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
Luca
How did you build your app?
If you want to sign an APK more than once, just do so. But note that Google Play does not accept APKs with multiple signatures. Application signing allows developers to identify the author of the sign language alphabet application and to update their application without creating complicated interfaces and permissions. Every application that is run on the Android platform must be signed by the developer.One of the cornerstones of Android security is that all apps must be digitally signed. Application developers sign apps using a private key in the form of a certificate.
