unity3d2021.3.11f1生成android的APK遇到的问题及解决方法

前提：windows电脑，unity3d2021.3.11f1 长期支持版本LTS

先说说遇到的问题：构建apk时卡半天，然后出现报错，在console窗口看详细问题，因为问题已经解决了，错误日志被刷掉了，这里借用一个国外大佬的错误信息，除了版本，其他和我的基本一样。又需要的也可以去看看原文（可能需要科学上网）：java – Unity 2021.3.4f1 Gradle Build failed – Stack Overflow

对比一下上面的错误日志，看看是不是和你的一样，日志是不是眼花缭乱，其实去里面找关键信息就行了，以下就是这次问题的原因

* What went wrong:
Execution failed for task ':launcher:packageRelease'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade
   > com.android.ide.common.signing.KeytoolException: Failed to read key AndroidDebugKey from store "C:UsersSamprit Hazra.androiddebug.keystore": Invalid keystore format

大致意思就是无法从存储“C:UsersSamprit Hazra.androiddebug.keystore”读取密钥 AndroidDebugKey：密钥库格式无效。

那么知道了原因就好解决了，直接来个暴力解决方法，既然他无效，那我们就把他干掉

直接删除debug.keystore。

先退出unity3d，在退出之前先从console窗口里的日志中找到debug.keystore所在的路径，比如上面这个C:UsersSamprit Hazra.androiddebug.keystore，然后直接Delete他。

删完后重启unity3d，再次打包apk，你就会发现OK了！
