Question

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

A problem occurred          


        

Answer 1

In my limited experience with this question,I try to solve the problem use follow method:

1.Stay android build tools version the same with gradle version. For example:if you use the build tools version is 3.3.0,your gradle version must be 4.10.1.You can reference by the link https://developer.android.com/studio/releases/gradle-plugin and chagne your build tools & gradle version in your AS(File->Project Structure->Project)

2.If method1 don't work,you can custom your ndk toolchains version to solve the problem :like download ndk18 or ndk16 , setting the ndk path is your AS(File->Project Structure->SDK Location->Android NDK Location)

Answer 2

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

Answer 3

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

Answer 4

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.

Answer 5

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 three. Recompile, the problem is solved.

Answer 6

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!!
