Android 如何在Gradle中设置NDK lib路径?
我正在使用ebookdroid和MuPDF CPP文件开发PDF查看器应用程序。我在Gradle的NDK集成方面有很多问题。我已经看了很多答案,但都没有解决我的问题 Gradle向我发送了以下错误消息:Android 如何在Gradle中设置NDK lib路径?,android,c++,android-ndk,build.gradle,ndk-build,Android,C++,Android Ndk,Build.gradle,Ndk Build,我正在使用ebookdroid和MuPDF CPP文件开发PDF查看器应用程序。我在Gradle的NDK集成方面有很多问题。我已经看了很多答案,但都没有解决我的问题 Gradle向我发送了以下错误消息: Error:Execution failed for task ':app:compileDebugNdk'.

Consider using CMake or ndk-build integration with the stable Android Gradle plugin:
https://developer.android.com/studio/projects/add-native-code.html
or use the experimental plugin:

编辑build.gradle,添加defaultConfig.externalNativeBuild.ndkBuild,externalNativeBuild.ndkBuild和sourceSet.main.jni.srcDir选项。见下面的评论
android {
compileSdkVersion 22
buildToolsVersion "27.0.0"
defaultConfig {
minSdkVersion 18
targetSdkVersion 22
versionCode 1
versionName "1.0"
//add arguments passed to ndkBuild
externalNativeBuild {
ndkBuild {
arguments "NDK_TOOLCHAIN_VERSION=clang", "APP_SHORT_COMMANDS=true", "APP_ALLOW_MISSING_DEPS=true"
arguments "-j" + Runtime.runtime.availableProcessors()
cFlags "-fexceptions"
}
}
ndk {
abiFilters "armeabi-v7a"
}
}
//specify jni source file path
sourceSets.main {
java.srcDir "src"
res.srcDir "res"
jni.srcDir "jni"
}
buildTypes {
debug {
debuggable true
jniDebuggable true
}
}
//specify makefile / CMake file
externalNativeBuild {
ndkBuild {
path 'jni/Android.mk'
}
}
}
