Flutterfire: 🐛 [firebase_crashlytics] Failed to retrieve settings from https://firebase-settings.crashlytics.com

[sulaysumaria]

Bug report

I added firebase_crashlytics to a new flutter app and ran it. In logs, it simply logs this error and my crashes are not reported to firebase console:

E/FirebaseCrashlytics(23176): Failed to retrieve settings from https://firebase-settings.crashlytics.com/spi/v2/platforms/android/gmp/1:639321596024:android:2e8626b6d04d73c1aecd8d/settings

I hit this URL manually and it returns a 403 error. Not sure if it is expected or not.

Steps to reproduce

Steps to reproduce the behavior:

1. Create a new flutter app.
2. Create a new firebase app.
3. Add firebase_crashlytics plugin to flutter.
4. Configure the android build.gradle files.
5. Run the app.

Expected behavior

The crashes should be logged in firebase upon next launch of app.

Additional context

I followed the tutorial here to add crashlytics: https://firebase.flutter.dev/docs/overview/

May be it's a 24 hours patience game or try the solution below:

Few changes made were:

• Add implementation 'com.google.firebase:firebase-analytics:17.5.0' implementation 'com.google.firebase:firebase-crashlytics:17.2.1' to app level gradle
• Add classpath 'com.google.firebase:firebase-crashlytics-gradle:2.3.0' to android level gradle.
• Add firebase_analytics to pubspec.yaml, this is just a fluke.
• Rebuild the app code and do a force crash in the app. And after waiting for a minute or two, upon refreshing Crashlytics Dashboard I see...

[alien190]

May be it's a 24 hours patience game or try the solution below:

Few changes made were:

* Add `implementation 'com.google.firebase:firebase-analytics:17.5.0' implementation 'com.google.firebase:firebase-crashlytics:17.2.1'` to app level gradle

* Add `classpath 'com.google.firebase:firebase-crashlytics-gradle:2.3.0'` to android level gradle.

* Add `firebase_analytics` to pubspec.yaml, this is just a fluke.

* Rebuild the app code and do a force crash in the app. And after waiting for a minute or two, upon refreshing Crashlytics Dashboard I see...

I had a try to implement this solution, but it didn't work for me, unfortunately.
On the overview page of the Firebase project, I can see some past statistics from Crashlytics, but the Crushlytics console is not still available.

Thanks that work for me, but I need to call FirebaseCrashlytics.instance.crash();
to make Crushlytics console available.
I'm getting a Crushlytics alert in the console about migrate to the newer sdk

[ycv005]

Also, add apply plugin: 'com.google.firebase.crashlytics' to the bottom of the build.gradle of app level.

I made sure to follow all the instructions yet I am also experiencing this issue. The solution above did not work.

(i try on emulator with google play, i was blocked since 1 week)
What step do ? For me :

• follow answer above
• uninstall your app
• flutter clean
• Install again your app
• Crash your app with FirebaseCrashlytics.instance.crash();
• Then restart your app.

Crashs are sent when app open again. Your firebase console will be unlocked :) .

A new plugin version was rolled out yesterday, https://pub.dev/packages/firebase_crashlytics/changelog.
Please upgrade and try again to see if it works.
Thanks.

[darshankawar]

Similar to https://github.com/FirebaseExtended/flutterfire/issues/3676

[dan-leech]

For me it works, but with a new app created in Project Settings.
But it still does not for the old one.

What's interesting that the new store crash report to SQLite:

But the old one not:

All that I change is applicationId. The old one is com.mobile.k***y and the new one is com.mobile.k***y.dev

[xJon]

The error disappeared today on its own.
I still didn't manage to get to the dashboard, until I used an emulator with Google Services.

There are still a few issues that I faced. Maybe that is something firebase has to look at.

• Crashes are not visible in real time. It took around half hour to show up on console.
• When navigated to crashlytics from sidemenu, it shows the initial screen. But once I navigated to Project settings, and then to Crashlytics, it works fine.
• Refreshing the crashlytics page goes to infinite loader.

I agree, I got infinite loader on firebase crashlytics/analytics. Crashlytics is not realtime, it's weird....

[jakubosiak]

After 5 days of trying to initialize crashlytics it finally started to work. I put google-services plugin below dependencies in android/app/build.gradle but it might be just a coincidence.

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'com.google.firebase:firebase-analytics:17.5.0'
    implementation 'com.google.firebase:firebase-crashlytics:17.2.1'
}

apply plugin: 'com.google.gms.google-services'
apply plugin: 'com.google.firebase.crashlytics'

Remember to flutter clean -> flutter run if you want to try if this solution works for you.

