Any tips to reduce apk size while building

[raje150]

hi,

i m total new to playmaker and unity itself. trying my hands on android game development. . i just made a simple bare bones flappy bird kind game with 2d assets. its just to learn the both softwares. i got the file size of 15 mb. i consider its small but with just 3 or 4  2d assets, i think its still big. flappy game in play store is 4 mb i guess.

so basically any tips to reduce the game size. does playmaker makes the game bigger? i ll attach the game file and the project file here. if any one have time, take a look and give me feedbacks on better build options. Thanks. (the studio name in the game is a joke ) and i saw the tutorial in hutong to build this game and tweaked a little of my own. and i used unity beta 5.5.0b5

(i don't know the support in other mobiles. i use moto e . i created for that)

Hi, you should not share the playmaker.dll file in the plugins folder

One thing what you should do is place your images into 1 image and use multiple sprite mode, then you can edit them with the sprite editor and cut them out.
and you can set the format to crunched

Hi tht seems good idea. And seriously what's with playmaker.dll . I don't even know wat u jus said. Can u pls tell me why and where it is to be removed ?

Hi,
The playmaker.dll is inside the 'plugin' folder.

The reason why this is not allowed to be shared is that playmaker is a paid asset.
and if you share it, anybody can use it (even if you don't have playmaker) on that project.

This applies to all assets btw.

Hi,
Actually not to all assets, the free asset is no problem as far as i know
