+# AndroidUnityPlugin
+
+What is this project?
+- This is a minimal Android library project that provides auth redirect handling back to the Unity Android app.
+
+How does it work?
+ - The AndroidManifest.xml file stored in Assets/Plugins/Android folder includes the definition of the AuthRedirectActivity
+   and adds an intent filter for the custom scheme used for the redirect.  When an intent is launched on Android with this custom
+   scheme, the AuthRedirectActivity is instantiated and the value of the uri is sent in a message back to a Unity game object.
+   Then, the main activity (UnityPlayerActivity) is launched and the AuthRedirectActivity is finished.
+
+How is it built?
+-  Run (double-click) the exportJar Gradle task, this will produce a new AndroidUnityPlugin.jar 
+   file and copy it into the the Assets/Plugins/Android folder in the Unity project.
+   This jar file and associated source code changes should be committed to your repo.
+
+Anything else?
+ - If a new version of Unity is released, it may be necessary to copy the classes.jar file from:
+   C:\Program Files\Unity 2018.1\Editor\Data\PlaybackEngines\AndroidPlayer\Variations\mono\Release\Classes\classes.jar
+   to:
+   \AndroidUnityPlugin\app\libs\classes.jar
+
