HTC Android Hotspot 熱點配置 之DHCP

最近在研究手機熱點的建立。HTC手機比較坑爹，首先一個，是不能按常規的辦法修改 SSID, BSSID,

在網上搜了下，有篇部落格把這個問題解決了，請參考：http://blog.sina.com.cn/s/blog_adc221ac01011mrs.html

 

然後就發現HTC手機熱點是建好了，但是其他手機去連它，怎麼也連不上，後來發現，使用靜態IP能解決這個問題，但太麻煩了。

研究了下通過手動設定HTC的WiFi熱點程式 com.htc.WiFiRouter 裡面有一個Local DHCP的配置,把它勾上就能自動擷取IP。

但要怎麼樣用代碼實現呢這下坑爹了。

 

研究了半天，還是只有把HTC專屬的類給它全部dump出來，代碼如下

 

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--");    }

發現了 dhcpEnable 這個成員變數，剛開始猜它是boolean變數，但錯了，在設定的時候會發生錯誤。

乾脆把它的類型也列印出來吧，列印語句改為：

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

 

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

原來它是int型變數,估且猜它是1為enable. 設定之後，果然可以。

 

完整代碼如下：

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;  }
