Shell script to check for Android SDK version.
#!/bin/bash
# Bash script to assert that the current version of the SDK is at least the
# specified version. Prints 'true' to standard out if it's the right version,
# 'false' if it's not.
#
# Typically used like this, in your Makefile:
#
# ifneq ($(shell $(LOCAL_PATH)/assert_sdk_version.sh "r16"),true)
# $(error SDK version r16 or greater required)
# endif
#
# See https://gist.github.com/1961404 for asserting NDK version.
#
# Copyright 2012, Lookout, Inc. <jtjerno@mylookout.com>
# Converts 'r16' into '16'.
