[解決済み] AndroidでWEP/EAP WiFiの設定をプログラムで作成し、読み取るには?

2022-10-04 17:36:03

質問内容

どのようにプログラム的に WEP/EAP WiFi configurations をプログラムで作成する方法は?

私は、さまざまなフォーラムやコミュニティ全体のこの非常に質問に苦労している人々の数を見てきました。私が同じことを実現したかったとき、私もかなり苦労したので、これは把握するのが簡単ではない (特に EAP)ことを私は知っています。すべての功績は、多くのオープン ソース プロジェクトとその開発者のおかげです。

私はこの知識をみんなと共有したいと思います。 励ます のように、質問して答えることもできます。

その1。 プログラムでWEP WiFiの設定を作成する。

第2部です。 WEP WiFiの設定をプログラム的に読み取る。

その3. EAP WiFiの設定をプログラム的に読み取る。

その4. EAP WiFiの設定をプログラム的に保存する。

どのように解決するのですか?

パート1: プログラムによるWEP WiFi設定の作成

これはかなりわかりやすいですね。 WifiConfiguration は、同じものを作成するためのインターフェイスを公開しています。以下はサンプルコードです。

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 );  

}

AndroidManifest.xmlで必要なパーミッションに従う。

    <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: プログラムでWEP WiFiの設定を読み込む

再びStraighforward。以下はサンプルコードです。

    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: プログラムでEAP WiFiの設定を読み込む

さて、これはトリッキーです。EAP WiFiの設定をバニラAndroid UIから保存するコードは、以下の場所にあります。 WifiDialog.java . さて、簡単ですね。私たちのアプリケーションで同じコードを使用することができます、さてNO! もしこれを試そうとすると、シンボルが見つからないというエラーが発生します。 eap , phase , client_cert といった具合です。少し詳しく調べてみると エンタープライズフィールド is private 内部 WiFiConfiguration クラスの中にあり、見つからないシンボルはすべて EnterpriseField . EAP設定の読み取り/保存にこれらのフィールドが必要ですが、プログラム的にアクセスすることはできません!

Java Reflection API 救助に 私はJavaの専門家ではないので、Reflection APIの詳細には触れませんが、チュートリアルやより詳しい情報を得るためにググってみてください。 ここで . Reflection API を使用すると、コンパイル時にクラスやメソッドなどの名前を知らなくても、実行時にクラス、インターフェース、フィールド、メソッドを検査することができます。また、リフレクションを使って新しいオブジェクトをインスタンス化し、メソッドを呼び出し、フィールドの値を取得/設定することが可能です。 Reflectionはクラス内のプライベートなデータメンバにアクセスするのに役立ちます。 まあこれは私たちが必要とするものですね :)

Reflection API を使用して EAP WiFi 設定を読み取る方法を示すコード例を確認してみましょう。ボーナスとして、このスニペットは設定をファイルに記録し、SD カードに保存します...かなり巧妙です...えっ ;) Reflection Apiの概要を少し説明すれば、以下のコードを理解するのは簡単だと思います。

    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";

を呼び出す前に、SDカードにログファイルを作成するためのコードです。 readEapConfig() 関数を呼び出す前に、SDカードにログファイルを作成するコードです。

        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());
        }

ここで readEapConfig() 関数そのものです。

    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);
