Android错误“预期buildtargetScommandComponents [...]＆quot;

Question

我正在开发一个用于简单面部识别的Android应用程序。

• 我的应用程序在模拟器中构建和运行良好，
• 但是应用程序无法在真实设备中安装，
• 并且我们会因cmake相关任务而获得gradle错误，并带有错误：

任务：引擎：configurecmakedebug [arm64-v8a]失败 执行失败的任务'：Engine：configurecmakedebug [ARM64-V8A]'。 [CXX1410] D：\ kam \ code \ aet \ aet \ aet \ Engine.cxx \ debug \ 3p465u2i \ arm64-v8a \ android_gradle_build.json ncnn-release-arm64-v8a.buildCommandComponents存在

cmakelist.txt：

cmake_minimum_required(VERSION 3.4.1)

set(CMAKE_BUILD_TYPE "release")
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${PROJECT_SOURCE_DIR}/../../../distribution/${ANDROID_ABI})

    androidTestImplementation 'androidx.test.ext:junit:1.1.2'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'
}


I try to find the reason but no luck. So far find only [this][1].
Any help or resource will be great for me. Thanks

Answer 1

我刚刚遇到了类似的“预期buildtargetScommandComponents ...”错误日志。

与其他时候一样，删除构建目录并重新启动IDE解决了问题。

Answer 2

首先重建您的应用程序，然后检查此位置

PROJECT PATH...\app\build\intermediates\cmake\debug\obj

至少应有4个文件夹，用于不同的ABI的

X86- X64 -ARM64/V7A -ARM64/V8

如果不存在，

则将其应用于您的build.gradle.gradle

abiFilters 'x86', 'x86_64', 'armeabi', 'armeabi-v7a', 'arm64-v8a'
