Thanks for reporting! To help us diagnose this issue, please answer some questions. How often does this occur? Does this only occur on that device model? What version of ObjectBox is used? What version of Android is used?

See the comment in #865 for potential solutions. As the file is on an SD card this might be a case of file corruption.

@whatshappen Thanks! Does the app use multiple processes by any chance?

I have also encountered this issue. Please fix it as soon as possible. Xiaomi 9 is normal, Xiaomi 10 is not normal, and Xiaomi 11 is normal

Copy the database file from the phone that does not report an error to the phone that reports an error, and it can be used normally

[greenrobot-team]

@360060316 Is it possible that the database file is corrupted due to a file system issue? This would explain the error message.

In this case the only option is to catch the above exception, delete the database files and then try to open a new BoxStore.
