Visual Studio in OSX: Installing Android SDK Platform-Tools v26.0.0 failed

Question

I'm trying to compile to Android using Unity3D. The normal procedure is installing Android Studio. However I want to use Visual Studio Community (Preferences -> SDK Locations -> Android) to avoid downloading Android Studio because I do not plan to use it:

The rest of components seems to be installed well. However the Android SDK Platform-Tools installation outputs the following error:

Installing Android SDK Platform-Tools v26.0.0 failed

Could not find a part of the path "/Users/username/Library/Developer/Xamarin/android-sdk-macosx/platform-tools/package.xml".

I have been able to install it after creating an empty folder named platform-tools manually. Unfortunately it seems it has not been installed correctly because the folder only contains one file named: package.xml of much less than 7 Mb. Unity also output the following error:

Android SDK is outdated

SDK Tools version 0.0.0 < 24.0.0.

Workarounds seem easy (both can be downloaded from here: https://developer.android.com/studio/index.html):

• Install Android Studio: it seems the easier and quick way, but >500Mb HardDisk space
• Install only command line tools: not so easy and quick

However I guess I'm very stubborn and curious: why could it be failing?

Hey mate for me it worked to create the missing folder manually.

So this folder:

/Users/username/Library/Developer/Xamarin/android-sdk-macosx/platform-tools/

Is actually missing so if you do this:

$ cd /Users/username/Library/Developer/Xamarin/android-sdk-macosx/
$ mkdir platform-tools

And try to run the installer from VS UI it should install the platform-tools package.

Complement from @benjamingranados:

Also check that the destiny folder in the "Locations" Tab is the same.
