First you need to communicate with the router, I mean, for eg. in your webbrowser if you write 192.168.x.x (router login webpage) you can access to your webconfig right? And to turn On/Off your wifi you must go to the right place right? Its like this ..
In your android app you must in first place know how to connect with router ip, if you can do this almost 60% of path is done, next you need to know how you turn On/off , and how do you know ? Almost of the router have one ssh login or telnet login, and almost of the routers have commands to open ports for example, you need to check you router manual and see what is the command to turn On/Off you wifi with terminal (telnet or ssh).

Thank you reply!
router use method protocol GET to config. EX: turn of wifi: http://192.168.0.254/userRpm/WlanNetworkRpm.htm?ssid1=Ngoan®ion=105&channel=15&mode=4&chanWidth=1&broadcast=2&brlssid=&brlbssid=&keytype=1&wepindex=1&authtype=1&keytext=&Save=Save
Router support remote login + no-ip.com and i can config it by 3G of smartphone. But this problem is authentication required of router when run this example

The authentication ?
There is a house where to known people they have a secret ring ...
what do you need to enter in the house ? if you have no key ?
you need to POST the secret ring..
First step again :
You need to authenticate yourself, when you put in the browser 192.168.0.254 what appear ? a windows to insert yours creds, that windows is make from anything right ?
otherwise you have the key ? what do you need to enter in the house? The place where you insert the key (that i dont know how to say in english lol )
if you have the creds you need to check if your router can be access by TELNET or SSH !!
or you must find the protocol that is used in the loggin of the router , for exemple wireshark is good for that job

I doubt that statement as stated is possible.
If a router was running then one must either use a wired or wireless connection to access it.
You probably think that your cell phone is going to connect wireless to the router. But then that means that the router must have a wireless management API. (And to use that you learn about IP, TCP, HTTP at a minimum.)
Now if and only if you can access the admin via the wireless access then it should be possible to turn the router off.
But once the router is off you cannot connect to it - by any means. So it would not be possible to turn it back on. Same thing if you mean disabling the wireless connectivity.

So research how http authentication works.

You should learn to use Google for general research questions, as you will need to use it a lot. In the meantime start with the Java Tutorials[^].

Hello,
Firstly - good on you for wanting to learn Java!
With regards to tutorials - there are multiple resources available - one set of tutorials I found extremely helpful were "The Java Tutorials." It is quite helpful for a beginner, giving aid and direction. You can access the tutorial here: http://docs.oracle.com/javase/tutorial/java/index.html[^]

Take a look at the Java Tutorials[^].
You just need to add something of the form:
public static void main(String args[])
{
}
