As titled. I’m currently learning to develop 2d platformer game in android. However, the apk size is too big (around 28 MB). The game itself have no audio, have only a little of sprites, and only 2 levels.
The biggest assets you probably have, are textures. Make sure all your sprites and textures are compressed, or if you can, move them to be on 1 single texture that you can just pull from.
And if possible, try cutting out 1 of your scenes. If the 1st one is just a menu, make it a UI overlaying the entire scene, and just pause the game behind it. Unity scenes, even if they’re empty, still take up space.
