QUICK UPDATE: Just checked http://play.mob.org/game/mortal_kombat_x.html( I know I ain't mean't to link to external resources, but given that the game itself is free... Well, do the bloody math ). The Android version does in fact contain an .obb file. Either copy the .obb from your phone by attaching the USB and selecting "Android/obb/com.mkx"( might be that directory ), or re-download one of the ones from this website. Rename the extension from .obb to .zip. Extract, than copy the contents of umodel: "Umodel.exe", "SDL2.dll" to the "cookediphone" folder, double click "Umodel.exe" and check off "zlib" in the bottom left corner of the window, and check off "Android" in the bottom right corner.
MAKE SURE THAT "ANIMATIONS" is deselected... Animations are not supported with MK-X / Injustice. Keeping this selected, will cause the program to crash and you will have to set it up again. Also, keep in mind that although Umodel works with the .ipa version of MK-X, this may not be the case for the Android version. Case in point: Batman: Arkham City Lockdown.
