What is "Input dispatching timed out" and how to solve it ?

Hi,

My app got a lot of ANR with "Input dispatching timed out (Waiting to send non-key event because the touched window has not finished processing certain input events that were delivered to it over 500.0ms ago" at emplacement : com.unity3d.player.UnityPlayerActivity

I don't know what does that mean and how to solve it, or at leat how to investigate and understand this error.

For example here is one of the error my player got :

Thanks if anyone can help me !

We are having the same problem in one of our games. We are using Unity 2018.4.7f1

Any usual suspects for this? Like Admob or certain Monobehaviour methods?

Thanks!

 

same her switched to 2019.3.12 form 2019.2.x and got tons of errors. like this :
Input dispatching timed out (Waiting to send non-key event because the touched window has not finished processing certain input events that were delivered to it over 500.0ms ago. Wait queue length: 23. Wait queue head age: 8335.7ms.)

 

I wonder a lot of people seeing the same issue, and basically when using Unity, and Unity people are trying to tell us that we should do this and that and no idea where is what. I don't see such an issue building a similar game in other engines. Should not Unity engine better handle if they know what is happening. It's definitely not about the game, it's about how the engine handling some implementations.

We have a similar issue with the games built-in Unity engine, and really could not dig much as not getting enough help or where to look at it, compared to any other game we implemented in different engines.

 

Hi,

Thanks for sharing this.
Did you do anything that lowered the number of ANRs, please?

I also see a lot of ANRs that are coming from Android 8.1 (SDK 27)
Google Mobile Ads Unity Plugin v5.3.0
Unity 2017.4.40

Hello there!
Has anyone found a solution or has an update on the above? I recently started to get an alarming rise in ANR as well (they went above the vital threshold for the first time) over the last 2 to 3 weeks, looks like something related to ads.

One suspect I have is the following code:

Code (CSharp):

1.    public void HandleRewardedAdFailedToLoad(object sender, AdErrorEventArgs args)
2.     {
3.         MobileAdsEventExecutor.ExecuteInUpdate(() => {
4.             Logger.Log("coltoads", "HandleRewardedAdFailedToLoad " + args.Message);
5.             Invoke(nameof(RequestAd), automaticRetrySecondsInterval);
6.         });
7.     }
8.  
9.     public void HandleRewardedAdClosed(object sender, EventArgs args)
10.     {
11.         MobileAdsEventExecutor.ExecuteInUpdate(() => {
12.             Logger.Log("coltoads", "HandleRewardedAdClosed ");
13.             rewardedClosedEvent.Invoke();
14.             RequestAd();
15.         });
16.     }
17.  
18.     public void HandleRewardedAdFailedToShow(object sender, AdErrorEventArgs args)
19.     {
20.         MobileAdsEventExecutor.ExecuteInUpdate(() => {
21.             Logger.Log("coltoads", "HandleRewardedAdFailedToShow " + this.name);
22.             Invoke(nameof(RequestAd), automaticRetrySecondsInterval);
23.         });
24.     }

AdMob callbacks are not thread-safe so I instead execute the code in the MobileAdsEventExecutor.ExecuteInUpdate lambda, does anyone else use this or a similar method that might be causing the issue?

I'll submit a new build shortly without that code to see if it reduces the ANR rate

 

Did you have any progress with this?

 

I am uploading the build today, the only other hint I got so far is that in the AdMob Unity plugin, there's a C# 'lock' statement instance here:

https://github.com/googleads/google...gleMobileAds/Common/MobileAdsEventExecutor.cs

which should be compatible with what @Tomas1856 suggested above.

I have now basically removed all the paths to that 'lock' statement by bypassing the MobileAdsEventExecutor GameObject. Fingers crossed.

 

Looking at the code, it only wraps basic C# List code, there is no reason for a dead-lock to occur there.
Also, we're not using GoogleMobileAds directly, but rather via IronSource mediation, so we don't even have that C# code running, yet still get the ANRs.

Let us know if you have any progress.

 

please keep updating the progress, I'm facing the same problem with ANR

 

Below is our ANR rate compared to the category average (puzzle).
It's clear there was a store-wide rise in ANR rates starting on Dec 10th and stoping on Dec 15th.

 

We're experimenting exactly the same rising @doarp has shown, even the very same days.

 

Hi! We see almost the same increase
Unity 2018.4.25f1
Any ideas how to fix?

 

@Galimski Did you update any ads SDK within December 31th update your screenshot shows?

 

Unfortunately, no update so far has fixed the issue on our end. We are now trying to revert changes we made in the previous builds leading up to the increase. We are using AdMob (mediator), UnityAds, Superawesome, Kidoz and Chartboost as ad networks and we saw the increase after we added Chartboost and upgraded AdMob and UnityAds. Is this someone else using the same networks? Maybe sharing the configuration with each other can help us figure this out?

 

No, we didn't

 

We're too. Same ANR rising. Did you find the reasons?

 

We didn't hitherto.

 

Hi everyone
I also face same issue but no find any solution if you have any idea about it please tell me a reason why game has been crashed

 

We are facing the same issue, we are using ads meditation between, admob, unity ads, ironsource, adcolony and inmobi. From many of the stack traces that we analyze we can confirm ads mediation is the culprit (especially iron source). we even publish an update without ads implementation & ads sdks, the ANR's and crashes have significantly reduced since then (actually by whole a lot). Kindly keep this thread updated if you or anyone you know find some sort of solution.

 

The same issue we're facing. Anyone can help? Thank you.

 

Same issue: recent ANR rate spike on Android 8.1 (SDK 27). Using only Unity Ads, nothing else...

