Android 2.2 wifi热点API

Question

我需要在Android 2.2(Froyo)中创建一个API调用来创建一个Wifi热点(如Tethering和Portable Hotspot设置项中所示).

Answer 1

你可以打电话

private boolean setWifiApEnabled(WifiConfiguration wifiConfig, boolean enabled);

使用反射:)

在WifiManager使用反射来获取WifiManager声明的方法之后,查找此方法名称setWifiApEnabled并通过该WifiManager对象调用它

这些API标记为@hide,因此目前您无法直接使用它们,但它们出现在WifiManager的AIDL上,因此可以访问它们!

一个例子可以是:

WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
Method[] wmMethods = wifi.getClass().getDeclaredMethods();
for(Method method: wmMethods){
  if(method.getName().equals("setWifiApEnabled")){
    WifiConfiguration netConfig = new WifiConfiguration();
    netConfig.SSID = "\"PROVAAP\"";
    netConfig.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);
    netConfig.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
    netConfig.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
    netConfig.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);    netConfig.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
    netConfig.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
    netConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
    netConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);  

    try {
      method.invoke(wifi, netConfig,true);
    } catch (IllegalArgumentException e) {
      e.printStackTrace();
    } catch (IllegalAccessException e) {
      e.printStackTrace();
    } catch (InvocationTargetException e) {
      e.printStackTrace();
    }
  }
}

它工作但我不能用我自己的配置更改当前配置,并获得当前的活动AP的WifiConfiguration驱动我为空配置.为什么？
