علت حجم بالای خروجی اندروید در بازی های یونتیی 5

منبع:gameover.blog.ir

نکته اول:
ابتدا از پنجره ی  build به مسیر Player Settings -> Other Settings -> Device Filter برید.
اگه تنظیم devcie f_il_t_er روی هر دو حالت باشه یعنی both ARM and x86 پس حجم بالاتر می ره ولی در عوض روی هر دو پردازنده ی گوشی های هم x86 و هم ARM بازی نصب خواهد شد و بنابراین صرفا بالابودن حجم دلیل بر بد بودن نیست چون بعضی اوقات حتی لازمه برای اینکه مطمئن بشیم بازیمون روی اکثر گوشی ها اجرا میشه.


نکته بعدی:

بعد از build به apk ،در قسمت بالا و سمت راست پنجره ی console لاگ یا نوشته ها روی فلش کوچک پایین بزنید یک گزینه Editor Log رو می بینید.روش بزنید می گه چند درصد مربوط به کدوم بخش هست.

Yes, Unity should make this critical information way more obvious!

Sometimes it's as simple as a texture you have forgotten to downscale, or a model that needs to have Compression turned on (model and/or animation). Sometimes you've inadvertently depended upon an expensive DLL (like XML). Sometimes a package you're using (like Detonator) has a lot of big unused Resources (unused mere assets don't matter).

Note on the above sizes: these are for a WebPlayer; unlike Android and iOS, web builds don't have to include the Player, since the user installs that separately (I suspect that's actually the entirety of your "problem").
