最近不少朋友问我关于 android compileSdkVersion
SDK Manager
配置问题。
今天就来讲下,相关的配置属性有 compileSdkVersion
buildToolsVersion

minSdkVersion
。

gradle 包管理
Gradle 是一个基于 JVM 的构建工具,用的 Groovy 脚本进行配置。
https://gradle.org/
打印 gradle 配置
我们先来看下这个默认配置值
- 文件 android/app/build.gradle
// 打印配置
println "gradle.gradleVersion: $gradle.gradleVersion"
println "android.buildToolsVersion: $android.buildToolsVersion"
println "flutter.compileSdkVersion: $flutter.compileSdkVersion"
println "flutter.targetSdkVersion: $flutter.targetSdkVersion"
println "flutter.minSdkVersion: $flutter.minSdkVersion"
println "flutter.ndkVersion: $flutter.ndkVersion"
android {
...
- 双击 gradle 面板 tasks 输出
gradle.gradleVersion: 7.4
android.buildToolsVersion: 30.0.3
flutter.compileSdkVersion: 31
flutter.targetSdkVersion: 31
flutter.minSdkVersion: 16
flutter.ndkVersion: 21.1.6352462

名词解释
compileSdkVersion
指使用哪个 api level SDK 来编译你的代码minSdkVersion
最低的可运行 api level 版本- 你用的三方库有自己的 minSdkVersion, lint 会在编译的时候检查是否满足
targetSdkVersion
目标设备最小兼容 api level 设备,前提是你在这个设备上充分测试可以运行- 如 22,表示运行在 android 5.1 以上的设备, 没有动态授权特性
- 如 23,表示运行在 android 6.0 以上的设备,有动态授权特性
buildToolsVersion
构建工具版本版本关系
minSdkVersion <= targetSdkVersion <= compileSdkVersion
配置参考
def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
localPropertiesFile.withReader('UTF-8') { reader ->
localProperties.load(reader)
}
}
def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}
def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
flutterVersionCode = '1'
}
def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
flutterVersionName = '1.0'
}
// 定义属性读取对象,读取 android/key.properties
def keystoreProperties = new Properties()
def keystorePropertiesFile = rootProject.file('key.properties')
if (keystorePropertiesFile.exists()) {
keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
}
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
// 打印配置
