Closed Chuckytuh closed 3 years ago

Chuckytuh commented 6 years ago

In this particular application user's can come return to the activity that has the AR Scene multiple times. However, by the third time that a new Session() is created, the following exception is thrown:

E/blg: *~*~*~ Channel {0} was not shutdown properly!!! ~*~*~*
        Make sure to call shutdown()/shutdownNow() and wait until awaitTermination() returns true.

The sceneview is being paused and destroyed pretty much like the sample showcases and it only happens from the third time on 🤔

I've asked our Cloud Anchors group to respond to this as it seems to be within the cloud anchor system.

jrullman commented 5 years ago

We have identified the cause of the crash and will have a fix in an upcoming release.

inio commented 5 years ago

The fix for this didn't make the cut for 1.6 but will be in our next release.

bigant88 commented 5 years ago

I got the same exception. Please fix this early.

I am also seeing this issue with a Pixel 3 XL, ARCore version 1.7.190128146

Even though my app is not crashing, I see the same logs in logcat.

As a part of ongoing efforts to maintain ARCore repositories, I’m closing this issue as stale since it hasn’t had activity in more than 6 months. If this issue is still relevant, please feel free to file a new bug using the latest version of the SDK.
