Stopping in to ask if anyone has had success with this in the new Pixels. I just set it up on my P6P, and everything seemed good until I tested it with the screen off, at which point...nothing.

I was kind of hoping it wasn't too dissimilar to the P5, now I'm hoping someone may have some insight, or can at least tell me I'm boned lol. Either way, thanks for everything Chainfire

I simply love this app. Can it deal with notifications from "work profile" apps? These are selected by my employer but it would be great to see their notifications highlighted by Holey Light.

@Chainfire love this app, tested it out on Note 10+ yesterday but have yet to put into service as i have yet to migrate fully over..

I do have one suggestion in a bid to save battery.. is it possible to control how long the notification blinks? for example, set it to blink every hour for a period of 10min.. so that it doesnt trigger wakelocks constantly, yet we dont really miss notifications fully..

I must be blind, can't see the telegram link. Using on Pixel 6 Pro and want to know if there is a way to fully disable AOD or not. Thanks!I'm not familiar with your device & you aren't blind - The Telegram Link isn't there now & There isn't an "invite" link in his group - But if you like I could add you to it?

Hello and sorry to disturb you.

The UnholeyLight option seem to doesn't work on my Pixel 4a with CalyxOS (Android 12)...

Have you ever had this problem?
Thanks for your help !

You might be better off asking Chainfire on his Telegram Group - There's a link to it on the Play Store description.
I don't know how often - If he checks here?

Using this on a Pixel 4a5g and after adjusting the location of the "LED" quite a bit, it's working very well.

Test version for Android 13 / One UI 5

Unfortunately, fixes for Android 13 (and particularly the required store updates) have resulted in breaking changes for the renderer. I fully expect this to look wrong on older Samsungs and Pixels :(

If so, let me know on Telegram: https://t.me/joinchat/I8HshhIHzwrJalUJ

    Holey Light     is a LED emulation app. It animates the edges of the camera cut-out (AKA punch-hole) as replacement for the sadly missing LED on many modern devices.

    Additionally, it provides a notification display for when the screen is "off", replacing - or working in conjunction with - the Always-On Display feature. As this display is not around the camera hole, it is aptly named the Unholey Light.

    Supports all Samsung devices with in-screen camera hole, and several Google Pixels.

    Features
    • Emulates notification LED
    • Four different display modes: Swirl, Blink, Pie, Unholey Light
    • Configurable animation size, position, and speed
    • Customizable color for each notification channel
    • Selects initial notification color by analyzing dominant color of app icon
    • Displays during screen "off", sub-1% battery use per hour in Unholey Light mode
    • Separate configuration modes for different power and screen states
    • Ability to mark notifications as seen based on various triggers
    • Respects Do-Not-Disturb and AOD schedules
    • Can hide AOD completely, partially, and/or keep the clock visible
    • Additional AOD Helper package for further battery usage reduction
    All teh details and all teh sauce!

    It's all on GitHub!

    Download

    You can grab it from Google Play.

    Feedback

    You can feedback here. Or in the GitHub issue tracker. Or talk to me on Telegram. I guarantee no response or fix.

    The workings of the app are quite intricate, so describe what is happening in minute detail.

    TODO

    You can find the TODO list in the issue tracker.

    Enjoy!
    Or not.

    v0.40 is here

    So, it was quite a journey to get to this point, and I am sad to report I am not fully satisfied with the results so far. But I have more than exhausted the time I have available for side projects, and I need to focus on work for a while now. There are further gains to be had, I'm sure, possibly someone else will figure it out while I'm doing other things :)

    The past weekend I've dedicated entirely to investigating power and CPU use, how AOD functions, etc. A lot has been done on the main code-base to reduce its usage (such as replacing live animations with pre-rendered sprite sheets), but on that front we have reached the point of diminishing returns. There's not much more to be improved in that part of the code. It was a lengthy merry-go-round, as fixing things in one place would break things in another. Here's some technical mumbo jumbo for all y'all to enjoy.

    First, there was the move to accessibility services. Should have been using those from the start, but I decided against it because (a) I botched up my first attempt, (b) it is frowned upon by Google (but apparently still grudgingly accepted for now), and (c) it's just unclean. On the other hand, Google has nerfed all the other ways to overlay (in favor of their upcoming "bubbles" contraption), so there's little choice left. This allowed for simplification of part of the codes and getting rid of the fake lockscreen, in favor of piggybacking on AOD. Unfortunately that itself has not brought all the improvements I had hoped. We still need to use the CPU quite a bit, and though we now have the advantage of the screen being in a lower power state and other apps being more restricted from running (both improving battery life), I've still clocked it at 3.5% (worst-case, down from 5.5%) per hour. Obviously this is only when you actually have notifications, otherwise it doesn't any battery at all.

