No -tsa or -tsacert is provided and this jar is not timestamped. Without a timestamp, users may not be able to validate this jar after the signer certificate's expiration date (2046-05-12) or after any future revocation date.


where is the error?
In case you mean the warning, then you can ignore it, as long you do not need nothing mentioned in the warning, for example on black *day 2046-05-13 every user will %&$§& you.
see tsa -> time stamp authority.

Best xmas, anna-liebt

please explain more
I’m introductory

Google, Bing etc is your friend, because I am also beginer with this things.
You can deploy your apk, but users are not able to start the app after the date mentioned in the warning.

Best regards, anna-liebt


Well, I’m also getting the same warning. In my case, by mistake, I entered the wrong password more two times, so only I started receiving this warning. I’m also a beginner.
