How to Reset Lost or Deleted .JKS File in Google Play and Update your app | Android App | Flutter |
We recommend that you adjust your planning to include a buffer period of 48 hours from when the upload key has been reset before you can use the new upload key. You can learn more about using app signing by Google Play here.
Here’s how to generate and register a new upload key:
Follow the instructions in the Android Studio Help Center to generate a new key. It must be different from any previous keys. Alternatively, you can use the following command line to generate a new key:
keytool -genkeypair -alias upload -keyalg RSA -keysize 2048 -validity 9125 -keystore keystore.jks
This key must be a 2048 bit RSA key and have 25-year validity.
Export the certificate for that key to PEM format:
keytool -export -rfc -alias upload -file upload_certificate.pem -keystore keystore.jks
Reply to this email and attach the upload_certificate.pem file.
I look forward to your response. Please let me know if you have any questions in the meantime.
