+This directoy contains Android Studio project files for building the NORM
+library for Android.
+
+REQUIREMENTS:
+
+Ninja is required in order to run the ant build for the java .jar file
+
+Download and install ndk and cmake using the SDK manager within Android Studio. To do this:
+
+    -> Tools -> SDK Manager -> System Settings -> Android SDK -> SDK Tools -> Select 'Show Package Details' at the bottom
+
+The latest compatible versions are ndk version 20.0.5594570 and cmake version 3.10.2.4988404
+
+* Important *
+  If you decide to install different version of the SDK Tools above, make sure to edit the path locations in the local.properties file
+
+TO BUILD:
+
+./gradlew build
+
+The lib/build/ directory will contain the binary libraries built.
+
+The "./gradlew clean" command can be used to delete the files built.
+
+This directory may also be opened as an Android Studio project and built from
+the IDE GUI.
+
+This will evolve as we update NORM and associated projects to the newer Android
+Studio tool chain.
+
+USAGE:
+
+Copy the .aar file into your ${project.rootDir}/app/libs/ folder
+
+Within your app level build.gradle include the following two tasks before your dependencies section:
+
+```
+task extractSo(type: Copy) {
+    println 'Extracting *.so file(s)....'
+
+    from zipTree("${project.rootDir}/app/libs/lib-release_-release.aar")
+    into "${project.rootDir}/app/src/main/jniLibs"
+    include "jni/**/*.so"
+
+    eachFile {
+        def segments = it.getRelativePath().getSegments() as List
+        println segments
+        it.setPath(segments.tail().join("/"))
+        return it
+    }
+    includeEmptyDirs = false
+}
+
+task extractJar(type: Copy, dependsOn: extractSo) {
+    println 'Extracting *.jar file(s)....'
+
+    from zipTree("${project.rootDir}/app/libs/lib-release_-release.aar")
+    into "${project.rootDir}/app/libs/"
+    include "norm-*.jar"
+}
