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
Check this thread of three options for solving this kind of issue
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()
}
Happy Coding -:)
I fixed this Error by uninstalling the NDK in the SDK-Tools. So, if you don't need the NDK, uninstall it.
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.
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
After that it worked well for me.
Step-by-step:
1) Open the page with old NDK versions:
https://developer.android.com/ndk/downloads/older_releases
2) Agree the Terms:
3) Download the older version of NDK (for example 16b):
4) Open your toolchains directory.
5) Transfer files that you need from toolchains folder of downloaded zip-file to your toolchains folder:
6) Rebuild the Project:
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).
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.
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 .
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
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.
Open Android Studio, Go to Tools then Android and then SDK, uncheck NDK If you do not need this, and restart android studio.
[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.
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()
}
}
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".
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\toolchainsto\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.
I solved this question by unInstalled ndk, becasuse I dont't need it
Here is the fix.
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.
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
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 "
If you didn't find google() add it
For Android Studio 3.2.1 Update your
Gradle Version 4.6
Android plugin version 3.2.1
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)
it fixes!! Enjoy Coding
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:
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.
If you don't use the NDK, unset the environment variable ANDROID_NDK_HOME.
For me I think there might be some issue in installing android NDK from android studio. I was able to resolve this in following manner
Downloaded android ndk from
https://developer.android.com/ndk/downloads/index.html
and placed inside ndk-bundle (where your android sdk is installed ). For more info check this screens.
If you are using Ionic 3 Remove ndk from android studio sdk tools.
Find your own local android-SDK, if you download the relevant SDK of ndk, there will be a folder called "ndk-bundle"
There is a folder called "toolchains" inside.
We noticed that there are no mips64el related files inside.
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 3. Recompile, the problem is solved. Hope it helps you mate
Facing same issue.
I got success following ways.
Open your buldle.gradle file and upgrade the versions for following both classpath
classpath 'com.android.tools.build:gradle:3.2.1' classpath 'com.google.gms:google-services:4.2.0'
Then Sync and after get one dilaog for update Gradle version as well then click that link and wait for download all required updates(Hope internet available). After taking long time you got Success.
First, try updating the ndk version https://developer.android.com/ndk/downloads/
If that's not working then you can try the following:
Create a folder
Go to the Sdk\ndk-bundle\toolchains folder (in my case its C:\Users\USER\AppData\Local\Android\Sdk\ndk-bundle\toolchains; you can find yours under File->project structure->SDK location in you android studio) and create a folder with the name that's shown as missing in the error for eg: if the error is
Gradle sync failed: No toolchains found in the NDK toolchains folder for ABI with prefix: mipsel-linux-android
Then create a folder with name mipsel-linux-android
Include content Go to the Sdk\ndk-bundle\toolchains folder again and open any folder that's already in it. For example:Sdk\ndk-bundle\toolchains\aarch64-linux-android-4.9 (in mycase C:\Users\USER\AppData\Local\Android\Sdk\ndk-bundle\toolchains\aarch64-linux-android-4.9) copy the prebuilt folder in it to the folder we created in the last step
Run the project again and it will work
Hope it helps!!
Steps I have followed to fix the issue as follows,
Analyze -> Code Cleanup
File -> Project Structures -> Select project from the list and update the gradle version to latest.
Build -> Clean Project
Build -> Make Project
Now the issue related to the build may get reported like using compile instead of implementation etc.
Please fix those and hopefully it should fix the issue.
I fixed the issue by reinstalling the NDK.
