Como criar e ler programaticamente configurações WEP / EAP WiFi no Android?

Como criar e ler programaticamente WEP/EAP WiFi configurationsno Android?

Tenho visto várias pessoas lutando com essa mesma questão em vários fóruns e em toda a comunidade. Eu sei que isso não é tão direto (especialmente EAP) de descobrir porque quando eu queria conseguir o mesmo, eu também me esforcei bastante. Bem, todo o trabalho árduo de análise de código e pesquisa de várias implementações na internet feito com eu estava finalmente capaz de atingir o objetivo. Todo o crédito vai para vários projetos de código aberto e seus desenvolvedores.

Eu gostaria de compartilhar esse conhecimento com todos, já que o SO encoraja isso: "Também é perfeitamente normal fazer e responder sua própria pergunta, desde que você finja que está no Jeopardy: expresse na forma de uma pergunta."

Parte 1: Criando uma configuração WEP WiFi programaticamente

Isso é muito simples, WifiConfiguration expõe a interface para criar o mesmo. Aqui está o código de exemplo:

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 );  

}

Seguindo as permissões necessárias em 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>

Parte 2: Leia
novamente uma configuração WEP WiFi de forma programática simples. Aqui está o código de exemplo:

    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]);
    }

Parte 3: Leia uma configuração WiFi EAP programaticamente
Agora, isso é complicado. Você pode encontrar o código que salva uma configuração WiFi EAP por meio da interface de usuário do Android vanilla em WifiDialog.java . Bem fácil. Podemos usar o mesmo código em nosso aplicativo, bem, NÃO! Se acontecer de você tentar isso, você receberá erros dizendo não consegue encontrar os símboloseap,phase,client_certe assim por diante. Uma pequena investigação detalhada nos mostra EnterpriseFieldis private dentro daWiFiConfigurationclasse e todos os símbolos que não conseguimos encontrar são do tipoEnterpriseField. Bem, nós encontramos um obstáculo. Precisamos desses campos para ler / salvar uma configuração EAP, mas não temos acesso programático a eles!

Java Reflection APIpara o resgate Bem, eu não sou um especialista em Java, então não entrarei em detalhes da API do Reflection como tal e você pode pesquisar tutoriais no Google ou obter mais informações aqui . Para mantê-lo curto e agradável, o Reflection API permite que você inspecione classes, interfaces, campos e métodos em tempo de execução, sem saber os nomes das classes, métodos etc. em tempo de compilação. Também é possível instanciar novos objetos, invocar métodos e obter / definir valores de campo usando reflexão. E, o mais importante, Reflexão pode ajudá-lo a acessar membros de dados privados dentro de uma classe Bem, é disso que precisamos, não é? :)

Vamos verificar o exemplo de código agora que mostra como ler uma configuração EAP WiFi usando o Reflection Api. Como um bônus, o snippet irá registrar a configuração em um arquivo e salvá-lo no cartão SD ... bem esperto ..eh;) Um pouco de visão geral do Reflection Api e tenho certeza de que entender o código abaixo é fácil.

    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";

Este é o código para criar um arquivo de log no cartão SD antes de chamar a readEapConfig()função.

        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());
        }

Agora, a readEapConfig()própria função:

    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);

Espero que isso ajude alguém. @Android learner Removi a parte sobre adHocFrequency e SSID, pois eles estavam causando travamentos, mas meus resultados ainda eram bons sem eles.

As chaves WEP são mascaradas, portanto não é possível lê-las com o código mencionado

    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]);

Existe alguma maneira de resolver isso da mesma forma que a solução EAP? Com reflexão?
