Android Phone compatibility problem

Hello, I made a phone game. But it doesn’t support below android 8.1 version. It is not compatible. It gives an error on the upload side. Can someone with relevant knowledge on this issue help? I am using Unreal version 4.26.

You can set minimum SDK version as 9 (ie: Gingerbread). But, its better to identify which version you’re targetting. Based on that you should set the SDK verison.

is it this way ? Do I have to do anything else?

It is enough for me to support up to version 19, but when I do it, I have a compatibility problem.

Yea! and also make sure those SDK are ready for it.

I could not fully understand. How will I control your readiness?
