Error jarsigner android release


I’m trying ti publish my app on the Play Store. I’m using this tutorial :

When I execute the jarsigner command, I have an warning after execution :

No -tsa or -tsacert is provided and this jar is not timestamped. W
tamp, users may not be able to validate this jar after the signer
expiration date (2042-10-18) or after any future revocation date.

My command is

jarsigner.exe -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore my-release-key.keystore MainActivity-release-unsigned.apk alias_name

Is it normal ?

Thanx for your help :slight_smile:

Looks like a warning they added in a recent JDK release: JDK-8023338

I think it’s safe to ignore when signing Android apps.
