[General Questions and Answers] robrazil:
I tested the apk in virtual android of webpage https://appetize.io/ and it worked in virtual Android 6.0, 7.1, 8.1 until on android 10.

Only android 9.0 didn't work

. I don't belive that. Seems a joke.

On android 10, after install, is showed the permission screen asking to give it to the camera and the storage. After press "next", the app is open and works right. I tried changing the permissions on Android 9 but didn't work to make the app opening.

Does anyone have any idea what might be happening?

This app was created to SDK 8 (android 2.2 - Froyo)

I don't know if that can be help but below I pasted the debug log of there. I simulated in Android 4.4, 9.0 and 10, to serve as comparison between the android versions. In 4.4 and 10 versions worked, but didn't on 9 version:
