User notes

Accidentally enabled WIFI eats battery. It also facilitates tracking. This app helps to reduce this by turning off WIFI.

By default the app only listen to WIFI changes. You need to enable the app (checkbox) to activate the turn off WIFI feature. If want to connect to a new (not whitelisted) network, you need to disable the app, scan or connect to whitelist the SSID/BSSID, then enable the app again. (Otherwise it would just instantly turn off the WIFI.)

The app only cares whether the SSID/BSSID is among the WIFI scan results, so connection errors does not turn off the WIFI.

The whitelist, currently connected networks, available networks are color coded (red, green, and gray respectively).

A notification is shown if the app is enabled.

Architecture overview

It subscribes to android.net.wifi.SCAN_RESULTS, etc receivers, and checks the WIFI connection and WIFI scan result. It never uses another data source (i.e., cell or GPS), and never starts scanning. The only setting change is when it turns the WIFI off.

The build process and repo structure is opinionated: I want to keep the source files and resulting apk minimal. See Makefile

Permissions used

• CHANGE_WIFI_STATE and ACCESS_WIFI_STATE should be obvious
• ACCESS_FINE_LOCATION WIFI scan result usually pinpoints your location, see in the api as well
• WAKE_LOCK not sure if needed, but should not hurt; the service holds it

Pre-release

Please provide an apk for testing the app.

Low priority notification

It would be nice to have an option to have lower priority notification so that it can be grouped with other low priority notifications 😀

[Feature Request] Add delay before switching off WiFi

Whenever I loose the connection for a few seconds even though I'm still in range, WiFi is switched off. So a delay, maybe adjustable, would be nice.

[Feature] Allow adding networks from android saved networks

It'd be nice if the app allowed selecting saved networks that are not in range at the moment.
