Native crashes on Android 12

NickFitton commented 2 years ago

Summary

I am seeing crashes on the Google Play Console for the following devices:

Google Pixel 6 Pro
Google Pixel 6
Google Pixel 5
Google Pixel 4a
Google Pixel 3a

All of these crashes are on android 12. I do not have one of these devices to test and provide a sample app, but I suspect a standard npx react-native init Repro could reproduce this on an android device.

Versions

SoLoader: 0.10.1
React native: 0.65.1
Android: 12

Crash header

java.io.FileNotFoundException
com.facebook.soloader.FileLocker.<init>

Other Notes

I cannot reproduce this on an android emulator. We have found that if the user re-installs the app the error can magically resolve.

Found this this error occurs when a user restores a back up from a device to an android 12 device. Re-installing solves the issue. SoLoader isn't the issue, just the first library to start poking files!

@NickFitton, thanks for reporting.

a user restores a back up from a device to an android 12 device

can you describe what is this action? is this a migration from old device to new Android 12 device?

NickFitton commented 2 years ago

Hey! Exactly right, a user of an android device can restore existing data from a previous phone via google, we've found that this can cause what seems to be permission issues. The error seemed to be caused by SoLoader as it's the first lib in our app to touch files.
