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

To me, if the app is meant to be distributed, the adb solution is a no-go: you can't ask one's friend to have the android sdk installed on their machine !

The way to go here is to edit the AndroidManifest.xml and to increment the android:versionCodeattribute in the tag (which is the root element).

This would update your installed application
