libc.so unknown crashes in firebase Crashlytics dashboard in my production

[mohamed-ikram]

Hello I have migrated rn-firebase to "@react-native-firebase/app": "^8.4.6", "@react-native-firebase/crashlytics": "^8.3.0"

in firebase Crashlytics dashboard crashes have issues shows libc.so unknown with the help of logs I tried to reproduce the crashes cant able to do that anyone please explain what does it mean or any way to fix the crashes I have received more than 200 crash events for a single day

[mikehardy]

It's some native crash, there are some related reports here and last I know is that @AndrewMorsillo was going to try to get something cooked up with native symbolication so these were more decodable, https://github.com/invertase/react-native-firebase/issues/4253#issuecomment-707895559 - but it's not an easy task and I'm not sure if there is any progress. In the end this isn't a react-native-firebase problem per se, you've got a crash somewhere in your app and it's just that crashlytics isn't giving you enough information to find it because of the way react-native is built and packaged - that's out of our control unfortunately

I see these in my app as well, but I don't have any action to take, I suggest following that issue I linked

[tiggem1993]

@mohamed-ikram Can you share your dependencies list from package.json? I am also facing lots of libc.so crashes and after googling I have found one third party dependency is making these crashes. These crashes are not reproducible under fix number of steps. I have created two build for test with and without those dependency and found My app was not crashing without that dependency.

[tiggem1993]

@mohamed-ikram This might be culprit "smartlook-react-native-wrapper": "^0.37.0". So many peoples are facing libc.so related crash after implementing it. See the below links. https://github.com/smartlook/smartlook-mobile-issue-tracker/issues/28 https://github.com/smartlook/smartlook-mobile-issue-tracker/issues/53

Even I have seen Smartlook team is still trying to fix this issue: IMPORTANT LINK https://github.com/smartlook/smartlook-mobile-issue-tracker/issues/28#issuecomment-732028043

Please cross check with your Firebase Crshlytics logs. Also make a build without smartlook and test it. I am sure it should not crash.

[mohamed-ikram]

thanks @tiggem1993 ill check and let u know

[tiggem1993]

Hi @mohamed-ikram , Have you checked? please let us know.

I have upgraded my "smartlook-react-native-wrapper" from 0.31.0 to 0.39.0 and found now crashes occurring in Android 7 only. So I did research and found Android team said in its Android 7 release that they prevents our apps from dynamically linking against non-NDK libraries, which may cause our app to crash. Same they also prevent our app's third party libraries to linking with non-NDK libraries.

So we are now finding is libc.so belongs from non-NDK library file? If yes then how include in our project to prevent crash.

We also trying to find a method about how to check which dependency is using this libc.so file? And how to fix it.

Please help us. @mikehardy @mohamed-ikram

Did you found other way to build to prevent frequent crashes in Android 7?

[mikehardy]

@kavishmehta spending any time at all troubleshooting when your software is not up to date is incredibly inefficient, I don't even try. Update to current stable on your packages in all cases unless you have specific known incompatibilities then attempt to reproduce

"@react-native-firebase/analytics": "^7.6.9",
"@react-native-firebase/app": "^8.4.7",
"@react-native-firebase/crashlytics": "^8.4.12",
"@react-native-firebase/messaging": "^7.9.2",
"@react-native-firebase/perf": "^7.4.10",

How old are these now? Quite old.

[kavishmehta]

thanks @mikehardy will update the required packages

[cozmoc]

been able to find a solution, for me the issue was mainly caused by the inconsistent behaviour of date.toLocaleDateString function on Android. https://stackoverflow.com/a/51400372 the easiest solution I could find is to replace toLocaleDateString everywhere in the app with a custom made version.

const toLocaleDateString = date => `${date.getDate()}/${date.getMonth() < 9 ? `0${date.getMonth() + 1}` : date.getMonth() + 1}/${date.getFullYear()}`;

[nikhilk1993]

Any updates on this? facing the same error..

[mikehardy]

There will not be updates on a closed issue from nearly a year go based on a comment now with no versions or stack traces specified, no, sorry

If you get a crash in "libc.so" you've got a crash, but it likely has nothing to do with firebase or our crashlytics module. You just have some random crash in your app, I don't believe there is anything this module can do actually.

If you can post a stack trace that has a crash with a stack frame directly in this module, then we have an issue that needs attention here: that's the criteria. If you look at the original crash for instance, RNFetchBlob looks like it blew up. Nothing to do with react-native-firebase...

[badredaha]

The same thing here :/
