By mistake I deleted the keystore plaese give me my old keystore please i request you 
That’s not possible.
Kodular administrators can give ??
But you can import a new KeyStore.Can’t you?
Okey Please give me new keystore
Yeah but you won’t be able to update existing apps on any app store
Yes I know
Ok, then generate a new one
How to generate ??
If you want to update an app that is already published in the Play Store with your old (lost) keystore, then you must ask Google to assign a new keystore to be able to release your app in the Play Store:
This is only possible if the app is enrolled into Google Play App Signing program.
If I remember the keystore, you can give the same keystore by generating ??
If your app is published on 
then you can see your keystore
If your app is on play store then you will get your keystore
Go to app signing option
Then download your keystore
I did not tried this trick but i think it will work
What is only possible?
(Does your message relate to my statement?)
