MacBook Pro M1运行安卓项目报Unknown host CPU architecture: arm64 NDK错误如何解决

问题背景 #

原有安卓项目在Windows系统运行正常，更换为MacBook Pro M1设备后打开项目无法正常运行，首次出现如下报错：

Execution failed for task ':app:kaptDevDebugKotlin'. > A failure occurred while executing org.jetbrains.kotlin.gradle.internal.KaptExecution > java.lang.reflect.InvocationTargetException (no error message)

该报错由Room数据库组件不兼容M1架构导致，临时修复方案如下：

• 在Room依赖声明前添加sqlite-jdbc适配库：kapt "org.xerial:sqlite-jdbc:3.34.0"
• 将项目的JDK位置从默认JRE修改为完整JDK

完整Room依赖配置参考：

//Room components
kapt "org.xerial:sqlite-jdbc:3.34.0"
implementation "androidx.room:room-ktx:$rootProject.roomVersion"
kapt "androidx.room:room-compiler:$rootProject.roomVersion"
androidTestImplementation "androidx.room:room-testing:$rootProject.roomVersion"

二次报错问题 #

完成上述修改后出现Unknown host CPU architecture: arm64报错，涉及的项目配置如下：

SDK模块Gradle配置 #

android {
    externalNativeBuild {
        ndkBuild {
           path 'Android.mk'
        }
    }
    ndkVersion '21.4.7075529'
}

App模块Gradle配置 #

externalNativeBuild {
        cmake {
            path "src/main/cpp/CMakeLists.txt"
            version "3.18.1"
            //version "3.10.2"
        }
    }

完整报错信息：

[CXX1405] error when building with ndkBuild using /Users/mac/Desktop/Consumer-Android/ime/dictionaries/jnidictionaryv2/Android.mk: Build command failed. Error while executing process /Users/mac/Library/Android/sdk/ndk/21.4.7075529/ndk-build with arguments {NDK_PROJECT_PATH=null APP_BUILD_SCRIPT=/Users/mac/Desktop/Consumer-Android/ime/dictionaries/jnidictionaryv2/Android.mk APP_ABI=arm64-v8a NDK_ALL_ABIS=arm64-v8a NDK_DEBUG=1 APP_PLATFORM=android-21 NDK_OUT=/Users/mac/Desktop/Consumer-Android/ime/dictionaries/jnidictionaryv2/build/intermediates/cxx/Debug/4k4s2lc6/obj NDK_LIBS_OUT=/Users/mac/Desktop/Consumer-Android/ime/dictionaries/jnidictionaryv2/build/intermediates/cxx/Debug/4k4s2lc6/lib APP_SHORT_COMMANDS=false LOCAL_SHORT_COMMANDS=false -B -n} ERROR: Unknown host CPU architecture: arm64

当前临时方案为注释path 'Android.mk'配置即可正常运行，需求为保留该配置的前提下解决NDK兼容问题。

可行解决方案 #

• 方案1：升级Room版本到2.3.0-alpha01 / 2.4.0-alpha03及以上版本，该版本已原生适配M1芯片架构，无需额外添加sqlite-jdbc适配依赖
• 方案2：直接升级NDK版本到ndkVersion "24.0.8215888"，无需修改其他构建脚本即可直接解决arm64架构兼容问题
