## 前言
Unity 升 2020 之後 build Android 有一些問題，各有對應的地方要修改，但是讓 unity 把全部 gradle 重新產一遍就可以全部解決

參考 PR: https://github.com/fourdesire/bedtime-client/compare/feature/0.6.0...feature/0.6.0-i-refine_android_gradle_template

## Problem 1


ref: https://answers.unity.com/questions/1802208/build-error-27.html

For Unity 2021.1 and Android 10 I use mainTemplate.gradle for my project and here I changed to this:

 aaptOptions {
         noCompress = ['.ress', '.resource', '.obb'] + unityStreamingAssets.tokenize(', ')
         ignoreAssetsPattern = "!.svn:!.git:!.ds_store:!*.scc:.*:!CVS:!thumbs.db:!picasa.ini:!*~"
     }

from this:

 aaptOptions {
         ignoreAssetsPattern = "!.svn:!.git:!.ds_store:!*.scc:.*:!CVS:!thumbs.db:!picasa.ini:!*~"
     }

## Problem 2


NOTE:
解到這個的時候試了把全部的 gradle 重新產一遍，問題就都解決了，就暫時沒繼續找每一個問題對應的地方了。
