Question ANR in crashlytics console: android.os.MessageQueue.nativePollOnce

Hello, i've been having some headcache with this ANR that seems pretty common in the project that i'm working for:

Project setup:
Unity 2020.3.34f1
Google Admob 6.2 ( with Facebook Mediation and UnityAds Mediation )
Facebook SDK v11
Firebase 8.10.1

In the past weeks i've been trying another set of versions for the plugins that i'm using and the issue is still happening, but i don't know how common is this, anyone here have experienced something similar?

It happends at game lauch.

Hi, did you find some answer to this issue? I got similar ANR and no clue on how to solve it.

 

It seems caused by Admob SDK or mediation. There is another thread discussing this same issue.
https://forum.unity.com/threads/wha...-out-and-how-to-solve-it.833515/#post-8333103

 

From my experienced at work, I was reduced RAM and CPU usage. Then ANR goes down like crazy.

RAM = Use Memory Profiler and try to reduce overall RAM usage to 1GB~2GB.
CPU = Find a way to optimize scripts to have at least 20+ FPS on average mobile phone.

 

Can you describe more clearly how you did it? Like using sprite atlas or something.
What is the way to optimize scripts?

 

CPU = Use Profiler to track, if any CPU spike pop you need to fix it.
RAM = Same as I said on post # 4.

 

Having the same ANRs. Unity 2020.1.17, I'm not using admob, my ad mediation is AppLovin. No FB SDK either. Firebase can't even detect those ANRs, I can only see them in Google Play console and there is empty stacktrace so I can't even understand when/where it happens. So disappointing ;(

 

Avoid using Awake() too much use Start() instead. Doing this my ANR's dropped from 0.7% to 0.19%

Use Awake() in just one script per scene.

Me myself was facing the increasing ANR's issue and I got them reduced from 0.7% to 0.19% just by replacing Awake() by Start()

 

Is there anyone find the solution of this anr?

 

Still struggling We even updated Unity to 2022.1.22 (was 2020) but nothing changed.

 

Our game is also seeing ANRs which we are trying to fix. Ours looks like this:

Input dispatching timed out (7d9aadb com.####.###/com.###.Activity (server) is not responding. Waited 5002ms for FocusEvent(hasFocus=true))

  

With a similar stack to yours:

[URL='https://docs.bugsnag.com/build-integrations/']__kernel_rt_sigreturn

<unknown>

android::Looper::pollInner

android::Looper::pollOnce

<unknown>

<unknown>

com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run

com.android.internal.os.ZygoteInit.main

 [/URL]

Can anyone confirm that a FocusEvent being sent from Android will cause OnApplicationPause to be called in Unity? If so, I can at least bookend each OnApplicationPause call with a pair if Bugsnag breadcrumbs, and any call with a missing [End] breadcrumb would be a likely culprit

 

is there a fix for this problem?

 

Any one have Solution this error or Any idea how to solve this ANR

 

SIGSEGV

Getting this error as crash in crashlytics. Can anyone help to solve this ?

 

I am alos facing this issue any solution please??

i am using latest
Firebase: Version 11.6.0

Is there any relation with the Unity version? we have 2 games practically with the same code but on unity 2021.3 we get half of the ANR's than with unityu 2022.3

 

you mean latest 2022.3.16 version?, that one hasn't this issue ?

 

@juan_homa Yes it is because of the Unity version. you can try the lastest version.

 

@juan_homa Give Release2022.3.16f1 a try. It can help mitigate ANRs, although it might not eliminate them entirely.

 

Thanks !!!

 

did this help you?
