I want to write a program that wants to restrict location updates when the device is in the same wifi network. How would I go about doing that? How do I check if the device is in the same wifi network as earlier?
WifiManager.getConnectionInfo() will give you information about current Wifi network.

How does the auto wifi connect algorithm work on the Android phone? For ex: when I go home, it auto-connects to my home network. When I step into Starbucks, it automatically connects to the Starbucks network. I assume there is a "background service" running on the phone at all times. Is this true?
If so, does this service constantly check the GPS location and then try to simply connect to the local network that was last inside that GPS coordinate?
Or, does the service automatically try to find any local network and simply connect to the first one that it is able to connect to?
Or, does it automatically connect to the most frequently connected network? Does auto wifi take into account the # of times it has connected to each network?
Thank you.
How to get wifi configured networks with wifi turned off in android?
In case this is not possible, Can I turn on wifi but disable the automatic connection to known networks?
After a long search on the net I found that this is not possible :(
I want to give restrict the usage of apps whenever device is in range of my wifi network. and at time my application will start automatically and it should always running within my wifi range, no one can able to disable or close/kill the app only app admin can do this. App will check the wireless networks available in range, and connect to network as soon as it is in range. person will not be able to switch off the wifi or connect to any other network. When device is in range of my wifi, apps will be restricted and only allowed app can be used. suppose we can restrict camera use in my wifi range and camera usage will become unrestricted when device is out of my wifi range. When device is out of my wifi range, person can use their device without any restriction. it is same like sonicwall or firewall can do in internet explorer in windows. we can only use some allowed pages in internet while sonicwall or firewall is on.
What you are looking for is not possible in Android. Apps have very limited permissions and they cannot restrict the behaviour of other apps AT ALL! Here you will get some idea of how to connect to Wifi SSID. But what u ask for is like a device administrator and it is NOT possible.
Not true! It is posable to restrict apps to WIFI only just install the free app Onovo https://play.google.com/store/apps/details?id=com.onavo.android.onavoid
Should my Android phone automatically select wi-fi if available, if not then go to the next data service etc. If I use
connectivity.setNetworkPreference(ConnectivityManager.TYPE_WIFI);
will that ensure the same result or confine it to using wi-fi only.
Yes. By default android chooses WiFi network and if WiFi network is not available then it switches to mobile carrier network. To implement switch form WiFi to mobile network you can follow my answer over here: How to handle WiFi to Mobile network switch programatically?
If the Device is connected to a WIFI network will Android use that because it has 1. priority.
And you will almost always prefer using WIFI to your network operations. So you dont really have to worry about this.
I could see on my different devices (all HTC I have to say), under Android 2.1 and 2.2: when both 3G and Wifi are both enabled and available, the system switches down the 3G to prefer the Wi-fi.
The documentation says "When active, all data traffic will use this connection by default. " Whichever you set as your network preference, that will be made the default connection. The system default must be Wifi itself.
Does anyone knows if the wifi networks for android phones are based on Access Point Names (APN) ? I ask because in my android application I plan to overwrite some fields in all APN's to disable cellular network, but I still want to have available the wifi for the user
AFAIK, WiFi is independent from APN settings, i.e., if you mess with the APN settings WiFi will still work (cf. the APNdroid application).