I can't get this to work properly either. We use 2 different flavors. When running it locally it works for one flavor but it fails with the "Failed to retrieve settings..."-error for the other flavor. I already tried completely deleting the Firebase-project and using a new one but it still fails.

It does pick up the correct google-services.json because the project ID in the URL is correct. Also, the "Performance" tab already says "We detected that you've added the Firebase Performance Monitoring SDK" on the newly created project, so the Firebase integration in general seems to work.

I didn't see any additional errors with "adb logcat" either.

[joanofdart]

Not only is this issue quite a hassle but when it actually goes past this... then there's another problem with firestore security rules.
Did I miss a config or something?

[aldychris]

It's working on me after update to new version

firebase_core: 0.5.0+1
firebase_crashlytics: ^0.2.1+1`

[HCfebrian]

It's working on me after update to new version

firebase_core: 0.5.0+1
firebase_crashlytics: ^0.2.1+1`

still not work for me. I hope they will fix this in near future

[Ehesp]

We're aware of this, looking to get a fix up asap.

Same error for me.

Thanks. It's working. But, you forget to add plugin firebase_core in pubspec.yaml.

[HCfebrian]

work for me out of nowhere. I think if we sure everything is in the right place, we just have to wait 16-24 hours so that crashlytic dashboard becomes enabled.

I followed the official docs to upgrade/install crashlytics:

https://firebase.flutter.dev/docs/installation/android
https://firebase.flutter.dev/docs/core/usage
https://firebase.flutter.dev/docs/crashlytics/usage

I have also waited more than 24 hours on several projects to see if the Crashlytics console would work, but it didn't work

[EArminjon]

Make sure to add this :

await Firebase.initializeApp();
await FirebaseCrashlytics.instance.setCrashlyticsCollectionEnabled(true);

[msangals]

@EArminjon i also initialized the app in a FutureBuilder and i waited to be instantiated before executing the test crash.

This line of code is not really necessary because by default collection is enabled.
await FirebaseCrashlytics.instance.setCrashlyticsCollectionEnabled(true);

I was finally able to make it work.

There are still a few issues that I faced. Maybe that is something firebase has to look at.

* Crashes are not visible in real time. It took around half hour to show up on console.

* When navigated to crashlytics from sidemenu, it shows the initial screen. But once I navigated to Project settings, and then to Crashlytics, it works fine.

* Refreshing the crashlytics page goes to infinite loader.

This solution avoid the "Failed to retrieve settings from ..." error, but Crashlytics still not connected.

@roger357 this solution also for me didn't work

I finally got it to work by strictly following the flutterfire instructions, and adding the dependencies to app/build.gradle:

dependencies {
implementation 'com.google.firebase: firebase-analytics: 17.6.0'
implementation 'com.google.firebase: firebase-crashlytics: 17.2.2'
}

and the most important thing for me: move at the end of the file:

apply plugin: 'com.google.firebase.crashlytics'

(before the google-services plugin)

i tried everything, none of them worked.

[anotherglitchinthematrix]

I observed the issue is only present in the android emulator, on the iOS platform, iOS integration and testing on the iphone emulator worked perfectly. Then I deployed the android application to the closed-beta track in the playstore and crashed the app in the real device environment, after a short waiting, logs appeared correctly without any trouble. Running the release version of the application through flutter run --release on a real android device may also help.

[kaciula]

I am also experiencing this issue. Using the latest version of everything. I've tried every suggestion from this issue. I still get "Failed to retrieve settings..."

[sbkrishnan2506]

Hi,

I am also getting this error,

[dackers86]

Initial PR added, works consistently through local testing. Please follow the link and follow the steps through the preview documentation.

Any and feedback welcome

[roger357]

Hello and thank you @dackers86 .

I Followed your guideline.

"Failed to retrieve settings ..." message is out, but crashlytics console no detect crashes. Crash was forced with FirebaseCrashlytics.instance.crash();

[erkanmaras]

its worked for me.

[dackers86]

Hi @roger357.

Can you confirm which version of firebase_core you are using?

[roger357]

Hi @roger357.

Can you confirm which version of firebase_core you are using?

Hi @dackers86.

I'm using this firebase_core: ^0.5.0+1

[dackers86]

Thanks.

Could you try firebase_core: ^0.5.0.

[samin-fs]

@dackers86 I have the same problem and I'm using firebase_crashlytics: "^0.2.1+1". would you please help to fix it?

[dackers86]

@roger357 @samin-fs When working through the above docs i'd make sure to do the following....

When using the emulator. Make sure to uninstall the app from the device before rebuilding.

flutter clean && flutter run - only on the initial changes.

Then 'flutter' to re-run the app with the expected crashes.