    It is my understanding right now (and this may in time prove to only be partially correct, or even completely incorrect), that AOD periodically offloads an image (the background, notifications, clockface without hands) to the display, and a separate process (sidekick? outside of Android? dedicated hardware?) updates the screen with the smaller changes (such as the clock hands). This allows the main CPU to be fully asleep while you still see a clock with a moving second hand on screen, using sub-1%/hour battery power. AOSP has supporting code for this, so it's possible. Additionally, I've experimented with hiding AOD by drawing black on top of it - and the clock's hands remain visible while everything else disappears. Interesting stuff, for sure (stay tuned for more tales of interest).

    Overlays apparently are not part of this 'saved' image (I'm sure I saw a reference to how this is done somewhere in AOSP source, but I can't find it anymore, good job bookmarking that), so as the screen goes into its lowest power mode, they disappear. To counter this, we need to keep updating the screen (I had a work-around for this at some point, but it needs further investigation still). Some of you noticed the swirl didn't "time out" as the blinker did, that is because the swirl updates at a higher FPS. That high FPS keeps an internal lock deep in Android active, preventing the lowest power mode from being enabled. I've spent quite(!) some time trying to get to that lock, but to no avail. The only alternative is updating the view layout regularly, which also pokes that lock (after going through a long path of many other functions): this keeps the app's CPU usage down, but I later discovered this triggers high CPU usage in system_server, and so it was a net loss. There have been several instances of me saving 10-20% in one place just to have it pop up somewhere else, just because we don't have a direct path to the code inside Android we actually want to trigger. In the end, I've upped the FPS of the slower animations to 5-10, which seems to keep the screen happy (at least for me), as long as I don't have a better solution.

    I've also done some experiments with a shell runner (code that needs to be started through adb with a PC, or through root if you have it), which had some interesting results. Though inconvenient, it does give us access to a number of permissions we can use to manipulate power states. Unfortunately, for most of it there still doesn't appear to be a way to actually do so - no path to the correct Android internals. If I have the time it any point in the future, I'll dig a bit deeper into that, but my opinion right now is that it'll probably require proper root and changing (overlaying) some system files and/or settings.

    I've decompiled and analyzed a lot of Samdroid's packages, but so far haven't found the holey grail :) (See what I did there? Now I need to make a new app with that name...)

    PS: This one will be going up on Play ASAP
    PPS: For those reading on GitHub, the sauce is up, but I have not updated all the info yet, and that may not happen today
    PPPS: I saw some translations come by, please update them to the texts from this version and re-post, thanks. GitHub pull request would be even better, but I understand if that's not your cup of tea
    PPPPS: For the devs: there's some interesting stuff and comments in the code if you look closely

    As always with these releases, it was probably working fine this afternoon and I botched something major up just before releasing this update, so come at me with your bugs and observations :)

    Most significant changes (this includes things already in v0.26)
    - Screen off + battery functionality enabled
    - Migration from fake lockscreen to AOD-base
    - Migration from application to accessibility overlay (Google frowns on this, though)
    - Any notification can now be used for LED. The ones that don't ask for LED show up under Colors as black by default.
    - Lottie renderer has been replaced by a sprite-sheet based rendered (up to 5x CPU reduction)
    - Battery saving animations added (up to 3x CPU reduction), blinking and pie-chart (decided based on full or on-tap AOD)
    - Several leaks and crashes have been fixed (and undoubtedly new ones created)

    Good news everyone! I have it all running smoothly now. The code need some cleanup, dead code removal, fixing up some bad test code into "meh" production code, some installation helpers, etc, but I have the basics all working as I want them.

    Going to run it overnight to see what the drain is... release hopefully tomorrow.

    Now that I've figured how AOD works, I mostly finished up the AOD hiding (even without the addon package, but the latter is still better on battery if there are no notifications), now I just need to clean up the UI (oh no!) and provide ample in-app instructions and guidance, then I can release that to Play and continue on the other features (such as schedule/dnd, etc).

    This cleaning up is my least favorite part of devving. It already works fine for my own uses now.
