HTC Android Hotspot 热点配置 之DHCP

最近在研究手机热点的建立。HTC手机比较坑爹，首先一个，是不能按常规的办法修改 SSID, BSSID,

在网上搜了下，有篇博客把这个问题解决了，请参考：http://blog.sina.com.cn/s/blog_adc221ac01011mrs.html

然后就发现HTC手机热点是建好了，但是其他手机去连它，怎么也连不上，后来发现，使用静态IP能解决这个问题，但太麻烦了。

研究了下通过手动配置HTC的WiFi热点程序 com.htc.WiFiRouter 里面有一个Local DHCP的配置,把它勾上就能自动获取IP。

但要怎么样用代码实现呢这下坑爹了。

研究了半天，还是只有把HTC独有的类给它全部dump出来，代码如下

public void dumpHTCWifiFunction2(){
    	 Log.e(TAG, "dumpHTCWifiFunction2++");
//    	Method[] classMethods = null;
    	Field localField1;

    	Field[] fieldlist;
    	WifiConfiguration apConfig = new WifiConfiguration();
    	try {
      localField1 = WifiConfiguration.class.getDeclaredField("mWifiApProfile");
        localField1.setAccessible(true);

            Object localObject2 = localField1.get(apConfig);

            localField1.setAccessible(false);

            if(localObject2!=null){
            	fieldlist = localObject2.getClass().getDeclaredFields();

            	for (int i = 0;i < fieldlist.length; i++)

                {

                    Log.e(TAG, "found api: "+ fieldlist[i].getName());

                }
            }

    } catch (NoSuchFieldException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
    } catch (IllegalArgumentException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
    } catch (IllegalAccessException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
    }

    	Log.e(TAG, "dumpHTCWifiFunction2--");
    }

发现了 dhcpEnable 这个成员变量，刚开始猜它是boolean变量，但错了，在设置的时候会发生错误。

干脆把它的类型也打印出来吧，打印语句改为：

Log.e(TAG, "found api: "+ fieldlist[i].getName()+" type:"+fieldlist[i].toString());

found api: dhcpEnable type:public int android.net.wifi.WifiConfiguration$HotspotProfile.dhcpEnable

原来它是int型变量,估且猜它是1为enable. 设置之后，果然可以。

完整代码如下：

private boolean setWifiSSIDForHTC(WifiConfiguration apConfig) {
      boolean successed = true;

//	    WifiConfiguration mnetConfig = new WifiConfiguration();
      Field localField1;

                      try {

                          localField1 = WifiConfiguration.class.getDeclaredField("mWifiApProfile");

                          localField1.setAccessible(true);

                          Object localObject2 = localField1.get(apConfig);

                          localField1.setAccessible(false);
                          if(localObject2!=null){

                              Field localField5 = localObject2.getClass().getDeclaredField("SSID");

                              localField5.setAccessible(true);

                              localField5.set(localObject2, apConfig.SSID);// netConfig.SSID);

                              localField5.setAccessible(false);

                              Field localField4 = localObject2.getClass().getDeclaredField("BSSID");

                              localField4.setAccessible(true);

                              localField4.set(localObject2, apConfig.BSSID);//netConfig.BSSID);

                              localField4.setAccessible(false);

                              Field localField6 = localObject2.getClass().getDeclaredField("dhcpEnable");

                                localField6.setAccessible(true);

//                                localField6.set(localObject2, "true");//netConfig.BSSID);
                                localField6.setInt(localObject2, 1);

                                localField6.setAccessible(false);

                          }

                      } catch(Exception e) {

                          e.printStackTrace();

                      }
      return successed;
  }
