  The following setup for AR is done after making an export from Unity.
+
+
+<b>Warning: The `XR Plugin Management` package version `4.3.1 - 4.3.3` has bug that breaks Android exports. </b>
+
+- The bug accidentally deletes your AndroidManifest.xml file after each build, resulting in a broken export.  
+Switch to version `4.2.2` or `4.4` to avoid this.
