5. How Do We Solve This Problem?
Background
Here is the world map from where United States gets oil from
To manage the daily workovers by large numbers of workers we need some from of software that can help us update information in the presence and absence of internet
How Do We Solve This Problem?

6. Previous Work
Landmark, Halliburton’s technology solutions provider, created an iOS application in the year 2014
OpenWells Application is a mobile application used by Halliburton workers that provide a way to manage daily information of Oil Wells
Operations can be logged upon daily, monthly as well as yearly basis
Landmark’s OpenWells iOS app provides a quick and easy data entry for Workover operations in a connected or disconnected world.
The app can be downloaded from the App Store: Halliburton's App Link
Major Limitation: Application is only available on iPad and related iOS devices

7. Cross-platform Features
Our task is to convert this iOS application into Xamarin Cross platform application
We will be using Xamarin Forms to implement a cross platform mobile application
This application is targeted to run on all major mobile devices

8. Xamarin Forms
Xamarin is a mobile application development tools owned by Microsoft which primarily uses C# as a code behind language
Subsequently, we can use Xamarin as an extended feature to Microsoft Visual Studio while creating apps on a Windows Machine
Furthermore, we can use Xamarin Studio to enjoy similar benefits on a Mac OS X machine

9. Xamarin Forms Features
In order to create a cross platform application, Xamarin provides a UI toolkit named as Xamarin.Forms
Xamarin.Forms allows you to write user interfaces using XAML, the eXtensible Application Markup Language
Since Xamarin.Forms is suitable for popular MVVM (Model-View- ViewModel) application architecture, we can programmatically create a wide variety of new user interfaces with existing models
Xamarin also support various Web Services via web APIs

10. Roadblocks
The most noteworthy roadblock that we encountered while working with Xamarin is while installing Xamarin on Windows 10
The JDK version which gets installed with Xamarin was incompatible android SDK which comes along with the installation package
You have to manually install a lot of APIs within android SDK in order to get the Android Emulator working
You have manually install Visual Studio Cross Platform features even after installing Xamarin
We then switched to Xamarin Studio on Mac OS X, where again we had to manually match the JDK and SDK version, since the default combination did not work.

11. Requirements analysis
Business requirements
Functional/technical requirements
Hardware/software requirements

12. Business Requirements
Develop an application that can manage oil well workover tasks and functions similarly to the Landmark OpenWells iOS application for the Android platform
User should be able to input daily oil well workover task information
User should be able to enter data in a connected or disconnected environment
Application should sync with the EDM database
User should be able to view data entered in the past or obtained from EDM database
User information should be tied to the submitted data

13. Functional/Technical Requirements
Develop an application that can manage oil well workover tasks and functions similarly to the Landmark OpenWells iOS application for the Android platform
Application should be developed in Xamarin with cross platform capabilities for both iOS and Android using the Xamarin.Forms library
User should be able to input daily oil well workover task information
Application should allow numerical data entry with value limits
Application should allow textual data entry for both data and comment fields
Application should allow user to input information via radio buttons
Application should allow user to delete entered data
Application should allow user to attach a media file or document

14. Functional/Technical Requirements
User should be able to enter data in a connected or disconnected environment
Application should be able to detect if it is in a connected or disconnected environment
Application should save and store data locally on device in both connected and disconnected environments
Application should sync with the EDM database
Application should send stored data to EDM database if it is in a connected environment
Application should receive data from the EDM database if it is in a connected environment
Application should allow manual syncing of data to the EDM database with a “Sync” button

15. Functional/Technical Requirements
User should be able to view data entered in the past or obtained from EDM database
User should be able to generate a PDF report with details of daily tasks
User should be able to view past data within the application
Application should display views of the data filtered by “All”, “Year”, “Month”, and “Day”
Application should display Well Bore schematic data obtained from the EDM database
Application should display a map of the current area via device GPS
User information should be tied to the submitted data
User information should be tied to the device settings
Application should identify the user for a specific device the first time a well is downloaded

16. Hardware/Software Requirements
Windows computer with Xamarin Open Source installed
Android device with GPS
Apple computer capable of viewing OpenWells application source code
iPad tablet with GPS capable of running the Landmark OpenWells application
Software:
Xamarin Open Source
XCode
Visual Studios (compatible with Xamarin Open Source)

23. Database Info
Landmark Engineer’s Data Model (EDM) is the corporate database
The OpenWells application is able to sync with the EDM database
Realm Mobile Database will be used to generate a mobile database on each android device
The Realm Database will communicate with EDM corporate database via the AutoSync API
