Hot to install APK's with Automagic

[Hello]

I try to install apps automatically. I tried the example in "Activity start", but the package installer flashes only briefly and the install button is not displayed. What do I have to do to make it work? Android 8.0

[Hello]

Thanks I have seen you had the same question. I have it read too.
I've been sitting there for weeks wondering how to do that and thinking all along that it's my mistake that I could have saved my time.
