    1
    D:FirstProject> calabash-android run your_file_name.apk
  7. If you will be automating the next sprint of this application then you have to re-build and re-sign application to create a new test server for each sprint using following command:
    1
    2
    D:FirstProject> calabash-android build your_file_name.apk
    D:FirstProject> calabash-android resign your_file_name.apk
