LEAP));
        Log.d("WifiPreference", "OPEN" + config.allowedAuthAlgorithms.get(AuthAlgorithm.OPEN));
        Log.d("WifiPreference", "SHARED" + config.allowedAuthAlgorithms.get(AuthAlgorithm.SHARED));
        Log.d("WifiPreference", "GROUP CIPHERS");
        Log.d("WifiPreference", "CCMP" + config.allowedGroupCiphers.get(GroupCipher.CCMP));
        Log.d("WifiPreference", "TKIP" + config.allowedGroupCiphers.get(GroupCipher.TKIP));
        Log.d("WifiPreference", "WEP104" + config.allowedGroupCiphers.get(GroupCipher.WEP104));
        Log.d("WifiPreference", "WEP40" + config.allowedGroupCiphers.get(GroupCipher.WEP40));
        Log.d("WifiPreference", "KEYMGMT");
        Log.d("WifiPreference", "IEEE8021X" + config.allowedKeyManagement.get(KeyMgmt.IEEE8021X));
        Log.d("WifiPreference", "NONE" + config.allowedKeyManagement.get(KeyMgmt.NONE));
        Log.d("WifiPreference", "WPA_EAP" + config.allowedKeyManagement.get(KeyMgmt.WPA_EAP));
        Log.d("WifiPreference", "WPA_PSK" + config.allowedKeyManagement.get(KeyMgmt.WPA_PSK));
        Log.d("WifiPreference", "PairWiseCipher");
        Log.d("WifiPreference", "CCMP" + config.allowedPairwiseCiphers.get(PairwiseCipher.CCMP));
        Log.d("WifiPreference", "NONE" + config.allowedPairwiseCiphers.get(PairwiseCipher.NONE));
        Log.d("WifiPreference", "TKIP" + config.allowedPairwiseCiphers.get(PairwiseCipher.TKIP));
        Log.d("WifiPreference", "Protocols");
        Log.d("WifiPreference", "RSN" + config.allowedProtocols.get(Protocol.RSN));
        Log.d("WifiPreference", "WPA" + config.allowedProtocols.get(Protocol.WPA));
        Log.d("WifiPreference", "WEP Key Strings");
        String[] wepKeys = config.wepKeys;
        Log.d("WifiPreference", "WEP KEY 0" + wepKeys[0]);
        Log.d("WifiPreference", "WEP KEY 1" + wepKeys[1]);
        Log.d("WifiPreference", "WEP KEY 2" + wepKeys[2]);
        Log.d("WifiPreference", "WEP KEY 3" + wepKeys[3]);
    }

Part 3: Read a EAP WiFi Configuration programatically
Now this is tricky. You can find the code which saves a EAP WiFi configuration through the vanilla Android UI in WifiDialog.java. Well easy enough We can use the same code in our Application, Well NO! If you happen to try this you will get errors saying cannot find the symbols eap, phase, client_cert and so on. A little detailed investigation tells us EnterpriseFieldis private inside WiFiConfiguration class and all the symbols we cannot find are of the type EnterpriseField. Well we've hit a roadblock, We need these fields for reading/saving a EAP config but we don't have programmatic access to them!

Java Reflection API to the rescue Well I am not a Java expert so I wont be getting in to details of Reflection API as such and you can google for tutorials or get more information here. To keep it Short and Sweet, Reflection API allows you to inspect classes, interfaces, fields and methods at runtime, without knowing the names of the classes, methods etc. at compile time. It is also possible to instantiate new objects, invoke methods and get/set field values using reflection.And, Importantly Reflection can help you access private data members inside a class Well this is what we need don't we? :)

Let's check the code example now which shows how to read a EAP WiFi configuration using Reflection Api. As a bonus the snippet will log the config to a file and save it on the SD Card....pretty slick ..eh ;) A little bit of overview of Reflection Api and I am sure grasping the code below is easy.

    private static final String INT_PRIVATE_KEY = "private_key";
    private static final String INT_PHASE2 = "phase2";
    private static final String INT_PASSWORD = "password";
    private static final String INT_IDENTITY = "identity";
    private static final String INT_EAP = "eap";
    private static final String INT_CLIENT_CERT = "client_cert";
    private static final String INT_CA_CERT = "ca_cert";
    private static final String INT_ANONYMOUS_IDENTITY = "anonymous_identity";
    final String INT_ENTERPRISEFIELD_NAME = "android.net.wifi.WifiConfiguration$EnterpriseField";

This is the code to create a logfile on to SD card before calling the readEapConfig() function.

        BufferedWriter out = null;
        try 
        {
            File root = Environment.getExternalStorageDirectory();
            Toast toast = Toast.makeText(this, "SD CARD mounted and writable? " + root.canWrite(), 5000);
            toast.show();
            if (root.canWrite())
            {
                File gpxfile = new File(root, "ReadConfigLog.txt");
                FileWriter gpxwriter = new FileWriter(gpxfile);
                out = new BufferedWriter(gpxwriter);
                out.write("Hello world");
                //out.close();
            }
        } catch (IOException e) 
        {
            Toast toast = Toast.makeText(this, "Problem reading SD CARD", 3000);
            Toast toast2 = Toast.makeText(this, "Please take logs using Logcat", 5000);
            Log.e("<<<<<<<<<<WifiPreference>>>>>>>>>>>>", "Could not write file " + e.getMessage());
        }

Now the readEapConfig() function itself:

    void readEapConfig(BufferedWriter out)
    {
        /*Get the WifiService */        
        WifiManager wifi = (WifiManager)getSystemService(WIFI_SERVICE);
        /*Get All WIfi configurations*/
        List<WifiConfiguration> configList = wifi.getConfiguredNetworks();
        /*Now we need to search appropriate configuration i.e. with name SSID_Name*/
        for(int i = 0;i<configList.size();i++)
        {
            if(configList.get(i).SSID.contentEquals("\"SSID_NAME\""))
            {
                /*We found the appropriate config now read all config details*/
                Iterator<WifiConfiguration> iter =  configList.iterator();
                WifiConfiguration config = configList.get(i);

                /*I dont think these fields have anything to do with EAP config but still will
                 * print these to be on safe side*/
                try {
                Log.d("<<<<<<<<<<WifiPreference>>>>>>>>>>>>", "[SSID]" + config.SSID);
                out.write("<<<<<<<<<<WifiPreference>>>>>>>>>>>>" + "[SSID]" + config.SSID);
