I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

zwu52 · 2020-10-09T14:05:58Z

Previously FIID broadcast handling was done and main thread and caused lots of ANR. It was fixed and rolled out earlier this year (not sure which release was in. Likely >= 20.1.3). IIRC, you updated the app to 20.2.4 but still sees many ANR crashes. Do you have any insights on the demographics of the SDK versions these crashes are on?

PratyeshSingh · 2020-10-21T08:38:12Z

I was also getting the same ANR. So i'm sharing my finding here with you all guys to reduce this ANR.

Memory Leak can be one reason for emitting this com.google.firebase.iid.firebaseinstanceidreceiver ANR.
So you can verify on Android profiler for memory leak, If memory leak issue is fixed then this ANR automatically come DOWN.

Hope this help to all you guys.

PratyeshSingh · 2020-11-24T03:56:34Z

Hi @zwu52 @google-oss-bot ,
Here is one use case in which we can reproduce this ANR.

I have many app in my phone which receive daily 200+ push-notification each-app every-day. So i putted my device offline for 2-3days, later then came to online and then started getting notification more than 1000+ PNs (older & pending PN).

Log Details:-
_#00 pc 0000000000071160 /system/lib64/libc.so (__epoll_pwait+8)
#00 pc 0000000000014200 /system/lib64/libutils.so (android::Looper::pollInner(int)+144)
#00 pc 00000000000140cc /system/lib64/libutils.so (android::Looper::pollOnce(int, int*, int*, void**)+60)
#00 pc 0000000000127264 /system/lib64/libandroid_runtime.so (android::android_os_MessageQueue_nativePollOnce(_JNIEnv*, jobject*, long, int)+44)
at android.os.MessageQueue.nativePollOnce (MessageQueue.java)
at android.os.MessageQueue.next (MessageQueue.java:326)
at android.os.Looper.loop (Looper.java:190)
at android.app.ActivityThread.main (ActivityThread.java:7212)
at java.lang.reflect.Method.invoke (Method.java)
at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run (RuntimeInit.java:499)
at com.android.internal.os.ZygoteInit.main (ZygoteInit.java:942)

Device details:-

So in my opinion, if we receive many PN at same time this ANR surely occur.

@google-oss-bot @zwu52 kindly look on this use case. while receiving 500+ push-notifications is their a way to properly schedule these many push notification to prevent this happening?

Jack29913 · 2021-01-15T16:06:34Z

I am also seeing this issue.
Especially after migrating from 20.1.7 to 20.3.0 and changing targetSDKVersion to 30.
This is critical as my app passed ANR threshold because of this.
And no, it has nothing to do with memory leak.

zwu52 · 2021-01-19T20:54:59Z

@Jack29913
I am sure you have traced through #594 and wasn't able to fixed your issue. Do you mind verifying or pasting (event better) your stack trace here. ANR issues had different causes and does yours also consist these com.crashlytics.android.core.CrashlyticsCore calls?

@rlazo Rodrigo,
This particular ANR looks like to be a triggered in a crashlytics call path? can we route in crashlytics folks to take a look

zwu52 · 2021-01-20T23:22:13Z

Jack,
Processes seem to be waiting on GMS. Can you confirm if your play service is up2date and what is the version number?

Jack29913 · 2021-01-21T08:19:59Z

@zwu52
Are you asking these?
classpath 'com.google.gms:google-services:4.3.4'

'com.google.android.gms:play-services-base:17.5.0'
'com.google.firebase:firebase-messaging:21.0.1'

zjamshidi · 2021-02-03T07:37:20Z

I'm facing the same issue

classpath 'com.google.gms:google-services:4.3.3'
classpath 'com.google.firebase:firebase-crashlytics-gradle:2.2.1'
...
implementation 'com.google.firebase:firebase-messaging:21.0.0'

JeremyR34 · 2021-02-05T09:19:59Z

Same issue here
implementation platform('com.google.firebase:firebase-bom:26.3.0')

zwu52 · 2021-02-05T23:38:33Z

@Jack29913 Jack,
Thanks for the info and patience. I can't seem to reproduce the ANR with the corresponding config. Here is what we can decipher from the attached stack scripts.

For 1st one on Android 5.0 - Android 7.1, main shows the last trace to be on some shared preference operations. Couple possible reasons that this can happen. 1. Shared preference is dead locked somehow. 2. Shared preference is ok and the stack just trace shows the tail of your processes. This could be caused by slow disk write typically on older devices where storage is less than 1G.

For 2nd one on Android 9 - Android 10, the UI thread seems to be just chilling out and not blocked.

I'd like to triage this to our Crashlytics folks to further diagnose if possible.

@zjamshidi @JeremyR34, the ANR could be caused by various reasons, please check out the #594 to see if it helps. Otherwise, we'll update in this thread.

mrwillis21 · 2021-02-08T21:45:19Z

Hi everyone - just wanted to let you know that the com.crashlytics... SDK is deprecated, and that it should be replaced with com.google.firebase.crashlytics.

zjamshidi · 2021-02-09T04:52:48Z

@zwu52 You are true. ANR could be caused by other reasons. I made some changes in my code and will see if the resolve the issue.

