Android App 在模拟器中运行良好，但无法在真实设备中安装

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并运行良好，但尝试在真实设备中安装时出现 Cmake 错误。 错误信息：

任务 :engine:configureCMakeDebug[arm64-v8a] FAILED 任务 ':engine:configureCMakeDebug[arm64-v8a]' 执行失败。 [CXX1410] D:\KAM\code\AET\AET\engine.cxx\Debug\3p465u2i\arm64-v8a\android_gradle_build.json debug|arm64-v8a：预期buildTargetsCommandComponents 或 ncnn-release-arm64-v8a.buildCommandComponents 存在

CMakeList.txt：

}


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

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

不同的 abi 应该至少有 4 个文件夹

x86 - x64 -- arm64/v7a -- arm64/v8

如果那里不存在

将此应用于您的 build.gradle

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