Question

I\'ve found the following error when running my android application in android studio. app couldn\'t get installed on my device because of this error. Didn\'t find the solut

Answer 1

I got this error when tried to install app directly from Android Studio.
It was due to certificate mismatch, since I used release certificate for setting up the app in Play Console, while Android Studio signs the app with debug certificate by default.
Installing app via adb resolved the error.

Make sure to run an APK that you exported and signed with a certificate that matches one of the certificates you used during the application setup in Google Play Console.
