Firebase crashlytics not able to read crash reports

Issues filed here should be about bugs in the code in this repository.
If you have a general question, need help debugging, or fall into some

[REQUIRED] Step 2: Describe your environment

• Android Studio version: 3.6.3_
• Firebase Component: crashlytics___ (Database, Firestore, Storage, Functions, etc)
• Component version: 17.0.0_

[REQUIRED] Step 3: Describe the problem

Just integrated firebase crashlytics into our app. Other services, like analytics and remote config are working fine. Invoking a crash from the app doesn't show on the firebase console. After investigation I found that there is an issue with writing/reading the log files.

Steps to reproduce:

--------- beginning of main
--------- beginning of system
--------- beginning of crash

Just integrate the SDK

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

[moetouban]

Any updates on this issue @TKBurner ? it currently prevents us from integrating firebase crashlytics into our app. Is there a workaround for that matter? maybe using an older version for the time being?

[WillCalderwood]

I'm also seeing this stack trace. Android 10, same Firebase version.

[TKBurner]

Thanks. Are you doing any cleanup on app shutdown or relaunch that would delete this file? Are you seeing this on all devices?

[WillCalderwood]

I'm doing no cleanup of files on startup or shutdown. I currently only have 1 test device, but the reason I found the problem is because 3 users have emailed me saying they're experiencing crashes and none of those crashes have been reported. I have had 1 crash reported, so it's obviously working on some devices, but the ratio of crash emails to crash reports would suggest it's not working on more devices that it is working on.

[mrwillis21]

Hey folks - just wanted to chime in here and thank everyone for reporting this! Definitely seems strange. For those of you seeing it, are you able to reproduce it 100% of the time or does it seem to be transient?

[WillCalderwood]

It's 100% of the time on my device. Pixel 3a. Unfortunately all my still working old devices have been adopted by the kids with Family Link accounts that Google wont let me run debug mode on, so I can't test on another device without inducing a meltdown.

Would having an APK help you? Happy to link to one with a forced crash in.

[mrwillis21]

@WillCalderwood appreciate the offer! I think I have a sense of what might be happening here, so any corroborating evidence would be helpful. If you could - please enable debug logging on your device by running adb shell setprop log.tag.FirebaseCrashlytics VERBOSE, start up your app, crash it, then grab the logs from logcat. If you're comfortable posting them here, that's fine, or feel free to send them (and the APK if you'd like) through https://firebase.google.com/support/troubleshooter/contact. Just reference this Github issue, and let them know I requested the information. :)

Thanks again!

[WillCalderwood]

@mrwillis21 Sorry for the slow reply. I seem to have a test crash that's appeared on Crashlytics now. I've been trying to work out what's changed/what's going on. That said, I'm still getting the error. Here are the logcat files.

One file with everything and one with just Firebase. Do you still want the APK after looking at this? If so, I'll send it over shortly.

[mrwillis21]

@WillCalderwood I'll take a look at those files - thanks! And if you're open to sending across the APK, I'm happy to try it out locally.
