Generate signing key

If you want to upload your application on Google Play you must sign it before uploading, to generate a signing key run the following command

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

• Enter your details and be sure to remember the password.

• Once completed, an upload-keystore.jks Keystore file will be generated. Locate this file and move it to the android/app folder.

• Afterward, navigate to the android/key.properties file and replace the password with the one you used during the Keystore file generation.
