[Dan_Wroblewski]

It's May Day, which can only mean 1 thing ... the April challenge for SAP Build Apps is over ☹️

I hope you learned a lot, and had a little bit of fun along the way. Thanks for participating, and for the discussions as we together solved the puzzles, and thanks to my colleagues @eshrinivasan and @Rekha_DR for creating the last 2 challenges.

Everyone who completed at least one of the challenges will get a badge (similar to the one below). 

• Task 0: Set Up SAP Build Apps 
• Task 1: OData  
• Task 2: Formulas 
• Task 3: Theming, Styling and Layout Design           
• Task 4: Mobile device capabilities (this post) 

Some stats:

• 35,000 views of the challenge post (combined)

To keep track of the stats for the contest and to check whether people submitted the correct hash, we created an app, in SAP Build Apps, of course, which included:

• Mash-up of 2 APIs (circumventing CORS with destinations)
• Complex logic (including looping) to check all responses and then check hashes, all without JavaScript
• Formatted layout to easily show results
• Download of CSV for awarding badges

This is a classic case of a citizen developer being able to create for themselves an app to help with their day-to-day work. We created the basic app in about a week, and embellished it throughout April. I will try to write a separate blog about the app.

To be honest, I thought I was showing you guys a thing or two about SAP Builds Apps, but found I learned so much about SAP Build Apps during April, including:

• How to get around CORS with destination
• How to get around CORS with headers (including pre-flight conditions)
• The 3 ways to open a web page in an app
• How to get the current users email (app and mobile)
• How to get the user's current location
• How to embed a map or YouTube video in a web app
• How to work with audio
• How to create a custom menu
• The 4 ways for spacing out components
• The default Authorization header sent when creating REST data resources with destinations (that I didn't realize was ruining my API call)
• The 2 ways for navigating
• How to use containers for layout
• How to do looping in logic flows
• How to download a CSV file
• ... and a few more things

Thanks for participating – I hope you enjoyed it.

Till the next challenge 😺
