If you generate an apk and it doesn't even install (because of the message you get) check if you have a previous version installed. If so you can either:

  1. Uninstall de previous version and install the new one
  2. Change the version code in Manifest, it has to be greater to the current one. You should also check (if you sign the apk) that the key is the same, I had a similar problem.

Other causes could be:

  • Check that the minSdk is equal or lower than 30 (Android 11) to garantee your device is compatible
  • How big is your app? Maybe you don't have enough space in your device
  • Maybe your .apk file is just corrupted, try to compile it again

In android studio, Build option-> Build Bundle(s) -> Build Bundle's / Build APK's -> Build APK's

I have installed that build APK, finally installed
