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

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.

Try to update the gradle tools. classpath 'com.android.tools.build:gradle:3.2.0-beta05'
use developer.android.com/ndk/downloads/older_releases and Android NDK, Revision 16b (December 2017) version to download required folders and fix the issue.

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

Check this thread of three options for solving this kind of issue


Tried with gradle 4.1, didn't work, but workaround (creation of folder mipsel-linux-android-dummy) worked. Thanks @lazybug.
@Girish upgrade Android Gradle Plugin in top level build.gradle file, something like com.android.tools.build:gradle:3.2.0-rc02, not Gradle version
The Workaround mentioned here is the correct one: # 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
On Windows: mklink /d mips64el-linux-android aarch64-linux-android-4.9 and mklink /d mipsel-linux-android arm-linux-androideabi-4.9 worked for me too.
You can check your native dependencies' SO files, if any. It may contain SO for MIPS that is not supported anymore, thus making NDK fail. Removing those SO files for MIPS is safe, and it will make error disappear.

I fixed this Error by uninstalling the NDK in the SDK-Tools. So, if you don't need the NDK, uninstall it.


What if I need NDK?
same here if we want NDK then what is the solution for it?
Its fixed if uninstall the NDK but if you required to use NDK then please Check this stackoverflow.com/a/51589406/6533853
To uninstall follow this stackoverflow.com/a/52207450/2768515
Its very strange despite the fact this is not the perfect answer to the problem , its still up voted .

For Android studio 3.2.1+

Upgrade your Gradle Plugin

classpath 'com.android.tools.build:gradle:3.2.1'

If you are now getting this error:

Could not find com.android.tools.build:gradle:3.2.1.

just add google() to your repositories, like this:

repositories {
    google()
    jcenter()
}

this worked for me . instead of this classpath 'com.android.tools.build:gradle:3.2.1'

I have faced the same problem while update Android studio from 2.0 to 2.1 in my Windows 8 machine.

I found a solution for that.Please use the following steps.

Download the android NDK for windows from https://developer.android.com/ndk/downloads/index.html. Extract the same and copy the "toolchain" folder from the bundle. Paste the folder under installed NDK folder under C:\android-sdk-win\ndk-bundle.[Installed the path may vary based on your installation] Restart android studio.

This is happening because Android studio won't gets full NDK update in the stable channel. If you are not using NDK for your project development you can simply remove the NDK folder from your SDK directory.


Works with Android Studio 3.2!
This also worked for me for fixing the error "Error : Android MIPS ToolChain directory "" does not exist" in Game Maker Studio 2 on a Mac. But I needed to get version 17c of the NDK from here : developer.android.com/ndk/downloads/older_releases (as per: reddit.com/r/gamemaker/comments/9m958a/…) Thank You @nithinjith ! ... still not building however, need to solve : Android NDK: Please fix the APP_ABI definition in /Users/../Library/Android/sdk/ndk-bundle/build/core/default-application.mk

Error message:

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

After fresh web installation of Android Studio with NDK, I imported an Android code sample that used NDK from GitHub and tried to compile it.

As a result had an Error:

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

Solution: for some reasons standard installation process on macOS had failed to install a complete set:

~/Library/Android/sdk/ndk-bundle had missed folder toolchains with all tools,

(it should be like this: ~/Library/Android/sdk/ndk-bundle/toolchains)

The solution was to download NDK separately, open it, copy folder toolchain and paste it to the folder:

~/Library/Android/sdk/ndk-bundle

in my case it's there but no file there with prefix aarch64-linux-android. Any suggestion !!
folder 'mips64el-linux-android-4.9' & 'mipsel-linux-android-4.9' are not available after ndk bundle 16, so i have to download and add these two folder in android sdk bundle inside toolchains folder hence issue solved, still didn't understand why this error?

Step-by-step:

1) Open the page with old NDK versions:

https://developer.android.com/ndk/downloads/older_releases

https://i.stack.imgur.com/gCmB0.png

2) Agree the Terms:

https://i.stack.imgur.com/z63Ft.png

3) Download the older version of NDK (for example 16b):

https://i.stack.imgur.com/Wqj1A.png

4) Open your toolchains directory.

