Rhodes on android

Download android 

After installing the android sdk and ndk in your machine, add the path within the rhobuild.yml file (rhobuild,yml resides within the rhodes gem, inside the ruby, which you are using. Something like this, if you are using the ruby from the Motorola Rhomobile Suite: C:\MotorolaRhoMobileSuite2.0.5\ruby\lib\ruby\gems\1.9.1\gems\rhodes-3.4.2\rhobuild.yml))

A typical entry looks like this: remember to maintain the indentations in the yml file.
    android-ndk: D:/Android/android-ndk-r8b-windows/android-ndk-r8b
    java: C:/Program Files (x86)/Java/jdk1.6.0/bin
    android: D:/Android/adt-bundle-windows-x86_64/adt-bundle-windows/sdk

Android 4.2 runs with rhodes 3.3.2(without license)

For any other rhodes version(below 3.3.2), you will wither get an error like the following or for rhodes(above 3.3.2) it will require a license from Motorola.

Getting such an output while executing the below command for android 4.2.
ruby 1.9.3
rhodes 3.2.2( rhodes 3.3.3 or above requires a license, hence not used)
