How to enable/disable WiFi from an application?

Question

I want to enable/disable wifi from my Android application. How can I do that?

Answer 1

To enable/disable wifi from an app in Android Q (Android 10) use Settings Panel:

val panelIntent = Intent(Settings.Panel.ACTION_INTERNET_CONNECTIVITY)
startActivityForResult(panelIntent, 0)

On previous versions of Android this should work (appropriate permissions should be added to AndroidManifest file, see answers above):

(context?.getSystemService(Context.WIFI_SERVICE) as? WifiManager)?.apply { isWifiEnabled = true /*or false*/ }

Resulting code might look something like this:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
    val panelIntent = Intent(Settings.Panel.ACTION_INTERNET_CONNECTIVITY)
    startActivityForResult(panelIntent, 0)
} else {
    (context?.getSystemService(Context.WIFI_SERVICE) as? WifiManager)?.apply { isWifiEnabled = true /*or false*/ }
}

Where context is a reference to android.content.Context object.
