ANRs due to JobScheduler from Network calls

[Brijwel]

We are also facing ANRs related to JobScheduler used by firebase, we also found some traces pointing to Network calls from com.google.android.datatransport.runtime.scheduling.jobscheduling.Uploader, will this also be fixed as part of the next update?

Relevant trace:

Update: Only occurring in Android 14, after targeting to API 34, and 100% Background.

Hi @Brijwel, thank you for reaching out. It looks like this issue is related to Android changes in JobScheduler, similar to #6147. As mentioned in the description,

com.google.android.datatransport/transport-runtime library is using JobScheduler which is not recommended now as mentioned in android documentation: https://developer.android.com/about/versions/14/behavior-changes-14

Our engineers are already working on this along with other improvements for API level 34 (android 14). Pardon me, but we don't have a definite timeline yet. However, it should be rolled out across all Firebase Android SDKs soon. We hope for your understanding.

To streamline the updates, you can follow on the issue #6147. With that, I'll be closing this issue now. Thanks.
