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; }
