Android SDK Manager Install Specific Version of NDK Bundle

As stated in the docs:

1. Use the sdkmanager tool to view versions of CMake and NDK packages that are available:

   sdkmanager --list
   

2. Pass the sdkmanager the strings for the packages that you want to install. For example, to install CMake and the NDK, use the following syntax:

   sdkmanager --install
     "ndk;major.minor.build"
     "cmake;major.minor.micro.build"
   

You can just download the android-NDK from their archives and integrate it with your android studio. You can download android-NDK 15 from the given URL:

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

To connect it with android studio, extract it into your drive and in android studio, go to File -> Project Structure -> SDK Location -> NDK Path (Put extracted path here)

If you're using Gradle plugin 3.5 or later (in beta at time of writing, but will be out soon), add the following to your build.gradle:

android {
    ndkVersion "19.2.5345600" // NDK r19c
}

If you're using an older Gradle plugin, you can download old NDK releases from https://developer.android.com/ndk/downloads/older_releases and point ndk.dir in your local.properties file at that instead.