Apologies if this isn't comprehensive, it took a while to produce initial consistent installations.

Any additional feedback is welcome

[roger357]

Hello @dackers86,

I'm trying with the follow configuration

pubspec.yml

  firebase_core: ^0.5.0

  firebase_auth: ^0.18.1+2

  firebase_analytics: ^6.0.2

  firebase_crashlytics: "^0.2.1+1"

    dependencies {
        // Other dependencies
        classpath 'com.google.gms:google-services:4.3.3'  // Google Services plugin
        classpath 'com.google.firebase:firebase-crashlytics-gradle:2.3.0'

apply plugin: 'com.google.gms.google-services'  // Google Services plugin
apply plugin: 'com.google.firebase.crashlytics'

Initial error message is out and Crashlytics console connects successfully.
Thank you very much.

[manafire]

I finally managed to get this working after shutting down my emulator and following the instructions from @roger357 and @dackers86. Thank you!

Note that this contradicts what's written in the official docs that contain no mention of the BOM and specifically say to remove firebase dependencies from android/app/build.gradle as the firebase SDK reworked plugins _should_ automatically manage them. These inconsistencies sure are confusing. :/

Update:
Adding the BOM and dependencies ended up causing more problems for me, so I disabled them, restarted the emulator and ran it again successfully. Maybe it was the initial emulator restart and moving the 'apply plugin' lines to the bottom that resolved it for me. Hard to say.

My configuration based on this link is not working unforunately.
I've also tried adding firebase_analytics: ^6.0.2 but that didn't worked either.
Let me know if you have any idea how to fix that. Maybe waiting 24 hours would be enough for it to start working?

My configuration:

@snowb1shop @samin-fs

I've been attempting to recreate this morning. Does the issue still exist, I've noticed this morning that the app is initialising even without manually causing a crash?

[snowb1shop]

It started to work, thank you!

[Nico04]

I've tried almost all solution provided here, my config still doens't work.

[Valentin-Seehausen]

Still not working with

  firebase_analytics: "^6.0.1"
  firebase_crashlytics: "^0.2.1"

[dackers86]

@Nico04 @Valentin-Seehausen

Would it be possible to create a test app with flutter create testApp.

This works consistently for new apps, i'm wondering it could be some other configuration?

I've tried that, but it also failed for me 😔

[Valentin-Seehausen]

After creating a new project in firebase and adding configs from https://firebase.google.com/docs/crashlytics/get-started?hl=en&authuser=0&platform=android it worked. Don't know if this is an satisfying solution.

[samin-fs]

@dackers86 i noticed that this problem only happens on the emulator and it's working fine on a real device, thank you.

It looks like on Android they have migrated the crash uploading mechanism to JobScheduler and it schedules automatically to 1 second after the crash. The thing is JobScheduler has no guarantees, you might schedule it to run after one second but the system will instead opt for it to run 15 or even 30 minutes later. I was able to see this in some of my own logs:

Scheduled for 1000ms later:

10-20 15:02:41.651 13633 13728 D TransportRuntime.JobInfoScheduler: Scheduling upload for context TransportContext(cct, HIGHEST, MSRodHRwczovL2NyYXNobHl0aWNzcmVwb3J0cy1wYS5nb29nbGVhcGlzLmNvbS92MS9maXJlbG9nL2xlZ2FjeS9iYXRjaGxvZ1xBSXphU3lCcnBTWVQ0RkZMMDlyZUhKaTZIOUZZZGVpU25VVE92Mk0=) with jobId=-354078233 in 1000ms(Backend next call timestamp 1602031421011). Attempt 1

Scheduled for 488293ms later:

Attempt 1

In the end I was able to see the crashes in my dashboard around 5 minutes after all of this, because the first attempt above was uploaded successfully. I mostly followed @dackers86 guide, except the BOM dependencies. The key points for me were:

• Re-opening the app after forcing the crash(I suggest just tapping the app's icon to open it directly without flutter run)
• Checking the timestamps in logcat to make sure there is no JobScheduler delays and to confirm the upload has finished(this is discussed in the comment I linked above).
• Create a button in your settings menu that only shows in debug builds that can mock a crash(and calls FirebaseCrashlytics.instance.crash).

I suggest the last point about the button because it is written in the iOS/Android documentation. I have a feeling running flutter run consecutively might be causing issues but I can't confirm this it's just a hunch. There's a lot of factors in play here.

I should probably also add that in the iOS documentation it tells you to create a button, start the app in XCode an then stop the app and re-open it directly without XCode. This has something to do with XCode's debugger interfering with Crashlytics(I have no idea if this applies to flutter run too). It also specifically tells you to change your Debug Information Format to 'DWARF with dSYM File'.
