The same issue.

[yd-threra-and]

We are also encountering this issue with the Realm SDK on Android 15 emulators with 16 KB page sizes.

We are in the middle of developing our next official release that will support Android 15, and this issue is critical for our progress. Could you please provide any updates on the status of this issue? Is there a planned fix for both the Java and Kotlin SDKs?

[victorjimbei]

A similar issue for the kotlin version is in progress.

I saw a similar crash with an unrelated cause. I was able to fix it in our NDK project by following the Android guide, Support 16 KB page sizes.

So, is this project now abandoned by MongoDB? This issue here will break all apps using Realm on Android devices with the new 16KB page size and they don't even care.

Yes, it's almost 2 months, and still no update on this. Really !!!

I ended up compiling Realm myself with the 16 KB page size flags, and this caused our crash on launch to go away. While it's a pretty simple change, it needs some more thorough testing (esp. with the object server library, which we aren't using in our project). #7897

[ABINAYASEL]

I am facing same issue, when will be the new version released with this fix?

[victorjimbei]

Are there plans to release a new version with this fix in place?
