It would be so great to get more info on how to package Android correctly with bigger OBB sizes, specially using videos. I am exactly on the same page and getting the same results. I can Quick Launch de App from UE Editor but I cannot install it with the installer. Everything seems to go fine but obb file is not copied correctly (Android Studio shows a 600mb file but my generated obb file is 3.8 GB).
I have just tested that I can succesfully install the app sideloading it by copying the OBB file into /sdcard/android/obb/ and running the installer (copied anywhere inside the device). If anyone could help…
Thanks!