 

same here

 

Same problem. 1,8% ANR. Admob + mediation fb/unityads

 

same here

 

I realized that the problem was with ad requests. I was requesting ads at the same time as starting the Google Mobile Ads SDK. you must request ads after the SDK starts and try not to request more than 1 ad per line of code. The Anr rate is decreasing a lot after the last update of my app.

 

Hi . I have the same using Admob ads only (latest version 5.4.0). I am also not requesting ads more then one. Still facing this issue.
Also using the Firebase SDK (Crashlytics,AnalyticsMessaging)

 

Thanks for exposing your case @Franciscotx56. We don't think ours is the same, though. As @sohailciit38 has said, we're not requesting twice or whatnot — it started w/o any update on our side, indeed.

 

Same here problem... We are using Appodeal SDK mediation.

 

I have same result but there is still anr

Unity ads :/

 

We are having the same issue on new version of our game in Unity 2020.3.11f LTS.

On this version we have included Google Native Review Api which relies on Google Play Core libraries and in PlayCoreEventHandler.cs there are 2 "lock" function inside which we can not bypass as we are using the Review Api.

How can we fix this problem so our ANR won't peak ?

PlaycoreEvenHandler.cs (Attached as well)
-------------------------------------
private void HandleEventInternal(Action action)
{
lock (_sharedEventQueue)
{
_sharedEventQueue.Enqueue(action);
}
}

private void Update()
{
lock (_sharedEventQueue)
{
while (_sharedEventQueue.Count > 0)
{
var action = _sharedEventQueue.Dequeue();
_localEventQueue.Enqueue(action);
}
}

// Invoke events outside of the lock because they may take an indeterminate amount of time.
while (_localEventQueue.Count > 0)
{
_localEventQueue.Dequeue().Invoke();
}
}
---------------------------------------------------------------

 

Has anyone found a solution for this?

 

Any Solution .

 

Most likely related to mediation, ad networks, and android resolve/
Make sure you are using the minimal set of SDKs, with all the proper dependencies for ad networks, and that you are performing and android resolve on the final build architecture (64 bit e.g.). This helped us. Especially, when using IronSource mediation, make sure you have zero manual dependencies to ad networks and that you IronSource add the dependencies and do the android resolve. Also be sure you are using the latest versions of everything.

 

Did you find any solution for this? We are having the same and it's affecting ANRs. We are using the latest on IS or one of the latest on ironSource.

 

I have same problem for 2+ year, since google play started showing ANR

 

I've made a sneaky solution that might help. I'll be testing it on our live build over the coming weeks, and will report its effectiveness here. In the meantime, I welcome any suggestions to the idea and the implementation:
https://github.com/lucbloom/unity_anr_supervisor

ANR Supervisor
A system that detects ANRs in the main thread and closes the game before the ANR is reported to Google. It reports the ANR to our own backend, which stores it in a Database for review.

This alleviates the ANR rate reported by Google Analytics. Most ANRs are caused by Ad SDKs (e.g. Google's own AdMob), so there is an option to only enable it during ad views.

Another solution could be to make a list of problematic devices and not show ads on those devices, but that's a project for another time.​

 

But what are the side effects? maybe more people will get angry ... , will it change an app freeze by closing it... ? perhaps the people will vote with less starts ? is this a plausible scenery?

 

What are the results of this solution?

 

It works, technically. The app is closed before the ANR is detected by Google. We have not seen any sign of false-positives. If it hangs for > 2 sec, it's in the AdMob code. Come to think of it, that is what I should have added. Only activate when the stack trace of the blocked thread includes "gms", AdMob code

@Alima-Studios we have the choice between
- 5 second hang + close by Google "This app is not responding" dialog
- auto close
Seeing this is only happening to a small % of users, I wanted to experiment with the 2nd option.

BUT! Seems like Google finally stepped up and we have a very promising update, guys!

https://developers.google.com/admob/android/optimize-initialization
https://developers.google.com/admob/android/rel-notes

I'm going to adopt this version with great joy, in favor of my own experiment.

 

https://github.com/googleads/googleads-mobile-unity/releases/tag/v7.0.2

New Unity AdMob SDK with 21.0.0 support

 

Any update after implementing this fix?
I've updated to Admob 21.0.0, and using UnityAds mediation, but the ANR has not decreased yet.

I just notices that it requires turning ON the flag for optimization from Manifest.

Important: Both the OPTIMIZE_INITIALIZATION and OPTIMIZE_AD_LOADING flags are set to false by default.

I'm planning to try removing the mediation if this fix is not resolving the ANR issue. This issue severely damaging to the discoverability in the Playstore.

 

How is it going? thanks

 

I just released a phased roll-out for few days, so the data is still limited. I can't confirm yet if the occurrences is lower after implementing this "optimized" SDK, but unfortunately this issue is still occurring.

What I did is :
Using Admob 21.0.0 and turning on the Optimization flag.
Still using UnityAds mediation.
Spreading out the Initialization, RewardedAd request and Interstitial for few seconds as suggested by Franciscotx56.

 

FYI: I am not using Admob SDK or any other 3rd party SDK at all and still get a lot of from the same ANR when I enable Unity ADS.

 

I'm doing exactly the same thing. I also downgraded my project to Unity 2021.3.2 which most people say it's safer than newer ones. But I'm still getting the same issue. I noticed that most of problematic devices are Motorola. I own three Motorola devices and for some luck (or not) I could reproduce the issue myself in my Moto E5. Unfortunately it happens so randomly that I couldn't reproduce ever again.

I do not discard the possibility of this issue being caused by Unity Ads. I updated both AdMob and UnityAds before started to get this trouble. I was using Unity Ads 3.7.5 (which is the recommended one) but I had to update to 4.0+ because Play Console now requires some policies that are available only on Unity Ads 4.0+. So it looks like a dead end to me. I'm constantly keeping track of threads like this one to see if anyone manages to find the real cause or any solution.
