在Project的build.gradle脚本中定义一些全局变量
ext { compileSdkVersion = 21 buildToolsVersion = "24.0.1" minSdkVersion = 9 targetSdkVersion = 19 versionCode = 29 versionName = '3.1.0' targetCompatibility = 1.7 sourceCompatibility = 1.7 }
在Module的build.gradle脚本中调用
android { compileSdkVersion rootProject.ext.compileSdkVersion buildToolsVersion rootProject.ext.buildToolsVersion defaultConfig { minSdkVersion rootProject.ext.minSdkVersion targetSdkVersion rootProject.ext.targetSdkVersion" buildConfigField "String", "BUILD_DATE", ""${new Date().toLocaleString()}""; multiDexEnabled true } }