5) Transfer files that you need from toolchains folder of downloaded zip-file to your toolchains folder:

https://i.stack.imgur.com/rS3aO.png

6) Rebuild the Project:

https://i.stack.imgur.com/qCHSD.png

UPD 30 Sep 2018: I used Android NDK Revision r16b for fix this error in my own case. So I present the example with this version. But it's better to use the Android NDK, Revision r17c (June 2018). It is the last one, supporting mips (reasonable reccomendation from Weekend's comment).


Instead of (for example 16b), it's better to clarify which NDK version is the last one supporting mips. via release note of Android NDK Revision r17c (June 2018): Support for ARMv5 (armeabi), MIPS, and MIPS64 has been removed. Attempting to build any of these ABIs will result in an error. It's 16b exactly.
@Weekend Thanks for your recommendation. I added it to my answer.
@vmarch Sorry but It's 16b exactly. r17c is the first version which removed the support for MIPS :)
@Oh, I read your previous comment so very quickly. That's why I missed the point. My apologize! But these files are still present in the Android NDK, Revision r17c (June 2018). And in version 18 they were finally removed. Just look into the archive. developer.android.com/ndk/downloads/…
@vmarch Well done! I didn't check r17c archive, just inferred the previous conclusion from release notes.

friederbluemle

Without downloading, copying, or symlinking anything, I was able to "fix" the error by simply creating an empty directory where the older version of the Android Gradle plugin expects the removed mips toolchain:

mkdir -p $ANDROID_HOME/ndk-bundle/toolchains/mips64el-linux-android/prebuilt/linux-x86_64

Obviously, $ANDROID_HOME points to the root of the Android SDK installation here. If you are using MacOS, replace linux-x86_64 with darwin-x86_64 in the command above. On Windows use windows-x86_64.


Worked like charm.
Depends on what your project refers to. Did not work for me, but is a nice and simple trick for some. I had to copy the real toolchain to get rid of the error.

I uninstalled the NDK since I didn't need it . Go to SDK manager on Android studio ( Tools -> Android -> SDK Manager ) . If NDK is installed . Just uncheck the box and click OK . The installed components will be deleted .


N
Nimantha

The best solution for this problem is:

Go to SDK Manager. Next choose SDK tools. Unselect NDK (side by side). Apply and OK.

In my case, this error occured when creating a new Android Studio (Android studio 3.2.1) Java Project with

classpath 'com.android.tools.build:gradle:2.0.0-beta6'

So I´ve downgraded to

       dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
      }

Not the best solution stay at an older version, but maybe it´s just a temporary bug in the beta as the NDK path in local.properties is still the same, but the IDE doesn´t complain anymore


I think this is a bug of outdated gradle plugin. Just update to the latest one. It helped to me (from 3.0 to 3.2.0-beta05 in my case)
I think It's upgraded not downgraded ... P

Android NDK 18.0* seems has an issue not creating all the files in folders after extraction. Due to it, your app compilation will fail which uses ndk builds.

Better is to use NDK 17.1* (https://developer.android.com/ndk/downloads/) etc version and you can extract or use the android studio extraction to ndk-bundle by default will work good.

Muhammad Bilal

Open Android Studio, Go to Tools then Android and then SDK, uncheck NDK If you do not need this, and restart android studio.


S
Sujith Royal

[https://github.com/tensorflow/tensorflow/tree/master/tensorflow/examples/android][1]

For people trying out this example and facing issues with latest NDK. Can follow this solution. In build.gradle change this

classpath 'com.android.tools.build:gradle:3.0.1'

To

classpath 'com.android.tools.build:gradle:3.1.2'

The reason is mips are deprecated in the latest ndk versions, Gradle version 3.1.2 will not have a compulsion for mips. It assumes the presence for these missing folders.

Yazdan Sharifi

The simple solution is download and extract the following file which contains mips64el-linux-android-4.9 and mipsel-linux-android-4.9 folders,to your toolchains folder inside sdk "android-sdk\ndk-bundle\toolchains".

Downlod this file and extraxt to toolchains foolder


Extract and then execute # 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

After looking around, the solution was to remove the NDK designation from my preferences.

Android Studio → Preferences → System Settings → Android SDK → SDK Tools → Unselect NDK → Apply button.

Project and Gradle compiled fine after that and I was able to move on with my project work.

As far as why this is happening, I do not know but for more info on NDK check out:

When compiling a project in android studio, I occasionally encounter:

Error: No toolchains found in the NDK toolchains folder for ABI with prefix: arm-linux-androideabi/llvm

This may be caused by updating related components. The solution is to Android studio ( Tools -> Android -> SDK Manager ) . Select the ndk item and delete it. If the program needs it, you can re-install it. This will ensure that the folder location is correct and there will be no such problem.


