downgrading back to Flipper 0.76.0 works successfully.

This is a regular Android app and not a RN app

I meet the same bug in 0.78.0.

cc @passy might this be related to the recent build setup changes for fbjni?

[passy]

Yes, there have been changes to the distribution but I tested this with our sample apps and it worked without additional changes. Would be great to have a sample project that repros the crash.

[matheuskiser]

Same issue in 0.79.0.

[passy]

Again, I will need a sample that repros this.

[zws33]

I experienced this issue with my app, as well as the sample app in the repo. The latest version that worked for me was 0.76.0.

[mweststrate]

If the issue is also experienced with our sample app, it might be an environmental issue, as we'll always build that one as well in our CI were it succeeds happily, for example https://github.com/facebook/flipper/runs/2025667652. So it might good to compare your local setup (gradle, ndk, jdk versions etc) against our CI setup which is a pretty isolated but working setup: https://github.com/facebook/flipper/blob/master/.github/workflows/android-sample.yml

Running into this as well, created a minimal repro

[passy]

Thanks, @steelahhh. I'll check that out today.

[passy]

That helped a lot, @steelahhh. Thanks for that. It looks like prefab behaves differently when used through an exported package and when consumed as part of the same gradle project.

Ultimately, this is something the Android Gradle plugin will need to fix. For now, what we could do is include libfbjni.so as part of the Flipper package. That feels a little icky to me, but would at least help as a workaround here. I'll check out some other options but that might be what we need to do.

[passy]

I'll address this through a new fbjni release instead. In my testing this seems to work both in the Flipper repo and with your app. https://github.com/facebookincubator/fbjni/pull/51

Ran into this issue with 0.79.0. Is this fixed with 0.79.1 release?
Works with 0.79.1 👍
