Initially I was attempting to launch the game directly to my device and there were some obscure errors so I opted to do what you suggested and just package it and manually install the apk and obb file.
There were a number of things that I wasn’t aware of, such as the fact that the name you give your android release has to match whatever name you chose for you unreal project exactly. If not the game would fail to launch with **Assertion failed: HasFoundDataDirectory [File:D:\BuildFarm\buildmachine_++depot+UE4-Releases+4.9\Engine\Source\Runtime\Core\Private\Internationalization\ICUInternationalization.cpp] [Line: 117] **
I only figured out what caused this by googling it. Oddly enough the obb file can have a different name.
There were lots of little things like that which I only discovered after attaching logcat to see what was happening on the device.
So I got it installed and running finally but there were a couple of concerns right off the bat. The size of the obb file is almost 500MB. I really hope that it’s possible to reduce that because it seems insane for such a small project. The other is that multi-touch does not seem to be supported, which makes a platforming game impossible to play on a touch screen device. I’ll dig around more when I get a chance but I’m really looking forward to using this kit once I can get past these initial problems.
