2) Save AndroidDemoProject.apk file to the folder

3) Generate a Cucumber skeleton :
  In CMD prompt, go to the  "AndroidDemoProject" folder and Run the command C:\AndroidDemoProject\calabash-android gen
It will create a Cucumber skeleton in the current folder like this:

features
|_support
| |_app_installation_hooks.rb
| |_app_life_cycle_hooks.rb
| |_env.rb
|_step_definitions
| |_calabash_steps.rb
|_my_first.feature 

4) Open the file my_first.feature and enter the following text:

 Feature: Demo feature
 Scenario: I can start my app
    And I wait for "Hello World, AndroidDemoProject" to appear

    And take picture

5) Finally - Execute Test code:
  From CMD prompt C:\AndroidDemoProject\calabash-android run AndroidDemoProject.apk

*** In Case you get the following Error****

C:\AndroidDemoProject>calabash-android run AndroidDemoProject.apk
No test server found for this combination of app and calabash version. Recreating test server.
C:/Ruby193/lib/ruby/gems/1.9.1/gems/calabash-android-0.4.4/lib/calabash-android/
helpers.rb:145:in `block (2 levels) in fingerprint_from_apk': No RSA file found in META-INF. Cannot proceed. (RuntimeError)

This is because the .apk should be signed

Follow the Steps below to overcome the above Error

• Copy AndroidDemoProject.apk file to this folder - C:\Users\<UserName>\.android>
• In CMD prompt, go to this location: C:\Users\<username>\.android
• Type > jarsigner -keystore debug.keystore -storepass android -keypass android AndroidDemoProject.apk androiddebugkey > click enter. 
• We are done with the signing part
•  Copy AndroidDemoProject.apk and replace file in folder AndroidDemoProject 

Repeat Step 5 above - The Test should be Successful
