Configuring the Unity External Tools

Armed with all the stuff we need and the paths to the tools we installed, we can now go back into Unity. We need to tell Unity where to find all the Java and Android stuff. Note that if you skip this step, then Unity will prompt you for the folders when building the app:

1. On Windows, navigate to main menu and to Edit | Preferences, then select the External Tools tab on the left. On OS X it’s in Unity | Preferences.
2. In the Android SDK text slot, paste the path of your Android SDK.
3. In the Java JDK text slot, paste the path of your Java JDK.

The Unity Preferences with my SDK and JDK are shown here:
