How to Generate App Bundle?

To generate an App Bundle for publishing to the Google Play Store, follow these steps:

   • On Mac/Linux, use the following command:

     keytool -genkey -v -keystore ~/upload-keystore.jks -keyalg RSA -keysize 2048 -validity 10000 -alias upload

   • On Windows, use the following command:

     keytool -genkey -v -keystore c:\Users\USER_NAME\upload-keystore.jks -storetype JKS -keyalg RSA -keysize 2048 -validity 10000 -alias upload
