UnsatisfiedLinkError: couldn't find "librealmc.so" #1202

Open KennethRichards opened 1 year ago

SDK: realm-kotlin

Version: 'io.realm.kotlin:library-sync:1.5.0', 'io.realm.kotlin:gradle-plugin:1.5.0'

Observations

How frequent do the crash occur? Subset of users
Does it happen in production or during dev/test? Production
Can the crash be reproduced by you? No. I was unable to reproduce in the Android Emulator on Nexus 7 - Android 8.1
Can you provide instructions for how we can reproduce it? Seems to be occuring on app launch when calling App.create()

In the APK, librealmc.so exists in /lib/x86_64 /lib/x86 /lib/arm64-v8a /lib/armeabi-v7a

rorbech commented 1 year ago

Hi @KennethRichards Since this only happens on some devices it could be that the so-file for some reason is stripped by Google play when installing the app. Do you have more insight in:

The suite of devices that this appears on,
How many of your users it happens for
Any other patterns ... If the devices are root, etc.

KennethRichards commented 1 year ago

Hi @rorbech This is only happening on the Nexus 5X (Android 8.1.0) and Galaxy Tab A (Android 7.1.2). <1% of users are affected with only 1 of these users being rooted on a Galaxy Tab A. No other patterns for now, but I will continue to monitor

rorbech commented 1 year ago

Hi @KennethRichards. Thanks for the feedback. Are you by any chance distributing other native libraries than ours in your app? We have seen that if some other library is not available for the exact architecture then it can end up only looking for 32-bit libraries on a 64-bit device, and that library could have been stripped as part of the repackaging in playstore.

KennethRichards commented 1 year ago

Hi @rorbech, I checked the Github repos from the other dependencies in our app but did not find any indication of native libraries. To be honest I'm not quite sure how else to check/verify this.

When inspecting the APK though, I can see that librealmc.so is the only file located in the following directories: /lib/x86_64 /lib/x86 /lib/arm64-v8a /lib/armeabi-v7a

cmelchior commented 1 year ago

We have seen a similar problem with Realm Java, and the root cause is still unclear. It is pretty rare, but our best guess is that either APK's are being side-loaded in the wrong way or the Play Store doesn't send down the correct files.

Currently, in Realm Kotlin, we are just loading the native lib in a naive way, which should work, but has a few known edge cases, #1215 will introduce a slightly better way, but it isn't a 100% guarantee it will fix this issue.

cmelchior commented 1 year ago

The problem with this error is that we think this is related to the Playstore distribution and App Bundles and sometimes the app store sends the wrong thing to devices. Unfortunately, this is basically impossible to test and we have never been able to reproduce it.

At the same time, we have seen people manually distributing the wrong app bundles to devices, but this normally happens with custom app distribution frameworks or rooted devices where you try to sideload an APK.

That said, we just pushed a change that is available in 1.10-SNAPSHOT which disables Relinker above API 22. The reason we use Relinker is that Android has known bugs loading native code on API 22 and below, but there is no need to use it above.

So just to be 100% sure this library is not involved in these bugs, it has now been disabled.

Apart from that, the solution we have seen working is to disable App Bundles, unfortunately, the tradeoff there is an increase in APK size.

Ynnck123 commented 5 months ago

Are there any updates on this issue or the proposed fix of disabling app bundles? We are also experience this error in one of our production apps.

Devices are for example OnePlus 9 5G with Android 14; Realm Kotlin version currently 1.12.0. Maybe there are fixes in an already released version? The issue is still set to be open therefore I assume it's not fixed yet?

ponvig commented 5 months ago

Same here on Nexus 5X (Android 8.1.0) and Pixel 6 Pro (Android 12):

The problem with this error is that we think this is related to the Playstore distribution and App Bundles and sometimes the app store sends the wrong thing to devices. Unfortunately, this is basically impossible to test and we have never been able to reproduce it.

At the same time, we have seen people manually distributing the wrong app bundles to devices, but this normally happens with custom app distribution frameworks or rooted devices where you try to sideload an APK.

That said, we just pushed a change that is available in 1.10-SNAPSHOT which disables Relinker above API 22. The reason we use Relinker is that Android has known bugs loading native code on API 22 and below, but there is no need to use it above.

So just to be 100% sure this library is not involved in these bugs, it has now been disabled.

Apart from that, the solution we have seen working is to disable App Bundles, unfortunately, the tradeoff there is an increase in APK size.

Based on this reply, if it's really because of the Play Store Distribution: Maybe the cause is based on users downloading the app's from third party stores and not from the official Play Store and therefore this file is missing on their installations?

Has anyone subscribed to this topic been able to reproduce this issue? I assume that everyone here is just posting the stacktraces from the crash monitoring of their choice

I've not been able to reproduce it personally but would like to suggest we rule out the third party stores theory: I get the crashes reported within hours of posting a new release, which I only publish to the Play Store. Unless some third party store picks it up immediately, these are Play Store installations.

Also, the ratio of these crashes for me is about 0.1% of my active users. That's not too bad, but it's still frustrating.

I also noticed that Google closed the ticket that was mentioned earlier.

I have precisely the same crash, and also Nexus 5X Android 8.1.0. Also cannot re-produce on emulator. Realm version: io.realm.kotlin:library-base:1.16.0
