How do I turn on and off the Wifi on Android? I would like to turn on the signal every time someone opens the app, and turn it off the moment they close.

You can use the class WifiManager for this, in particular the function setWifiEnabled.
Example (within an Activity):

WifiManager wifi = (WifiManager)this.getSystemService(Context.WIFI_SERVICE)
wifi.setWifiEnabled(true); // Liga o WiFi
if (wifi.isWifiEnabled()) {
    // WiFi está ligado
}

Note that you will need to add some permissions:

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>

In your particular case, I suggest not turning off the Wifi when leaving the app if it was already on when the app opened. In other words: only hang up if you called yourself.

  • Thanks, it worked here.
