Apr 30, 2024 06:11AM

DataStore Component used: androidx.datastore for Android DataStore Version used: 1.1.0 Devices/Android versions reproduced on: Seems not connected to any specific device/Android version as we see it on many different ones on all Android versions.

After updating androidx.datastore from 1.0.0 to 1.1.0 we started to see a lot of the following crashes.

The crashes happen on app startup when we try read from the datastore early in the app startup process. We see a lot of them in the wild. Happened to us locally few times as well, but it's very rare and unpredictable which makes it hard to debug.
Among other calls we use runBlocking to read from the datastore in one place
Our app is single process and we only create the datastore once
We use single process datastore (the code didn't change after updating the lib)

RxDataMigration and RxSharedPreferencesMigration.

Add a wrapper for the RxDataMigration interface so that people can define migrations using RxJava

Relnote: """Added support for migrations written using RxJava with the RxDataMigration interface. The RxDataMigration interface is like the DataMigration interface, except using reactivex.Single's instead of suspend functions. You can implement this interface to define a custom migration.
This change also adds support for SharedPreferencesMigrationBuilder which allows easier construction of SharedPreferencesMigrations from java.

Downgrading from 1.1.1 to 1.0.0 has seemingly resolved the issue for us.

mk...@opera.com <mk...@opera.com> #11Aug 19, 2024 06:54PM

Downgrading is not an option for us as we need multiplatform support.

dc...@openai.com <dc...@openai.com> #12Sep 23, 2024 10:58PM

We are seeing a pretty high volume of this - would be great if DataStore had more graceful handling out of the box, or had a pluggable way to customize it (like with the ReplaceFileCorruptionHandler).

Right now, there doesn't seem to be a straightforward way to change the error handling here, without adding an abstraction above the DataStore itself.

ja...@gmail.com <ja...@gmail.com> #13Oct 21, 2024 10:30AM

I'm not sure why the above error is happening. It seems to be expecting the file to be created first and then queried.

Is there a timing issue?

Downgrading to 1.0.0 appears to have fixed this for us

du...@gmail.com <du...@gmail.com> #15Nov 14, 2024 05:46AM

I got the same issue with version 1.1.1. We have to use 1.1.1 to support Kotlin Multiplatform. Is there any update for this critical issue?

zh...@google.com <zh...@google.com> #16Dec 11, 2024 08:43PM

Reassigned to zh...@google.com.

Sorry for the delay of responding to this issue, as we've seen similar issues in the other bugs and followed up there. This is hard for us to debug as it seems to be a race condition and we cannot easily reproduce it and understand the root cause. Please help us by providing more details (device populations, API levels, or anything you discover as relevant to the bug distribution) from your observation of its occurrence! Also a sample app to reproduce would be great if possible.

In the meantime, I'll try to do some more investigation with the given information. Thanks for your patience.

ps...@google.com <ps...@google.com> #17Dec 12, 2024 09:48AM

It does not seem to be limited to a specific API, I see logs on API 10 to 15.

These are the errors I see on Crashlytics on a Pixel 8 Pro (unfortunately I have not been able to reproduce locally):

I've also been seeing this since updating from 1.0.0 (problem exists in both 1.1.0 and 1.1.1) and so I had to downgrade to 1.0.0 to avoid these crashes.

Has anyone tried: https://developer.android.com/topic/libraries/architecture/datastore?hl=en#handle-file-corruption ? Does it help?

UPDATE: no it doesn't help

having the same issue. Seeing that there is no solution yet, as a temporary test fix, we're considering making a dummy DataStore call immediately at the app startup and catching the exception

Also, had the same issue using it in the compose multiplatform project with datastore library of version "1.1.1"
