How to sign Android bundle .abb?

1

If I use “Make Native App with VoltBuilder” with Android package type “bundle” I get this error when I upload the .abb file to google play.

“For new apps, Android App Bundles must be signed with an RSA key”

  1. What is an RSA key ?
  2. How to I generate an RSA key ?
  3. How do I sign my new app with this RSA key using AppStudio ?

Thank you.

I had this error message too, because I had an own keystore from year 2012 which did not contain an RSA key. Another keystore from year 2015 had an RSA key and with this keystore there was no error message. If you do not have a newer keystore with RSA key then you could build a new keystore and use it with the VoltBuilder Android keystore property.

Thank you, I was using an old keystore file which probably didnt contain RSA. I generated a new one with command prompt but now I get this build error.

Execution failed for task ':app:signReleaseBundle'.

How did you create the new keystore file?

This best way to do this is with VoltSigner.

I also tried the VoltSigner way which gives out a .p12 file but there isn’t an option for alias so build fails asking for alias.

I tried it again in command prompt (I previously missed out the alias bit) and it worked:
keytool -genkey -v -keystore android.keystore -alias nsb -keyalg RSA -keysize 2048 -validity 10000

App has now been uploaded to Google play and is waiting review.

VoltSigner defaults the alias to key0. Full details here:
