#
# goal:
#   Develop kivy apps for android and quickly test directly in your
#   android devices with a simple and dynamically way, without to
#   create un apk package (that takes a lot lot time!)
#
#   How can i do this ? Transfering the files of your kivy project
#   directly to sdcard of the android device and start the app (Kivy
#   Launcher)
#
#   Have Fun!
#
#
#   Dependencies:
#   1. Have a usb cable connect in your computer and android device
#
#   2. Have android app (Kivy Launcher) installed in the android device
#   Link: https://play.google.com/store/apps/details?id=org.kivy.pygame
#
#   3. Have the android sdk uncompressed in your computer
#   Link: http://developer.android.com/sdk/index.html
#
#   4. Have buildozer installed:
#   Link: http://buildozer.readthedocs.org/en/latest/installation.html#targeting-android
#
#   Extra: (installation on ubuntu 13.10 or higher)
#       sudo pip install --upgrade cython
#       sudo dpkg --add-architecture i386
#       sudo apt-get update
#       sudo apt-get install build-essential ccache git libncurses5:i386 \
#                            libstdc++6:i386 python2.7 python2.7-dev \
#                            openjdk-7-jdk unzip zlib1g-dev zlib1g:i386
#
#   5. Define the ANDROID_SDK_PATH variable with the folder path of
#   your android sdk, (with you use buildozer your sdk will be here:
#   ~/.buildozer/android/platform/android-sdk..)
#
#   6. Define the KIVY_PROJECT_PATH variable with the folder path of
#   your kivy project
#
#   Thats All Folks!
#
#   Observation:
#   If you never heard about buildozer, research it, because it's really
#   worthwhile! it automates many processes to build the package creation
#   .apk, and just as I open (Kivy Launcher) at the end of the deployment,
#   it installs and opens your app Kivy you just package all in one command.
