Android Studio NDK could not start mips64el-linux-android-strip

If you’re using Android Studio to build C++ application with NDK you might encounter following error during build:

org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:transformNativeLibsWithStripDebugSymbolForDebug'.
...
Caused by: java.io.IOException: Cannot run program ".../Android/Sdk/ndk-bundle/toolchains/mips64el-linux-android-4.9/prebuilt/linux-x86_64/bin/mips64el-linux-android-strip": 
error=2, No such file or directory

The problem is caused by the upgrade of NDK in Android Studio to NDK v17. This version has a different structure of tools. It’s not compatible with Android Experimental Plugin v0.11.

The directory which should contain binary of tools contains just file NOTICE-MIPS64:

This mips64el-linux-android-4.9 directory exists to make the NDK compatible with the Android
SDK's Gradle plugin, version 3.0.1 and earlier, which expects the NDK
to have a MIPS64 toolchain directory.

The solution is to download NDK v16 from NDK older releases. Extract it and replace former ndk-bundle directory.

Commands for macOS or Linux users:

cd ~/Android/Sdk
unzip ~/Downloads/android-ndk-r16b-linux-x86_64.zip
mv ndk-bundle ndk-bundle-v17
mv android-ndk-r16b ndk-bundle

If you’re Windows user the location of NDK is typically in your profile AppData\Local\Android. Do not forget to unblock the ZIP after downloading (right click, Properties, Unblock, Ok)

Commands for Windows users:

cd ~\AppData\Local\Android\Sdk
unzip ~\Downloads\android-ndk-r16b-windows-x86_64.zip
mv ndk-bundle ndk-bundle-v17
mv android-ndk-r16b ndk-bundle

Start Android Studio. It should prompt you to update NDK. Do not confirm this request, it will replace NDK with v17. You should see the following screen in SDK Manager:
