All my apps run perfectly on the iOS simulator and use to work for the android emulator, but now they don't.

This is what happens when I try run any app, including the flutter demo app, on the android emulator API 29. When I run it on the iOS simulator everything works perfectly and this does not happen. Do you know how I can fix this?

Hi @AlessandroPalmarini can you please provide your flutter doctor -v and your flutter run --verbose? Also, to better address the issue, would be helpful if you could post a minimal code sample or the steps to reproduce the problem. Thank you

Hi @iapicca I ended up uninstalling the emulator and creating a new one with the API level 28 instead of 29 and the issue went away for me. Sorry that I couldn't help you to reproduce the problem.

Hi @AlessandroPalmarini I'm glad that you found a workaround I'm closing the issue for the moment, let me know if the problem occurs again thank you
