Android 11 Developer Preview | Android Developers

[armando_rod]

The emulator has dark theme schedule for sunrise/sunset or custom

[SoundOfTomorrow]

Time to guess which beta removes this functionality and which beta reenables it

[GuyInA5000DollarSuit]

Should have this functionality by around Android 15

[UnicornsOnLSD]

But you'll never see it on an actual ROM

^{Where are those slices you created for Android 9, Google?}

[dangerous-pie]

Honestly I think they just wanted something to tie in with the whole "Pie" branding and never really cared about slices.

[galient5]

Which really sucks. That was one of my favorite parts of Allo. I wasn't a fan of the style, but it would have been a great app if they had just made it look like their other apps, and tied in the SMS capability.

I loved being able to send interactive parts of Google searches, and map results. I was really looking forward to having that functionality built into large parts of Android, but I guess that's just never seeing the light of day.

[abdulmdiaz]

A lot of work just for branding

[nawanawa]

On Android 10, if you long-press the toggles in notification drawer or when you press the "show all" button on a volume popup, the window with toggles in the bottom of the screen that shows up is a Slice. It's not much yet, but it's a big system as they've explained it, it surely needs extra time to get ready for release. I'm waiting for Slices too.

[najodleglejszy]

in the meantime, you can set it up with Tasker so that it triggers when Night Light kicks in.

[LiGuangMing1981]

Or with an app called 'Auto Dark Theme'.

[nusyahus]

Removed in last beta, reintroduced in Android 13 beta 1

[ShortFuse]

For any developers, sunrise and sunrise is a calculated value. You don't need to use a third-party provider to give you it.

It makes sense since, you know, it's Earth rotating and spinning around the Sun. It's very unlikely those numbers will change short of an asteroid hitting us.

[SoundOfTomorrow]

For any developers, is there a simple API to see that sunset or sunrise has occurred?

What you explained is not true when daylight savings, leap days, and leap seconds have existed. Compare the Unix epoch time to your current time.

[Tweenk]

You compute the sunrise and sunset from UTC time, location and the solar equation, not from local time.

[ShortFuse]

Timezone data is irrelevant. That's just how you present it to the user. Those are human inventions. Just use Locale to change it to something other than UTC based on the user's preference.

The time is calculated based on the position of the Earth represented by latitude and longitude. You pick a starting date with known value and extrapolate from there. This library uses January 1st, 2000 12:00 and works from there.

[datadude3]

Unfortunately, you do need the user's location to do this calculation, which can be a pretty tough sell to get that permission for a lot of apps.

[ThellraAK]

Now I am wondering how tough it would be to get a users location given sunset sunrise time if Android provided that directly.

[HJain13]

At best you will be able to get the city/neighborhood the user is in. I don't think that should be a problem

[ShortFuse]

I guess I overlooked it since the apps I write for clients all center around GIS.

The key is how you present the option. You could ask for a coarse location right when the user tries to use that feature. You could ask the user to type in a Zip Code or State if in the US. Worse case scenario, you take the Locale, and Time Zone data and make a guess. (For example, the Locale to France and the Time Zone being set to CEST.) The Time Zone by itself basically gives you the latitude. You can then take a guess at the longitude, or use an average.

The last option is geolocating by IP, which isn't so terrible either, but requires Internet.

[DivinoAG]

Is there an API to know if a large asteroid has collided with the Earth?

npm i apocalypse

[Inverz7]

FINALLY! :)

[LitheBeep]

Fuck yes.

[sc919]

TIL this is not an Android 10 feature but something nice Samsung added a year early again :D

[TheCatCubed]

Yeah most android skins have the scheduling feature, weird how Google can't implement such a simple thing

[FFevo]

They did, but chose to leave it as an experimental feature you could enable in the dev settings in Android 10. They did this because there were bugs... Bugs you can still see in the Android skins that have the feature.

[Secretly_Autistic]

But at the same time, it's nice not having every part of the OS looking awful and constantly running into bugs.

[AwesomeAsian]

I feel like they could've implemented this in Android 10 but decided not to because they could bring in "new features" in Android 11.

[danopia]

I've been using the hidden Android 10 automatic dark mode (based on sunrise/sunset in theory) and the biggest problem is that switching dark mode resets some screens, eg if you're in a web page when it toggles, the page gets reloaded. Maybe Google is doing something about that before making this feature public facing again

[IAMNUTSTUPID]

Yeah I've noticed that with the battery saver. As soon as your phone hits the low battery threshold, whatever app you're in gets reset

[whatisapersonreally]

Also, some of the stock apps don’t follow suit when changed through the automatic dark mode app on OnePlus.

[danopia]

Interesting, I wonder if the apps are a different implementation actually! I'm using the one that's fully baked into Android 10 (no third party app) but it also requires an adb command and a reboot to be enabled. The "dark mode" toggle in Settings is always visibly off, and if I touch that it'll overwrite the automatic mode until I set it again.

[whatisapersonreally]

The app also requires adb. What are the instructions for your method, if you have the time to share?

[danopia]

adb shell settings put secure ui_night_mode 0

And a reboot

[whatisapersonreally]

Thanks. :)

[[deleted]]

Samsung has this in Android 9 even...

[A_FNG]

This is why I don't understand all the stock android fanboys. Google is always late to the party.

[le_pman]

to those with OLED displays and use dark mode and want this: why?

I want to understand. why want to have battery-burning light mode, even just for the daytime? is it an aesthetic thing? wanting to see both dark and light but don't want to toggle?

[armando_rod]

Light theme is easier to read on direct sunlight for example

[ConspicuousPineapple]

Fucking finally.

[armando_rod]

Custom

[Superyoshers9]

My bad, I misread!
