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;  }
