Android 11(R) 的 NDK 构建不受支持

Question

有没有为 android R 图像构建 C/C++ 项目？

我收到："C/C++ release|x86_64 : API codeName 'R' is not supported by NDK 'D:\Android_sdk\ndk.1.6352462" 错误。

这是项目结构：

我正在使用 Android Studio 4 RC1、Android R Preview 和 NDK此版本的版本 21.1。

这是 gradle 配置：

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion "android-R"
    buildToolsVersion "30.0.0 rc4"

    defaultConfig {
        applicationId "com.example.myapplication"
        minSdkVersion "R"
        targetSdkVersion "R"
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        externalNativeBuild {
            cmake {
                cppFlags "-std=c++17"
            }
        }
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    externalNativeBuild {
        cmake {
            path "src/main/cpp/CMakeLists.txt"
            version "3.10.2"
        }
    }
}

dependencies {
    implementation fileTree(dir: "libs", include: ["*.jar"])
    implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
    implementation 'androidx.core:core-ktx:1.2.0'
    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'

}

根据this comment，您需要从 Canary 频道安装更新的 NDK：

Android Studio menu,"settings > Appearance & Behavior > system Settings > Updates"
choose "Canary Channel"
The canary NDKs will be enabled for download:
"Tools > Sdk Manager > SDK Tools"
( assuming "Show Package Details" is enabled ) "NDK side by side"

或者您可以使用

从命令行安装它

sdkmanager --channel=3 --install 'ndk;21.1.6363665'
