io.objectbox.exception.FileCorruptException: Could not get from cursor (corrupted) (error code -30796)

In my Pre-launch report details I see continuously crashes on Android 8.1 phones. I cannot reproduce it on a Emulator with SDK 27. Stacktrace error (see for log details below): io.objectbox.exception.FileCorruptException: Could not get from cursor (corrupted) (error code -30796)

Is this a issue with pre-launch testing or might this occur on real devices as well? After searching I found multiple issues with Android 8.1. Any clue?

I'm using a read-only box from a fragment (write box is in a remote service).

• ObjectBox version 2.8.0 (but also on 2.7.1)
• Reproducibility: always on Android 8.1 devices for pre-launch report
• Device: e.g. Motorola moto e5 play and Nokia Nokia 1
• OS: Android 8.1

Code
Initialization done in MainActivity class after being connected to Service (remote process). The method initMainActivity is called.

protected void initMainActivity() {
        if (!mInitMainActivity) {
            JepsterManager jepsterManager = (JepsterManager) getApplication();
            jepsterManager.initReadOnlyBox();
            //Check if version is updated and update information has to be shown
            JepsterVersionUtilities.checkVersion(this, mService, mPreferences);
            //Check version to verify if preference migration is needed
            PrefsMigrationUtilities.checkVersion(this, mPreferences);

            setNavigationHeader();

            mInitMainActivity = true;

            //ObjectBox need to be available, JepsterService has to be started first to be able to update schema of Box.
            if (mOnPostResume){
                selectDrawerItem(mMenuItemId);
            }
        }

Bắt đầu với stack trace tại dòng 321 của FragmentPageDataFields.java và so sánh quá trình khởi tạo chỉ đọc trong ObjectBox.initReadOnly với việc thiết lập dịch vụ từ xa. Tái hiện truy vấn trên các thiết bị Android 8.1 hoặc trong môi trường pre-launch bằng cách sử dụng thông tin chi tiết về thiết bị và các log được cung cấp.
