Fingerprint gesture block not working since Android Pie

[Raju Purohit]

Hi developer,
I have updated to Android Pie and noticed that fingerprint gesture block is not working anymore as Android Pie has gotten stricter with background access to sensors.
Is there any work around? Can you fix it either with root or non root solution?
Thank you

[Henrik "The Developer" Lindqvist]

The fingerprint scanner is not an "sensor", and Automate is running the "foreground", so the sensor throttling shouldn't be the issue anyway.

Android is buggy and has problems restarting accessibility services, try rebooting the device.

[Raju Purohit]

Yes you're right about foreground thing. And I've tried restarting the device but didn't help. I never had any issue with accessibility service.

I checked with one app (https://play.google.com/store/apps/details?id=com.ztc1997.fingerprint2sleep) and its description also says the app won't work in Pie. Can you or anyone confirm if it is working in your Android Pie?

Thank you

You may also check this XDA post (https://forum.xda-developers.com/oneplus-5t/themes/magisk-fingerprint-swipe-left-home-t3880790) where the developer says third party fingerprint gestures are not detected since Pie. He has developed magisk module just for this.

Maybe the OnePlus fingerprint hardware doesn't support standard AndroidAPI, some (older?) Samsung devices doesn't either.

[Raju Purohit]

Maybe but weird since it worked fine in Oreo on both Oxygen OS and Omni ROM. But doesn't work on Pie versions of Oxygen OS nor on crDroid which I'm using presently.

I also checked with my friend's Mi A2 running on stock Android Pie and this fingerprint gesture block doesn't work on that too.

So I've come to believe Pie version is the reason.

Sadly i don't have an Android 9 with a fingerprint scanner to test on yet.

Ensure no other app (e.g. Google Now maybe) or the system (e.g. system Settings, System, Gestures) are using the gestures.

[Raju Purohit]

Thanks for your suggestion. I don't have Google Now installed and I tried disabling system setting for swipe down gesture for notification shade, but still the block didn't work.

Anyways, I'll wait till you can test it out. I'll investigate myself too to find if anyone had such issue and found any solution.
Thanks

Just to chime in - i switched from a Nexus 6P on Oreo to an LG G7 One running Android Pie (not rooted) and the fingerprint gestures don't seem to be working for me either anymore. i've dug into the System Settings and there don't appear to be any conflicts. i've given Automate permissions for everything except superuser, and i've disabled Google Assistant and made Automate the handler for its gestures. Seems like the specs or permissions must have changed between Oreo and Pie? Not your fault i know.

i would love if you have any time to investigate and figure out a fix! i've built a little mini-suite of music tools to skip/replay/like/log/fast-forward/record audio using only fingerprint gestures. i love Automate dearly, it's turned my phone's fingerprint thing from the most useless feature into a thing i use a hundred times a day.

[Henrik "The Developer" Lindqvist]

Try disabling any other app with accessibility service access, since that's needed for the fingerprint gestures,  and the system gesture navigation feature.

[webm...@blueseaphilanthropy.org]

Gave that a try:
- Disabled all gestures in System
- Made sure Automate is the only app enabled for Accessibility
- Disabled Google, Google Assistant, the Android Accessibility system app and a few others just to see if it would have any effect

- Also rebooted the phone after each change

Haven't had any luck so far. The G7 One runs stock Android, so it in theory shouldn't have any weird proprietary things around to mess things up. Below are a few screenshots.

I don't know much about Android development, but I noticed that FingerprintManager class was deprecated in API level 28 (Pie) and was replaced by BiometricPrompt. Can this be causing conflict in using FingerprintGestureController class?

I'm sorry if this sounds stupid, as I've already mentioned I don't know much about Android development.

[Henrik "The Developer" Lindqvist]

Unlikely. It's likely a device issue since i haven't got any other reports, or maybe an Android bug but i cant find any public bug reports.

I have the same issue on Xiaomi Mi Mix 3

[Henrik "The Developer" Lindqvist]

I'll add some logging to help with debugging.

Same issue with update to android pie on huawei p20 lite. Fingerprint gestures don't work anymore.

[Fran T]

FWIW, it's working fine for me on a Pixel 2 XL running Pie.

[w.m.chr...@gmail.com]

Samsung Note 9 doing finger print gestures either...

[Solomon M]

Same issue pixel 2, stopped working after update. Would love to have this back working. Thanks

[Henrik "The Developer" Lindqvist]

Please enable the "Debug logging" option in setting, run the flow, then post what the block is logging.
