Hi @Jyoshnarani

What version of Realm? (2.0.0?)

Device or emulator (or both)?

Did the problem occur after upgrading an existing project, or when creating a new one?

If upgrading, then from what version?

Did you try flutter clean?

If that didn't help. Did you try re-creating the android project:

rm -rf android
flutter create . --platforms=android # ,...

[Jyoshnarani]

Hello @nielsenko

What version of Realm? (2.0.0?) - 2.0.0 (I faced issue in 1.9.0 also)
Device or emulator (or both)? - both
Did the problem occur after upgrading an existing project, or when creating a new one? - existing project
If upgrading, then from what version? - 1.8.0
Did you try flutter clean? - yes

[nielsenko]

@Jyoshnarani What desktop are you on? The instructions for re-creating the android flutter project is for macos, and linux.

[Jyoshnarani]

@nielsenko , It's android flutter project

[nielsenko]

Yes, but your development machine? What OS is that?

[Jyoshnarani]

Desktop - Windows

[nielsenko]

Could you try re-creating the android platform project, and report back?

[nielsenko]

I have tried upgrading and downgrading between 1.8.0, 1.9.0, and 2.0.0 and running on an android emulator.

Apart from the breaking change, regarding naming of part files (x.realm.dart instead of x.g.dart) introduced in 2.0.0, it went without any hickups.

I'll need further info to proceed with this.

[Jyoshnarani]

@nielsenko ,

Yes you can ask which details you need from my end.

[nielsenko]

Hi @Jyoshnarani

Could you try re-creating the android platform project, and report back?

[Jyoshnarani]

@nielsenko !

I check with new project and I went through x.realm.dart also.

But same error.

[Jyoshnarani]

Dart version is same

Package :
realm_dart: 2.0.0

[nielsenko]

Could you do flutter clean again, and then attach the output from flutter build apk?

[nielsenko]

What files do you see below:

%LOCALAPPDATA%\Pub\Cache\hosted\pub.dev\realm-2.0.0\android\src\main\cpp\lib

[Jyoshnarani]

Here it is.

[nielsenko]

Sorry, recursively?

[Jyoshnarani]

Ok, But Is there any solution?

Exiting Project is in live.

I'm facing this issue since last 2 days.

[nielsenko]

Erhh 2.0.0 was released yesterday? You are the only one I know of with this problem?

[nielsenko]

Apparently the app cannot load the shared library that is the core of the realm database.

Given, what you have already tried I suspect that it somehow doesn't get bundled at all. Hence why I want to see the files I requested, since that is where the file will be downloaded to.

You can also try to unzip the .apk and see if you can find it in there. It should be, actually 4 versions of it:

lib/arm64-v8a/librealm_dart.so
lib/armeabi-v7a/librealm_dart.so
lib/x86/librealm_dart.so
lib/x86_64/librealm_dart.so

[Jyoshnarani]

Can you say what is the means of the error.

Invalid argument(s): Failed to load dynamic library '/system/bin/librealm_dart.so': dlopen failed: library "/system/bin/librealm_dart.so" not found

[nielsenko]

It fails to load the dynamic library as I said. It will look for it in multiple places.

[Jyoshnarani]

One of my colleague, He tried and he faced below error.

[nielsenko]

Are you by any chance running the same project?

[Jyoshnarani]

No in another project (New) he is using same package.

Deferent windows.

[nielsenko]

If it is a brand new project, I assume he could bundle it up in a zip file and attach it here. Then I can take a look.

Including the build folder, please.

[Jyoshnarani]

untitled.zip
last_build_run.json

[Jyoshnarani]

With build its 600 MB - so unable to upload

[nielsenko]

Could you upload just the generated .apk? It should be less than 40MIB I guess.

Not sure what the last_build_run.json is. It is just 27B and contains only: ["--track-widget-creation"]

EDIT: No need for this!

[nielsenko]

Could you please update your pubspec.yaml to take a dependency on realm? Currently you only have a dependency on realm_dart. The realm package makes sure that your app includes the native library.

[Jyoshnarani]

release.zip

[nielsenko]

So adding a dep on realm fixed the project in untitled.zip that you uploaded. Can you confirm, the same for you other project?
