Onsen UI APK signing certificates expire soon

[Leonardo Augusto]

Hi guys. i’ll send my first Onsen UI apk to Google play. But i’m receiving this error:

certificates expire too soon, send other apk.

My apk is signed how you can see , image below and was made in visual studio.

my code to sign using jarsigner:

key.store=c:\\mykey-key.keystore
key.alias=myalias
key.store.password= *******
key.alias.password= *******

and my keystore

 keytool -genkey -v -keystore c:\mykey-key.keystore -alias myalias
 -keyalg RSA -keysize 2048 -validity 10000

Lol with validity = 50000 is everything okay now . thanks everyone.
But , tips are welcome.
