如何在Android中以编程方式创建和读取
WEP/EAP WiFi configurations我在各个论坛和整个社区看到很多人在这个问题上苦苦挣扎。我知道这并不是那么简单（尤其是 EAP），因为当我想要实现同样的目标时，我也付出了很多努力。嗯，所有代码分析和在互联网上搜索各种实现的艰苦工作都是我完成的终于能够达到目的了。所有的功劳都归功于许多开源项目及其开发人员。
我想与所有人分享这些知识，因为这样鼓励：“只要你假装自己处于危险之中，提出并回答自己的问题也是完全可以的：以问题的形式表达它.”
第 1 部分：以编程方式创建 WEP WiFi 配置
这非常简单，WifiConfiguration公开了创建相同内容的接口。这是示例代码：
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 );
}
遵循AndroidManifest.xml中所需的权限
<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>
第 2 部分：以编程方式读取 WEP WiFi 配置
又直截了当。这是示例代码：
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]);
}
第 3 部分：以编程方式读取 EAP WiFi 配置
现在这很棘手。您可以在 WifiDialog.java 中找到通过普通 Android UI 保存 EAP WiFi 配置的代码。很简单我们可以在我们的应用程序中使用相同的代码，当然不！如果您碰巧尝试此操作，您会收到错误消息，提示找不到符号
eapphaseclient_cert is private类中存在EnterpriseField
WiFiConfigurationEnterpriseFieldJava Reflection API现在让我们检查一下代码示例，它展示了如何使用 Reflection Api 读取 EAP WiFi 配置。作为奖励，该代码片段会将配置记录到文件中并将其保存在 SD 卡上....非常流畅..eh ;) 对 Reflection Api 进行一些概述，我确信掌握下面的代码很容易。
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";
这是在调用
readEapConfig() 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());
}
现在是

Android 在 JellyBean 4.3 中添加了 API。如果您想在 API 18 上配置 WIFI，则必须使用此选项：
http://developer.android.com/reference/android/net/wifi/WifiEnterpriseConfig.html
第 4 部分让我走上了正确的道路！不过，我想创建一个 TTLS 而不是 TLS 配置，这就是我的做法！

希望这对某人有所帮助。 @Android 学习者我删除了有关 adHocFrequency 和 SSID 的部分，因为它们会导致崩溃，但没有它们我的结果仍然很好。
WEP 密钥被屏蔽，因此无法使用上述代码读取它们
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]);
有没有办法像EAP解决方案一样解决这个问题？ 有反思吗？
