I have now created an extension that can also be used to download and install an APK with AI2 (using AndroidX libs). It should work with all versions of Android. The given download link (GoogleDrive) downloads an almost empty APK (only one button, 3.2 MB). But you can also set your own link to your app (APK).
So check that on your devices with different Android versions, especially Android 10 and 11.
Taifun.
If i am right the emulated SDcard dir looks like this:
I tried to install from this with KIO4. Doesnt work.
By the way DeepHost's custom download also save the file to emaulated dir. I checked it. It gives the same error with that too.
But seem Anke solved the problem. I'm just waiting for the aix download link.
I would like a few successful tests with Android 10 and or 11 beforehand to see whether it works on different devices with Android 10 or 11. So maybe someone will be nice enough to check it out.
It works on my Pixel 2 XL (Android 11 beta).
