1.在 gradle/libs.versions.toml 文件中定义：

[versions]
compileSdk = "34"
minSdk = "21"
targetSdk = "34"

2. 在 build.gradle 中使用：

android {
    compileSdkVersion libs.versions.compileSdk.get().toInteger()
    
    defaultConfig {
        minSdkVersion libs.versions.minSdk.get().toInteger()
        targetSdkVersion libs.versions.targetSdk.get().toInteger()
    }
}
