我正在尝试将我的团结项目构建为APK但我有一些错误 . 我能够在一天前没有任何问题地构建同一个项目，但是，虽然从那时起我没有添加任何单行代码，但我现在有3个错误 . 我只更改了CompanyName，ProductName和发布密钥 . 而我得到的错误是：
"Failed to compile resources with the following parameters: -bootclasspath "C:\Users\hp\AppData\Local\Android\sdk\platforms\android-27\android.jar" -d "C:\Users\Public\Documents\Unity Projects\menu_tutorial\Temp\StagingArea\bin\classes" -source 1.6 -target 1.6 -encoding UTF-8 "android\support\compat\R.java" "android\support\v4\R.java" "android\support\v7\appcompat\R.java" "com\admob\plugin\R.java" "com\cagri\aydogdu\R.java" "com\google\ads\mediation\unity\R.java" "com\google\android\gms\R.java" "com\google\android\gms\admob\R.java" "com\google\android\gms\ads\impl\R.java" "com\google\android\gms\gass\R.java" "com\unity3d\ads\R.java" warning: C:\Users\hp\AppData\Local\Android\sdk\platforms\android-27\android.jar(java/lang/Object.class): major version 52 is newer than 51, the highest major version supported by this compiler.

另一个是：

我很困惑，因为我确信除了我在第一段中提到的3件事情之外，我没有改变任何东西 . 有人可以帮我解决问题吗？
