Android AAR 中的 Studio 4.2.2 本机依赖项 buildFeatures.prefab=true - 缺少参数 "PACKAGE_PATH"

Question

Android Studio 4.2.2

为预制 AAR 共享库添加构建功能预制 Android。mk/CMake 构建：

https://developer.android.com/studio/build/native-dependencies?buildsystem=cmake&agpversion=4.1

完全遵循 Android Studio 4.1+ 的文档并使用构建功能

android {
        buildToolsVersion '30.0.3'
        ndkVersion '22.1.7171670'
    
        buildFeatures {
            prefab true
        }
}

问题：

Error while executing java process with main class com.google.prefab.cli.AppKt with arguments {--build-system ndk-build --platform android --abi armeabi-v7a --os-version 21 --stl c++_static --ndk-version 22 --output /Users/~var/Documents/project/.cxx/ndkBuild/debug/prefab/armeabi-v7a/prefab}

Usage: prefab [OPTIONS] [PACKAGE_PATH]...

Error: Missing argument "PACKAGE_PATH".

错误：缺少参数“PACKAGE_PATH”。

Answer 1

设置时：

buildFeatures {
        prefab true
    }

然后您必须 Link 在设置该命令后到现有的预制发布模块，否则会发生此错误

如果你根本不使用预制件删除这一行，它会编译

或者可以通过 Android.mk 或 CMakeLists

Link 到活动预制件

Android.mk

include $(CLEAR_VARS)
$(call import-add-path, $(LOCAL_PATH)/modulePath)
$(call import-add-path, /../../anotherModulePath)
# If you don't need your project to build with NDKs older than r21, you can omit
# this block.
ifneq ($(call ndk-major-at-least,21),true)
    $(call import-add-path,$(NDK_GRADLE_INJECTED_IMPORT_PATH))
Endif
# the linked prefab published module project location 
$(call import-module, openFrameworksAndroid)

如果您需要使用 Prefab 类型构建模块库，请设置 gradle 设置 buildFeatures.prefabPublishing true 并配置这些额外的命令

// Enable generation of Prefab packages and include them in the library's AAR.
buildFeatures {
    prefabPublishing true
}

// Include the "mylibrary" module from the native build system in the AAR,
// and export the headers in src/main/cpp/include to its consumers
prefab {
    openFrameworksAndroid {
        //headers "src/main/cpp/include"
    }
}

// Avoid packing the unnecessary libraries into final AAR. For details
// refer to https://issuetracker.google.com/issues/168777344#comment5
// Note that if your AAR also contains Java/Kotlin APIs, you should not
// exclude libraries that are used by those APIs.
packagingOptions {
    exclude("**/libopenFrameworksAndroid.so")
    exclude("**/classes.jar")
}
