To test whether this idea was feasible, we investigated the following questions: To test whether this idea was feasible, we investigated the following questions:

On Android versions 9 and earlier (API level <= 28), an app can use the `WifiManager` API to request a connection to a network that's not currently in range. On Android versions 9 and earlier (API level <= 28), an app can use the `WifiManager` API to request a connection to a network that's not currently in range.
If the network later comes into range, the device will connect to it even if the screen is off at the time (tested on the Moto E6 Play and Honor 8A). If the network later comes into range, the device will connect to it even if the screen is off at the time (tested on the Moto E6 Play and Honor 8A).

If not, there's a `CONNECTION_STATE_CHANGE` broadcast about 10 to 15 seconds after the connection attempt that may indicate that the attempt has timed out.

On Android versions 9 and earlier (API level <= 28) the behaviour depends on whether another network with internet access is available. On Android versions 9 and earlier (API level <= 28) the behaviour depends on whether another network with internet access is available.
