Gradle7、AGP7升级适配

• 升级Gradle可以用上最新的编译优化特性
• Compose的正式版本是从AGP4.2.0开始支持的
• Android Studio Flamingo版本支持

AGP升级

build.gradle

 classpath "com.android.tools.build:gradle:7.2.2"

Gradle 升级

gradle-wrapper.properties

distributionUrl=https\://services.gradle.org/distributions/gradle-7.3.3-bin.zip

so文件压缩声明

Android Gradle plugin >= 3.6.0 会默认关闭so文件的压缩

AndroidManifest.xml
<application
    android:extractNativeLibs="true"
...
>

允许使用http仓库

项目构建时报错：Using insecure protocols with repositories, without explicit opt-in, is unsupported.
Switch Maven repository ‘maven(XXX)’ to redirect to a secure protocol (like HTTPS) or allow insecure protocols.

maven {
    
    
    allowInsecureProtocol = true
    url 'http://xxx/maven2/'
}

尽量用https的

BuildConfig

BuildConfig.APPLICATION_ID 改为 BuildConfig.BROWSER_APPLICATION_ID

BuildConfig.VERSION_CODE 改为 BuildConfig.BROWSER_VERSION_CODE

该字段已废弃

mapping文件丢失

旧：/apps/xx/xx/build/outputs/mapping/arm/release/mapping.txt
新：/apps/xx/xx/build/outputs/mapping/armRelease/mapping.txt

混淆问题

AGP7.2之后minifyEnabled=true 在debuggable=true的变体不生效

R8问题

AGP7之后没有android.enableR8 配置，无法关闭r8

新增Build Analyzer

可以方便查看编译时各个Task耗时
