Compile Godot for Android easily

#!/bin/sh -x

# This script compiles Android debug and release templates from a Godot Git clone.
# It needs to be run from a GNU/Linux system. The compilation process will automatically
# use all CPU threads available.
# You will need to install Android SDK (API 19) and NDK (latest, as of May 2016).

# Place this script at the root of your Godot Git clone.
# CC0 1.0 Universal

# Change those to the path of Android SDK and NDK
export ANDROID_HOME="/opt/android-sdk"
export ANDROID_NDK_ROOT="/opt/android-ndk"
