+# This script downloads the GVR SDK, explodes the AAR files, and creates zip packages than
+# can be used by the mode to generate the required libraries to build a cardboard sketch.
+# The steps in the AAR to ZIP conversion were based on this blogpost:
+# https://commonsware.com/blog/2014/07/03/consuming-aars-eclipse.html
+
+# Usage:
+# call with the version number of the GVR SDK package to download and extract, i.e.:
+# ./gvrsdk-update.sh 1.0.1
+
+ver=$1
+sdk=v$1
+
+mkdir ../libraries/cardboard/gvrsdk/$ver
+
+wget https://github.com/googlevr/gvr-android-sdk/archive/$sdk.zip
+
+unzip $sdk.zip
+
+#Explode the aars and create the corresponding zip packages to use in the mode
+unzip gvr-android-sdk-$ver/libraries/base/base.aar -d base.aar
+unzip gvr-android-sdk-$ver/libraries/common/common.aar -d common.aar
