I have generated my apk as it is stated in the react-native documentation and it does not give me problems at any time, I run the command react-native run-android --variant = release and it works perfectly in the emulator, but when I install the apk in the emulator or in my phone the icon does not appear to me by any side and I can not ejectuarla, if I put in the configuration to uninstall the app that I have just installed if it appears but by no other side I can see it to be able to execute it, any help or idea is grateful.
