What dost code in "Java_io_objectbox_query_Query_nativeRemove+68" do?
Once crash happen, the same user will crash many times.

my code:

    private fun deleteExpireTimeData() {
        try {
            val splitTime =
                System.currentTimeMillis() / 1000 - AppConfigManager.getOnlineMaxSaveTime()
            val count = getOnlineUserBox().query()
                .less(OnlineNoticeUserEntity_.pullServerTime, splitTime)
                .build()
                .remove()
        } catch (e: Exception) {
            val dir = onlineDataDir()
            FileUtils.delete(dir)
        }
    }

It's crash when 'remove' invoke

Thanks for reporting! It would really help if you can provide the info requested in the bug report template, most importantly which version of ObjectBox is used by your project?

Anyhow, the most common cause for this, that we are aware of, is that the Store is closed in a different thread while the remove query is still running.

Note: I labeled this issue with "more info required" so it will auto-close in a few days if there are no follow-up comments.

Build info
ObjectBox version: [3.8.0]
OS: [Android 28/29/30 ]
Device/ABI/architecture: [arm64-v8a / armeabi-v7a / armeabi(8 Cores)]

Recently, it's crash 101 times in 3 phones as below:
HUAWEI EVR-AN00, Android 29
vivo V1945A, Android 28
OPPO PECM30, Android 31

Steps to reproduce
when the app launch and invoke 'remove' method`

    private fun deleteExpireTimeData() {
        try {
            val splitTime =
                System.currentTimeMillis() / 1000 - AppConfigManager.getOnlineMaxSaveTime()
            val count = getOnlineUserBox().query()
                .less(OnlineNoticeUserEntity_.pullServerTime, splitTime)
                .build()
                .remove()
        } catch (e: Exception) {
            val dir = onlineDataDir()
            FileUtils.delete(dir)
        }
    }

the stack traces is in the first message

objectboxVersion = '3.8.0'

Based on the symbolized crash dump ending in LMDB code, this likely is as I suspected because the Store gets closed while a query is running.

The latest release has improvements for that case. My recommendation is to update to the latest version (4.0.3 as of 2024-11-04).

Note: I labeled this issue with "more info required" so it will auto-close in a few days if there are no follow-up comments.

Thanks, I will try it in next version of our app.
