主要是通过反射读取wifi配置信息，不过6.0开始不能修改代理了，会校验权限，只有系统应用权限可以修改。
WifiManager manager = (WifiManager) context
.getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = manager.getConnectionInfo();
List<WifiConfiguration> configs = manager.getConfiguredNetworks();
if (configs == null) {
return false;
}
for (WifiConfiguration wifiConfiguration : configs) {
if (wifiConfiguration.SSID.equals("\"" + wifiInfo.getSSID() + "\"")
|| wifiConfiguration.SSID.equals(wifiInfo.getSSID())) {
if (Build.VERSION.SDK_INT > 20) {
try {
Method getProxyMethod = WifiConfiguration.class.getDeclaredMethod("getHttpProxy");
if (getProxyMethod != null) {
Object state = getProxyMethod.invoke(wifiConfiguration);
if (state == null)
return false;
Field actualhost = ProxyInfo.class.getDeclaredField("mHost");
actualhost.setAccessible(true);
Object actualhostStr = actualhost.get(state);
return actualhostStr != null && actualhostStr.equals(host);
}
} catch (NoSuchMethodException | IllegalAccessException
| IllegalArgumentException
| InvocationTargetException
e) {
return false;
} catch (NoSuchFieldException e) {
e.printStackTrace();
return false;
}
} else if (Build.VERSION.SDK_INT > 14) {
try {
Field linkPropertiesField = WifiConfiguration.class
.getDeclaredField("linkProperties");
linkPropertiesField.setAccessible(true);
Object linkProperties = linkPropertiesField.get(wifiConfiguration);
Class linkPropertiesClass = Class.forName("android.net.LinkProperties");
Method getProxy = linkPropertiesClass.getMethod("getHttpProxy");
Object proxyProperties = getProxy.invoke(linkProperties);
if (proxyProperties == null)
return false;
Class proxyinfo = Class.forName("android.net.ProxyProperties");
Field actualhost = proxyinfo.getDeclaredField("mHost");
actualhost.setAccessible(true);
Object actualhostStr = actualhost.get(proxyProperties);
return actualhostStr != null && actualhostStr.toString().equals(host);
} catch (NoSuchFieldException | IllegalAccessException
| IllegalArgumentException e) {
return false;
} catch (ClassNotFoundException e) {
return false;
} catch (NoSuchMethodException e) {
return false;
} catch (InvocationTargetException e) {
return false;
}
}
}
}
return false;
还有一种方法是用adb
adb shell dumpsys wifi | grep "Proxy settings: STATIC" -A 1
//如果有代理返回代理信息，否则返回为空，结合下面的命令判断是否是当前激活的wifi
adb shell dumpsys netstats | grep "Active interfaces:" -A 1
