not finding android sdk (Unity)

android unity3d

I have same problem.

I fixed by android sdk tool version downgrade.

The steps.

Delete android sdk "tools" folder: [Your Android SDK root]/tools -> tools
Download SDK Tools:http://dl-ssl.google.com/android/repository/tools_r25.2.5-windows.zip
Extract that to Android SDK root
Build your project

android unity3d

The issue is due to incompatibility of unity with latest Android build tools.For MacOS here's a one liner that will get it working for you:

cd $ANDROID_HOME; rm -rf tools; wget http://dl-ssl.google.com/android/repository/tools_r25.2.5-ma‌cosx.zip; unzip tools_r25.2.5-macosx.zip

android unity3d

2- scroll down to the bottom of that page

3- download last version of tools for your OS (for example tools_r25.2.3-windows.zip)

4- Unzip it

5- Delete folder tools from previous Android Sdk folder

6- Copy new folder tools to Android SDK Folder like this image:
