title: Android SDK location in OSX - Has it been actually installed by Unity Hub?
body: <p>We are using Unity 2018.3.8f1.</p>
  
  <p>We have added Android Build Support from Unity Hub - Add Component:</p>

  <p>But if we go to Unity Preferences - External Tools, the Android SDK location is empty:</p>

  <p>I have not been able to find the location of the Android SDK folder anywhere. I'm wondering if the component installed by Unity Hub is something different to Android SDK. Maybe it must be installed separately from: <a href="https://developer.android.com/studio?pkg=tools#downloads" rel="nofollow noreferrer">https://developer.android.com/studio?pkg=tools#downloads</a>? </p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>So far I have installed "Command line tools only" from the previous link. Then, I have installed OpenSDK (Vistual Studio did it for me: it asked me to update and install it as one of the things to update). </p>
  
  <p>But when I opened tools/bin/sdkmanager, it said "Java is not installed". So I also installed Oracle Java SDK. Unfortunately tools/bin/sdkmanager returned errors after it. I applied a few workarounds I found by googling the errors. Still not luck.</p>
  
  <p>So I have moved to the <strong>easy way: installing the full version of Android Studio</strong>. If we choose custom, we'll see that Android SDK Platform is going to be installed:</p>

  <p><strong>So it is working, but</strong> I still have not idea of how many things I have <strong>duplicated</strong> on my system <strong>wasting space</strong>. I have:</p>
  
  <ul>
  <li>The Android component installed from Unity Hub</li>
  <li>Android Studio installed, which comes with the emulator and the IDE (I don't need them)</li>
  <li>OpenSDK (installed by Visual Studio)</li>
  <li>An embedded version of Java in Unity</li>
  <li>Oracle Java </li>
  </ul>
  
  <p>Are they all actually needed? I don't think so!</p>
