Adding the Paparazzi plugin to a module that tests Molecule presenters leads to UnsatisfiedLinkError #111

Not really sure whether it's a Molecule or a Paparazzi issue, or something else entirely, so starting a discussion first before filing an issue. Chose to start a discussion on this project cause the issue I'm seeing manifests in the Molecule code.

I set up a test project that includes a simple @Composable presenter and unit tests for it, the tests launch the presenter using CoroutineScope.launchMolecule and use Turbine to test it. You can check that the tests pass by running ./gradlew lib:tDUT.

But if I simply add the Paparazzi plugin to the same module, tests start failing with the following error:

Caused by: java.lang.UnsatisfiedLinkError: 'long android.os.Trace.nativeGetEnabledTags()'

Full stack trace

Not really sure what's going on. Any ideas?

Paparazzi is replacing the stubbed APIs with real ones via layoutlib and it doesn't support this particular API that the Compose runtime uses. Seems like a Paparazzi feature request is in order.

Interesting, makes sense! Will file a Paparazzi issue.

@Egorand I just ran into this as well but couldn't find the issue filed on paparazzi. Should I file one just linked to this?

@burntcookie90 looks like I forgot to file it after all.. Sure, please file if you're still seeing this!
