• Leave SDK Location ;) we can still select from Files> Project Structure> Modules> NDK Version

• Or, Simply Add

ndkVersion '22.0.7026061'

in build.gradle(app) like this

externalNativeBuild {
    ndkBuild {
        path file('src/main/jni/Android.mk')
    }
}

ndkVersion '22.0.7026061' // your desire version

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
}

• Extra Tips:--- you can set path variable here

• Still App not Building for NDK ??

  1. Close Android Studio.

  2. Delete .temp folder located C:\Users\%USERNAME%\AppData\Local\Android\Sdk (if exist)

  3. Delete Options Folder located in C:\Users\%USERNAME%\AppData\Roaming\Google\AndroidStudio4.1\

  4. Delete NDK or ndk-bundle folder located in your SDK directory... in my case D:\Android\SDK\ndk

  5. Now clean temps from SDK Manager > Optimize disk Space [don't worry it will not delete your essential files]

  6. Now, install your desire NDK version from SDK Manager
