Describe the problem

After releasing a new version ni production with up to date Firebase libraries we have many new crashes (Google Play developer console & Firebase Crashlytics).

Steps to reproduce:

Up-to-date libraries versions. Notes

• it seems to happen only on Android 7 & 8 devices.
• it may be related to this: https://github.com/firebase/firebase-android-sdk/pull/1234

@JeremyR34 Really sorry for the inconvenience. I have raised the priority of this issue with my team and should have some update by early next week. I understand that catching the OverlappingFileLockException is a quick fix. However, we need to evaluate what the impact of catching this exception will be on the Firebase Installation service.

Thanks for sharing the timelines with us. I will keep that in mind when addressing this issue.

I saw a fix in firebase-installations:16.3.1 that try to catch the error but actually failed? the OverlappingFileLockException not match IOException or Error. https://github.com/firebase/firebase-android-sdk/pull/1521/commits/c3d4b09c11fdda469d34796ad701a5e47ad1426c
