Build Android app Failed

Hi Experts, Google Play is not accepting the AAB because of this issue (Your app currently targets API level 30 and must target at least API level 31 to ensure that it is built on the latest APIs optimised for security and performance. Change your app's target API level to at least 31) and I changed the build.gradle like the below: buildscript {     ext {         buildToolsVersion = "31.0.0"         minSdkVersion = 21         compileSdkVersion = 31         targetSdkVersion = 31         kotlinVersion = "1.3.50"         excludeAppGlideModule = true         playServicesVersion = "16.1.0"         androidXCore = "1.6.0"         androidXAnnotation = "1.5.0"         androidXBrowser = "1.4.0"     } but when I tried to build the android app faild and the below error in log: 3-02-27T14:26:32.5787350Z FAILURE: Build failed with an exception. 2023-02-27T14:26:32.5830910Z  2023-02-27T14:26:32.5861890Z * What went wrong: 2023-02-27T14:26:32.5873760Z Execution failed for task ':app:compileAppstoreReleaseJavaWithJavac'. 2023-02-27T14:26:32.5893440Z > Compilation failed; see the compiler error output for details. 2023-02-27T14:26:32.5916800Z  2023-02-27T14:26:32.5935830Z * Try: 2023-02-27T14:26:32.5947470Z Run with --stacktrace option to get the stack trace.

There are multiple build.gradle files on an Android Project.
Can you please tell in which build.gradle did you make the change? the outermost build.gradle file or the one inside the app folder
