APK signed by more certificates


Hi guys,
I have a problem with the upload of my APK. I executed the following steps:

  • created cert with keytool (I created it for previous app. The app is already published)
  • I signed the APK with jarsigner command
  • I validate APK with zipalign

When I upload apk on Google Developer Tool, I receive this error message: “Il tuo APK è stato firmato con più certificati” (italian language)… translated: “Your APK signed by more certificates”.

Help me please


How did you build your app?
