Build for phones/tablets: Is it possible to reduce a volume of "executive" file?

I’ve tried to build a simple game for Android and it gives me an apk file which has a size: 110mb. It’s too big file for GooglePlay. I didn’t try to build a version for iOS I think it will have similar size.

Have anyone experience in reducing a size of final “executive” file (e.g. apk for android) for mobile phones and tablet?

Well, in the release notes for UE 4.8, they mentioned something about .pak files that you can package, Google Play lets you upload those on the dialog after you upload your main .apk . As far as I know, the user downloads the app, and then the app downloads the .pak files.

But the total downloaded size will be about 100-110mb? Or it compresses packages in some way?

I believe the total size remains the same, but it just allows you to exceed the 50MB max APK size for Google Play.

But it’s too big for mobile users. It’s really a big problem to have such big apk file. It depends on how many downloads you will get for this game. A big file size almost often means very few downloads.

Well, I am not completely sure, but maybe UE4 is packaging files that are not in use? How big of a game do you have? How about graphics? Making games for mobile requires you to compress all of your files before-hand if it is a big game.

There’s some file in the APK package called something like this: libCore_UE4.so - it weights 70mb. I think the weight of that file cannot be reduced?

I’m guessing it cannot, if that’s the file that is taking up so much space, then i guess there is not much more I can do to try and help :frowning:

I’ve heard that in 4.9 UE4’s developers going to make some modular system where we will have an ability to remove those modules from final build which we don’t actually need in the build. Is this real? Have you heard something about it?

UE4 is already modular if you didn’t notice yet, but you need to play with build scripts to make it not build unneeded stuff

No I didn’t notice yet about it :slight_smile: Could you please provide me with some more information on this? Maybe you can give me some link?
I know that UE4’s Flappy Bird has a weight about 20mb. I don’t know how they do it but it’s really cool stuff I wanna make such things too :slight_smile:
