电脑在Android的USB绑定模式没有WIFI,编程方式的IP地址 [英] Ip address of PC in USB Tethering mode in Android without WIFI, Programatically
问题描述
我如何编程得到其Android手机连接在USB绑定模式的PC的IP地址,默认网关和端口号,而无需使用WIFI经理?
我使用的网络接口,但它不给我正确的信息,还有没有别的办法?
的(列举<的NetworkInterface> EN = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements()){
NetworkInterface的INTF = en.nextElement();
对于(枚举< InetAddress类> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements()){
InetAddress类InetAddress类= enumIpAddr.nextElement();
如果(!inetAddress.isLoopbackAddress()){
。地址+ = inetAddress.getHostAddress()的toString();
}
}
}
确定这里是一轮关于我达到了,从通过网络接口接收的地址,我在致辞中删除最后一个部分,如192.168.1.40解决方案我取出40,并通过循环遍历从192.168.1.0出发,找出实际连接的端口。该片段是低于
的(IDX = 0; IDX< = 255; IDX ++)
{
尝试
{
T [IDX] =新主题(新的Runnable(){
公共无效的run(){
海峡= IPpart +。 + IDX;
插座=新的Socket(STR,PORT);
IP = socket.getInetAddress()的toString()。
网关= socket.getLocalAddress()的toString()。
}
});
T [IDX] .setName(IPclass);
T [IDX]。开始();
如果(IP!=)
{
closeThread();
打破;
}
}赶上(例外前){}
}
How can I programatically get the Ip address, default gateway and port number of the PC to which the android phone is connected in USB Tethering mode, without using WIFI Manager?
I used network interfaces, but it doesnt give me the correct information, is there any other way?
for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {
NetworkInterface intf = en.nextElement();
for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {
InetAddress inetAddress = enumIpAddr.nextElement();
if (!inetAddress.isLoopbackAddress()) {
address += inetAddress.getHostAddress().toString() ;
}
}
}
Ok here is the round about solution that I reached, from the address received through the network interface, I remove the last section in the address, like 192.168.1.40, i remove 40 and iterate through a loop starting from 192.168.1.0 and find out the port which actually connects. The snippet is below
for(idx=0; idx <=255; idx++)
{
try
{
t[idx] = new Thread(new Runnable() {
public void run() {
str = IPpart + "." + idx;
socket = new Socket(str, PORT);
IP = socket.getInetAddress().toString();
Gateway = socket.getLocalAddress().toString();
}
});
t[idx].setName("IPclass");
t[idx].start();
if(IP != "")
{
closeThread();
break;
}
}catch(Exception ex){ }
}
