Is there any way where I can recreate create SHA1 and package name to match with the old ones,
I am unable to upload app to playstore due to this.
All AppInventor-based platforms offer the option to Export / Import the Keystore
other platform app aia will not support…in niotron. you will have to remove all accept the basic things.
Go to other platform where you had build your app then export keystore and copy your pakage name from screen1 property after that go to niotron builder and upload your keystore and paste your pakage name to screen1 property.
