1，values-v31.xml:5: error: style attribute 'android:attr/windowSplashScreenBac
是因为SplashScreen是android12中加入的，所以需指定android12版的SdkVersion
解决办法：targetSdkVersion升到31
targetSdkVersion 31
对应的 compileSdkVersion 31
2，unrecognized Attribute name MODULE (class com.sun.tools.javac.util.UnsharedNameTabl
这是升级targetSdkVersion 31所导致的问题，应该是android12需要至少JDK11
解决办法：
Path to update your gradle jdk in AS Arctic Fox:
Settings > Build, Execution, Deployment > Build Tools > Gradle > Gradle JDK
Select 11 and build should be successful.
