Android SDK没有正确安装错误，当我试图为一个游戏建立apk文件时，我正在用Unity开发？

Question

每次我尝试构建APK文件以导出到android设备上时，Unity都会给我一条错误消息，说明它无法构建APK文件，并且我应该确保android sdk配置正确。然而，我已经通过Oracle或Android studio多次重新安装了最新的sdk，但我总是收到同样的错误消息。我可以在Unity编辑器中很好地测试游戏，但每次我尝试导出时都会遇到问题。它还在“外部工具”下的首选项中声明，我没有使用正确的android sdk工具和ndk工具，不过，就像我说的那样，我已经尝试安装正确的工具多次，甚至重新安装了所有工具，但我总是得到同样的错误。

这是我在Unity编辑器中打开项目时得到的错误消息：

Answer 1

1/Android SDK

在您的第一个输出中，您的路径似乎没有正确设置。您检查过路径'D:\android\build-tools'存在吗？

通常，使用Android Studio的常规安装会将SDK安装到

在Unity中，您可以通过编辑->首选项->外部工具，并设置Android SDK路径在Unity中设置此路径。

2/Android SDK版本

确保您在Unity中针对的SDK版本（播放器设置->其他设置->最低API级别和目标API级别）与您使用Android Studio下载的SDK相同。

4/包名称和签名

您的第二个错误说‘签名不匹配以前安装的版本’。您可能已经在您的设备上安装了一个版本，并使用不同的密钥进行了签名。您需要完全删除设备上的应用程序来解决此问题。看这个帖子。
