My NDK project fails to compile with a CPU architecture-related issue

Question

Can someone explain why I get this errors please?

Build command failed.

I leave here a screenshot of my android studio if can be helpful

Answer 1

最有可能的是，您安装了NDK r17，不再支持 armeabi 。您的gradle插件不知道最近的更改。您必须升级：在 build.gradle 中，您应该

buildscript { dependencies {
    classpath 'com.android.tools.build:gradle:3.1.2'
} }

并在 gradle / wrapper / gradle-wrapper.properties

distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip

但即使升级后，您的 build.gradle 也很可能缺少 abiFilters 语句，因此您的项目构建速度较慢且APK大于必要。

您可能只需要在APK中使用ABI，

android { defaultConfig { ndk {
    abiFilters 'armeabi-v7a'
} } }

我最近收到此错误-原因仍然是个谜。我重新安装了所有内容，但无法将我的项目清理。

最后，我手动删除了app/build和app/.externalNativeBuild文件夹，并重新构建了项目，然后我又可以再次运行Clean了，而且没有错误。
