Error: No toolchains found in the NDK toolchains folder for ABI with prefix: llvm

by

I want to compile an open source android project (Netguard) using gradel (gradlew clean build) But I encountered this Error:

A problem occurred configuring project ':app'.
> Exception thrown while executing model rule: NdkComponentModelPlugin.Rules#cre
ateToolchains
   > No toolchains found in the NDK toolchains folder for ABI with prefix: llvm

I serached but didn’t find enything helping. Here is the main build.gradle:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle-experimental:0.6.0-alpha1'
    }
}
allprojects {
    repositories {
        jcenter()
    }
}
task clean(type: Delete) {
    delete rootProject.buildDir
}

And here is the build.gradle of the app project:

apply plugin: 'com.android.model.application'

model {
    android {
        compileSdkVersion = 23
        buildToolsVersion = "23.0.2"

        defaultConfig.with {
            applicationId = "eu.faircode.netguard"
            minSdkVersion.apiLevel = 21
            targetSdkVersion.apiLevel = 23
            versionCode = 2016011801
            versionName = "0.76"
            archivesBaseName = "NetGuard-v$versionName-$versionCode"
        }
    }
    android.ndk {
        moduleName = "netguard"
        toolchain = "clang"
        ldLibs.add("log")
    }
    android.sources {
        main {
            jni {
                source {
                    srcDir "src/main/jni/netguard"
                }
                exportedHeaders {
                }
            }
        }
    }
    android.buildTypes {
        release {
            minifyEnabled = true
            proguardFiles.add(file('proguard-rules.pro'))
            ndk.with {
                debuggable = true
            }
        }
    }
    android.buildTypes {
        debug {
            ndk.with {
                debuggable = true
            }
        }
    }
    android.productFlavors {
        create("all") {
        }
    }
}

dependencies {


compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:23.1.+'
    compile 'com.android.support:recyclerview-v7:23.1.+'
    compile 'com.squareup.picasso:picasso:2.5.+'
}

And I’m using gradle-2.9-all and android-ndk-r10e. I don’t know if I should mention anything else, so comment if you need any information.

Two years has passed, now if you come across here, you may possibly encounterd error message like this:

No toolchains found in the NDK toolchains folder for ABI with prefix mips64el-linux-android

or

No toolchains found in the NDK toolchains folder for ABI with prefix mipsel-linux-android

Latest NDK removed support for mips abi, and earler version of android gradle plugin still check for the existance of mips toolchain. see here for more info.

Solution: Upgrade android gradle plugin to 3.1 or newer.

e.g. Add following in the project level gradle [28-Sept-2018]

 classpath "com.android.tools.build:gradle:3.2.0"

Workaround: Create mipsel-linux-android folder structure to fool the tool. The easiest way would be to symbolic link to aarch64-linux-android-4.9.

# on Mac
cd  ~/Library/Android/sdk/ndk-bundle/toolchains
ln -s aarch64-linux-android-4.9 mips64el-linux-android
ln -s arm-linux-androideabi-4.9 mipsel-linux-android
