我的NDK项目由于CPU架构相关的问题而无法编译

Question

有人能解释一下为什么我会出现这些错误吗？

Build command failed.

很有可能，您已经安装了NDK r17，它不再支持armeabi了。你的gradle插件不知道这个最近的变化。您必须升级：在build.gradle中，您应该有

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

和在gradle/wrapper/gradle-wrapper.properties中

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

但是即使在升级之后，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，APK也比所需的大。

您可能只需要APK中的ABI,

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