Jack29913 · 2021-02-09T14:45:46Z

I am using firebase.crashlytics already. And seeing massive numbers anr's coming from every android versions except 11: 5.0, 5.1, 6.0, 7.0, 7.1, 8.0, 8.1, 9 and 10.
This is my top 4 ANR's.

nzayatz14 · 2021-02-09T21:17:18Z

I also started receiving these ANRs when updating com.google.firebase:firebase-messaging from 20.1.7 to 21.0.1.

Also, I have seen them happen on Android 11 devices

RodolfoGS · 2021-02-16T02:40:40Z

@google-oss-bot ¯_(ツ)_/¯

joelfernandes19 · 2021-02-23T07:25:46Z

We have high volume of DAUs and we're seeing this ANR more often. Using com.google.firebase:firebase-messaging version 20.1.7.

Any updates on this?

--

@nzayatz14 @zjamshidi after updating to 21.0.0 (or above) do you notice any drop in ANRs?

nzayatz14 · 2021-02-23T12:20:24Z

@joelfernandes19 I actually had a huge increase in ANRs when upgrading to 21.0.1. I recently reverted back to 20.1.7 and the ANRs went away

zjamshidi · 2021-03-03T04:19:27Z

I fixed the ANRS. They weren't related to Firebase SDK and the source was how we access the DB.

RodolfoGS · 2021-03-03T13:40:06Z

@zjamshidi Could you share what kind of changes you made?, maybe I or anyone have the same issue. Thanks,

zjamshidi · 2021-03-05T06:10:48Z

The ANR was:
Broadcast of Intent { act=com.google.android.c2dm.intent.RECEIVE flg=0x1000010 pkg=xxxx cmp=xxxx/com.google.firebase.iid.FirebaseInstanceIdReceiver (has extras) }

So I was suspicious of Firebase SDK but when I checked the stack trace I noticed we wait for reading data from DB in the application onCreate method.

  at xxxx.XApp.onCreate (XApp.java:118)

I moved this part from the application onCreate to the first activity after the splash and it's fixed now.

In general, what I learned is we should not do or wait for a task that may take longer than 5 seconds (like reading data from db) on the main thread. Very simple!

@zjamshidi Got it, I'll check that in my app, thanks a lot!

Jack29913 · 2021-03-08T08:40:52Z

This is not the case at all. This is the stacktrace of main thread. Also there is no DB access in our app.
Firebase changed something in their code, we didn't get so many ANR's before.

any luck so far?

Jack29913 · 2021-04-12T08:21:15Z

nope. they probably think if no one talks about it, it will magically solve itself.

mtrezza · 2021-04-15T12:39:17Z

Same issue on com.google.firebase:firebase-messaging:21.0.0, but there is a 21.1.0 release which may fix it:

Migrated internal handling of new token callbacks and notification actions from Firebase Instance ID to Firebase Cloud Messaging.

Added functionality to generate FCM tokens from FirebaseMessaging.getToken, while continuing to call through to Firebase Instance ID if it is present. This will allow Firebase Cloud Messaging to remove its dependency on Firebase Instance ID in the future.

It actually removes the dependency on FirebaseInstanceId which is always part of these crash logs.
You'd need to get the token from FirebaseMessaging instead of FirebaseInstanceId, see here.

Did anyone try, using BoM 27.0.0?

wangirving · 2021-04-28T01:05:22Z

I have been following this issue for a long time. I found that after I started using App Bundle recently, the anr is much less.I didn't do anything else.

zwu52 · 2021-04-28T17:59:48Z

To organize the thread bit since there is a mix of ANR here, some are resolved some aren't yet resolved. Below are two seemingly ongoing issue:

OP @RodolfoGS on FM 20.2.4: ANRing in the FirebaseApp init ContentProvider (before FM initialization). The original stack traces shows dependencies on deprecated com. crashlytics. @RodolfoGS please let us know if your ANRs were resolved after updating the dependecies.

@Jack29913 on FM 20.3.0 stack traces. It looks like FM threads aren't blocked or locked. It might be app taking too long to process the broadcast? I am seeing there is a change to optimize FM internal broadcast flows that is code ready and queued up for upcoming release. I'll update the thread and please monitor and feedback @Jack29913

prcaen · 2021-05-19T20:24:17Z

@mtrezza have you try BOM 27.0.0 or above finally?
Does it fix?
Thanks

prcaen · 2021-05-21T07:34:01Z

I updated BOM to version 28.0.1, and still have the ANR :(.

kiranInmobi · 2021-08-03T08:29:01Z

Any update on this? Even we are facing lot many ANR

zwu52 · 2021-08-03T15:33:23Z

Hi @prcaen , @kiranInmobi and rest of friends who are experiencing ANR,

I am inclining to close this thread because it's becoming a soup of ANR by different root cause as far as I could tell and hard to read and follow for folks coming later.

Please read above & see if you could find your crashes/fixes above. If not, please fill a separate bug attaching a full bug report.

As you might have noticed from above, ANR could be caused by many factors including low RAM/disk, fcm related, non-fcm related issues. Majority of the stack traces provided don't contain enough information for us to diagnose forward. So if a comprehensive bug report or logcat could be provided that would super helpful and greatly appreciated.

Cheers 🍺
