Manually installing an updated APK fails with “signatures do not match the previously installed version”

Question

I\'ve built a silly app to share among a few friends. No need to put it up on the app-store.

I built the first apk (signed), uploaded it to a web-server

Answer 1

I got that error while trying to install release while signing it's certificate.

fixed with the :app Gradle task uninstallRelease and then installRelease again
