Android: Send data only by WIFI

问题

I have a service that runs in background and send data to a server, I want to send this data only by wifi and not another way (gprs or else) is that possible? and if it is, how can I achieve that? if you have sample codes or links that would be great. thank you.

回答1:

final ConnectivityManager connMgr = (ConnectivityManager)
 this.getSystemService(Context.CONNECTIVITY_SERVICE);

final android.net.NetworkInfo wifi =
 connMgr.getNetworkInfo(ConnectivityManager.TYPE_WIFI);

The NetworkInfo structure should have the connectivity state of the Wifi Subsystem. Look at the documentation:

http://developer.android.com/reference/android/net/NetworkInfo.html

Use the isConnected method to see if wifi is connected. Easy Peasy!
