Hello all. I’ve just started with Unity and I’m confused by the file size of my first build which is for Android. So I went through part of the Roll-a-ball tut and built it. File size is 17.5 MB which seems rather enormous to me. Then I loaded said APK onto my phone and then on the phone checked the app size it’s info says 55.46 MB. This is for a plane, sphere, camera, and a light. No textures or sound files. No imported meshes etc. Wow, that’s bigger than a full app like “Toca Kitchen” which is about 37 MB. Can someone enlighten me on this please? Thanks.
Unity now targets both ARM and x86 Android devices. The default setting is to target both. Select ARM Only and the file size should decrease.
