Question

Is it possible to disable wireless networking on an Android device using the Android SDK or NDK?

Answer 1

In order to enable / disable the WiFi state, you have to grant the following permission in the application manifest

android.permission.CHANGE_WIFI_STATE

You can then use the WifiManager to set enable/disable the WIFI.

WifiManager wifiManager = (WifiManager)getBaseContext().getSystemService(Context.WIFI_SERVICE);
wifiManager.setWifiEnabled(enabled);

Answer 2

Yes you can disable the wifi programmatically:

1. Retrieve a WifiManager object from Context.getSystemService(Context.WIFI_SERVICE)
2. Set setWifiEnabled to true or false as you wish

Look up for the permission settings. You will probably need to add some in the AndroidManifest.xml
