URGENT - Many crashes since ARCore 1.16.0

[agGitHub]

SPECIFIC ISSUE ENCOUNTERED

ARCore 1.16.0 has been recently released.

The corresponding 'Google Play Services for AR' app has been released on March 16th, 2020 and March 19th, 2020.

I note in my Google Vitals dashboard that the number of crashes increased dramatically since these two dates. A first small increase on March 16th, a second huge increase on March 19th.

I note this increase on both my free app and paid app, even if none of them was updated around these dates. I initially thought that it could be linked to the fact that my free and paid apps are compiled against ARCore 1.0 ; I submitted an update of my free app compiled with ARCore 1.16.0 but it changed nothing to this problem of crashes.

VERSIONS USED

• Android Studio: versions in production around March 16th were compiled with a previous version of Android Studio ; new version of my free app compiled with Android Studio 3.6.1 => probably not a problem of Android Studio version
• ARCore SDK for Android: both 1.0 and 1.16.0
• O/S : Android 8, 8.1, 9, 10. The Android version crash distribution is the same as my Android version installation distribution => this crash does not seem linked to the Android version.
• Device manufacturer: many and perhaps all of them (or almost)
• Models: many and perhaps all of them (or almost) ; it seems that the crashes are not systematic on each type of model ; for example, I see crashes on Samsung S10+ models but I am unable to get a crash on my S10+. The device model crash distribution seems to be close to my Android version installation distribution => this crash does not seem linked to the device model.

STEPS TO REPRODUCE THE ISSUE

Not able to reproduce this bug. Seems to be a random bug since the update of 'Google Play Services for AR' app released on March 16th, 2020 and March 19th, 2020.

WORKAROUNDS (IF ANY)

No workaround at the moment.

ADDITIONAL COMMENTS

My crash rate has been multiplied by 6, from 1% to 6% by this problem.
6% of my sessions crashing, it is really way too much...

As the rating of the app didn't decrease, and as I have no comments saying that the app doesn't work, I have got the feeling that the app crashes on 6% of sessions, but do not crash systematically on a defined device. It may crash on a device and then works fine once the app relaunched by the user. I think that a user will have 6 crashes if he/she launches the app 100 times.

Thanks a lot for your help on this urgent matter.

The device model crash distribution seems to be close to my Android version installation distribution

Can you please indicate which Android o/s versions your app is experiencing issues on?

We see this issue in our vitals data, too. Slightly different PC but all in all the same problem I would say!

All our crashes are on Android 9 and on Samsung Galaxy A6 (a6lte) devices if that helps.

We have encounter this issue too. The details is here : #1025. In our side, the device varies. These are the devices which have been tested and encounter the crash :

• Samsung Galaxy A6
• Google Pixel 2016
• Samsung Galaxy Note 8 (SM-N950F)
• Samsung Galaxy S9+ (SM-G965F)
• Samsung Galaxy S8 (SM-G950F)

We have tried upgrading ARCore to v1.16.0 but the crash still occurs. The only resolution to avoid the crash is to downgrade Google Play Services for AR to v15.

[idstein]

We also see exactly this issue. On our S10 devices we resolved it via explicit uninstallation of Google Play Services for AR and issued a new installation via Google Play.

However, that is an unacceptable resolution for real users.

[balarayen]

previous has many tracking issues and this version is crashing a lot :(

Issue solved with last release of ARCore app on Google Play. Closed.
