Question & Answer :
I privation to compile an unfastened origin android task (Netguard) utilizing gradel (gradlew cleanable physique) However I encountered this Mistake:
A job occurred configuring task ':app'. > Objection thrown piece executing exemplary regulation: NdkComponentModelPlugin.Guidelines#cre ateToolchains > Nary toolchains recovered successful the NDK toolchains folder for ABI with prefix: llvm
I serached however didn’t discovery enything serving to. Present is the chief physique.gradle:
buildscript { repositories { jcenter() } dependencies { classpath 'com.android.instruments.physique:gradle-experimental:zero.6.zero-alpha1' } } allprojects { repositories { jcenter() } } project cleanable(kind: Delete) { delete rootProject.buildDir }
And present is the physique.gradle of the app task:
use plugin: 'com.android.exemplary.exertion' exemplary { android { compileSdkVersion = 23 buildToolsVersion = "23.zero.2" defaultConfig.with { applicationId = "eu.faircode.netguard" minSdkVersion.apiLevel = 21 targetSdkVersion.apiLevel = 23 versionCode = 2016011801 versionName = "zero.seventy six" archivesBaseName = "NetGuard-v$versionName-$versionCode" } } android.ndk { moduleName = "netguard" toolchain = "clang" ldLibs.adhd("log") } android.sources { chief { jni { origin { srcDir "src/chief/jni/netguard" } exportedHeaders { } } } } android.buildTypes { merchandise { minifyEnabled = actual proguardFiles.adhd(record('proguard-guidelines.professional')) ndk.with { debuggable = actual } } } android.buildTypes { debug { ndk.with { debuggable = actual } } } android.productFlavors { make("each") { } } } dependencies { compile fileTree(dir: 'libs', see: ['*.jar']) compile 'com.android.activity:appcompat-v7:23.1.+' compile 'com.android.activity:recyclerview-v7:23.1.+' compile 'com.squareup.picasso:picasso:2.5.+' }
And I’m utilizing gradle-2.9-each and android-ndk-r10e. I don’t cognize if I ought to notation thing other, truthful remark if you demand immoderate accusation.
