Update app without downloading apk file again

I have a question that if I made a kodular app/game then I downloaded the apk file. After the download, I did some changes to my app. But when I open the apk file the changes are not made but if I want to make the changes then I need to download the apk file again. But how can I update my kodular app/game without downloading the apk file again?

If the thing you want to change is content such as text or images, you can create your app dynamically and use firebase to update content.

Can it be without Firebase?

Yes you can use Airtable.

Any online database can be used.

Can a component be used to update?