I deleted it. But when I compile my app, ndk is downloaded again. Did not work for me.

To resolve the issue just go to:

I resolved the same issue in linux(Ubuntu) machine using this technique.


On Catalina removed NDK and it worked.

Marcin Kunert

I've had a similar problem, but I wanted to use NDK version r9d due to project requirements.

In local.properties the path was set to ndk.dir=C\:\\Android\\ndk\\android-ndk-r9d but that lead to the problem:

No toolchains found in the NDK toolchains folder for ABI with prefix: [toolchain-name]

The solution was to:

Install the newest NDK using sdk manager Copy the missing toolchain [toolchain-name] from the new ndk to the old. In my case from sdk\ndk-bundle\toolchains to \ndk\android-ndk-r9d\toolchains Repeat the process till all the required toolchains are there

It looks to me that the copied toolchains are not used, but for some reason it is needed to for them be there.

In your project level Gradle file increase the dependencies classpath version low to high like

dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0'
    }

to change like

dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
    }

Solved it by adding google() dependency into both repositories in build.gradle(Project: ProjectName). then sync your project

buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.2'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

I solved this question by unInstalled ndk, becasuse I dont't need it


Y
Yipeng Zhang

I navigated to local.properties, and in there the

ndk.dir=/yo/path/for/NDK

line needs to be updated to where your ndk lies.

I was using Crystax NDK, and didn't realize the original Android NDK was still in use.

To fix it like i did

Android Studio File> project structure and go to project

change Gradle version to 4.6 & Android plugin version to 3.2.1

check screenshot

then clean project if you got this Error "Could not find aapt2-proto.jar"

go to build.gradle (project)

Try moving the google() method (.gradle file) to the top of its execution block the order of repositories it searches in that causes the issue.

for example, change this:

repositories {
  maven { url 'https://maven.fabric.io/public' }
  google()      <===  from here
  mavenCentral()
}

To this:

repositories {
  google()     <===  to here
  maven { url 'https://maven.fabric.io/public' }
  mavenCentral()
}

Make those changes in both "buildscript" and "allprojects "

check screenshot

If you didn't find google() add it

NOTE: This answer seems to be specific to: No toolchains found in the NDK toolchains folder for ABI with prefix: mips64el-linux-android, but it was linked here by:

* https://stackoverflow.com/questions/52193274/no-toolchains-found-in-the-ndk-toolchains-folder-for-abi-with-prefix-mips64el-l

From NDK r19b:

more ~/Android/Sdk/ndk-bundle/CHANGELOG.md

This version of the NDK is incompatible with the Android Gradle plugin version 3.0 or older. If you see an error like No toolchains found in the NDK toolchains folder for ABI with prefix: mips64el-linux-android, update your project file to [use plugin version 3.1 or newer]. You will also need to upgrade to Android Studio 3.1 or newer.

Navigate to C:\Users\lalit\AppData\Local\Android\Sdk\ndk-bundle\toolchains.

Now, find the folder name aarch64-linux-android-4.9 and rename it to mips64el-linux-android.

Re-run the android app.

Find your own local android-SDK, if you download the relevant SDK of ndk, there will be a folder called "ndk-bundle"

https://i.stack.imgur.com/v2uWJ.png

There is a folder called "toolchains" inside.

https://i.stack.imgur.com/NRfZv.png

We noticed that there are no mips64el related files inside.

https://i.stack.imgur.com/PqKuo.png

The solution is as follows:

Click here to download the NDK package separately through the browser. After unzipping, open the "toolchains" folder, compare it with the android-sdk->ndk-bundle->toolchains folder, find the missing folder, copy the past three. Recompile, the problem is solved.

Delete all your NDK in sdk tools.

The issue comes mostly when you are cloning a previous project specially from github. What you can do is

Change the classpath to

classpath 'com.android.tools.build:gradle:3.2.1'

in your project level gradle.

Then Change all the instances of compile with implementation except compileSdkVersion keep it as it is in your app level gradle. Instead of sync now click on make project(Ctrl+F9) Add google maven repositories if needed. Upgrade the gradle wrapper if needed.

(Android Studio IDE will ask / guide you with the same for steps 4 and 5)
