@ZacSweers Sorry for the inconvenience! Can you share what architecture your emulator has?

App crashing on start with below error:

To Reproduce

Internal project also but I can reproduce with the following dependencies:

Crashing:
Flipper : 0.31.0
SoLoader: 0.8.1
Fragment: androidx.fragment:fragment-ktx:1.2.2

Working:
Flipper : 0.31.0
SoLoader: 0.8.1
Fragment: androidx.fragment:fragment-ktx:1.2.1

Changing the fragment dependency seems to make it crash every time.

Expected Behaviour

No crash

Environment

Flipper : 0.31.0
Soloader : 0.8.1
Pixel 3A - Android 10

Re: @ZacSweers post above, the device we saw the issue on was a Pixel 3A.

I've got a 2XL. Will try it out on that one today. Should be close enough.

I've installed the sample app on my 2XL where it worked fine.

Additionally, I tried to add fragment-ktx in both versions which also didn't seem to make a difference and set the Flipper version to the published 0.31.0 artifacts.

Could you try to install our sample app and see if that causes the same issue on the phones / emulators you have? Annoyingly, we don't have it on the most recent releases here but it should show up soon on the one that's landing right now: https://github.com/facebook/flipper/releases (give it ~1h from now)

same issue here.

@passy But works when I install the latest android sample apk.
