Thank you. That works.
The most helpful part was that you do NOT check of the boxes for the files which you manually put in the mods folder. Just put them there, but do not check the box. No configuration needed in other words.
Checking the box makes it try to download it, which was giving me the problems.

Now I'm on to the next challenge.
It works great in landscape mode, but the portrait mode does not work.
By playing with the different settings during startup and graphics settings in the game I could either get the graphics to show larger than the entire screen, like a tall vert narrow strip, compressed on the X-axis, or half the graphic showing starting at the left edge but the right half of the graphics disappearing over to the right side of the screen.
I've got a Motorola G100.
Perhaps it is not worth playing with.
I also noticed that sliding the finger for the pad in portrait mode will also push the button when sliding over it.
There seem to be a few issues with portrait mode. But perhaps nobody else wants to use it anyway...

Thank you!

Unfortunately (Android), after copying the files to the addon folder, and selecting them in the Options menu, the game still tries to download them, and complains about the download failling, never entering the game.
Is there a way to work around it?

Hello, Serosis.

For the Android release, after installing the APK, is it possible to add the mod files such as
mm-0.8.2-hd.uqm
or
mm-0.8.2-3dovoice.uqm

manually to the app by copying them to a specific folder?
If so, could you explain which folder or how to do this?
(The in-app download is unfortunately unavailable to me due to network restrictions, and by downloading them one time I could also easy copy them to multiple Android clients)

Thank you!
