DHCP for HTC Android hotspot Configuration

Recently, we have been studying the establishment of mobile phone hotspots. HTC mobile phones are more difficult. First, they cannot modify the SSID, bssid,

I searched on the Internet, there is a blog to solve this problem, please refer to: http://blog.sina.com.cn/s/blog_adc221ac01011mrs.html

Then I found that the HTC mobile phone hotspot was built, but other mobile phones could not connect to it. Later I found that using static IP addresses could solve this problem, but it was too troublesome.

This article describes how to manually configure a local DHCP configuration in the HTC WiFi hotspot program com. HTC. wifirouter to automatically obtain the IP address.

But how can we implement it with code.

After studying for a long time, I only need to dump all the classes unique to HTC. The Code is as follows:

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 blocke.printStackTrace();} catch (IllegalArgumentException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (IllegalAccessException e) {// TODO Auto-generated catch blocke.printStackTrace();}    Log.e(TAG, "dumpHTCWifiFunction2--");    }

The member variable dhcpenable was found. It was a Boolean variable at the beginning, but it was wrong. An error occurred during the setting.

Simply print out its type and change the print statement:

Log. E (TAG, "found API:" + fieldlist [I]. getname () + "type:" + fieldlist [I]. tostring ());

Found API: dhcpenable type: Public int android.net. Wifi. wificonfiguration $ hotspotprofile. dhcpenable

It turns out to be an int-type variable, and it can be estimated that it is set to enable.

The complete code is as follows:

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;}
