Survived week 1: Introduction to Mobile Solution Development

In case you do not know: offers a MOOC focused on mobility: Introduction to Mobile Solution Development

After week 1, my overall impression is that the course content is delivered with a broad audience in mind, touching many areas at once. The focus is of course SAP technology, so do not expect a course that will teach you jQuery Mobile. The offering is a good motivation to learn SAP mobility, SAP’s take on it and SAP’s approach to develop a mobile application. Finally a reason to refresh my oData knowledge.

My overall goal is to stay with the course and to pass the final exam. How I do not know, as the only time free I currently have is during commute from and to work. I am not in the course to get the Record of Achievement, but to have a good motivation to learn SAP’s view on mobility.

My Experience

I almost forgot that the course already started, I accessed the content mid last-week. For those trying to access the course behind a corporate proxy: the videos are hosted on vimeo, I guess for 99% of those this means: no streaming. I thought about downloading the material in the background, but after a few tries I found out that this will stay a dream, at least for the videos.

Why? Download is slow. I have 10 Mbit down at home, and even when downloading it at night, speed is really disappointing.


At work it is even worse, I think the corporate infrastructure is set up to not prioritize mp4 files (that’s OK, btw). While updating my Android SDK, I got this download speed reported:


Wikipedia tells me that 1 KiB/s == 1024 bytes == KB. In that case we have once 133 KB vs. 1259KB. No comment.

The videos sum up for almost 700MB for week 1. I thought in downloading them at once, but given the download speed I guess I will have to do this course without videos at all and rely on the PDFs. The session PDFs contain the valuable theoretical information, the speaker (Craig Haworth) isn’t adding something that is NOT in the PDFs. [1]. A workaround is the transcript PDF. It contains all the necessary information to understand what the video shows. It looks like the text is auto-generated, if not: it’s SCN, not SEN.


Learning by doing

There is a list of software provided that you’ll have to download and configure on your own. No ISO image made available with everything pre-installed. Sad, but doable [2]. A “big” problem is that the examples are not made with people that use a corporate proxy. It’s up to you to find out how to authenticate oData SAP UI calls against the used SAP system in such a way that it works.

For instance, in unit 4, the oData example: "$format=json", function (data) …

This won’t work as it won’t authenticate you against the Gateway service. To know how to authenticate, take a look into unit 5, W1U5_MyFirstIntegratedWebApp{ requestUri: "$format=json",
 user: "user",
 password: "password"}

If you now think: that’s it, problem solved: wait until you run the code in Cordova:


For the HTTP request to work in Cordova, it needs to be:{ requestUri: "$format=json&sap-user=<user>&sap-password=<password>"}

The workload of week 1 was OK. Getting the examples running took up most of the time, but once this was solved, it was no problem at all to get through the content. And I do most of it on my commute. If only I could download the videos …

What else?

Installing Cordova using NPM

In case you want to do this while being behind a proxy, set the proxy.

npm config set proxy http://<user>:<password>@proxyserver:8080

Although that doesn’t mean it works, especially when the proxy is blocking on a given URL schema. Set up your environment at home, with no proxy at all between you and the internet.

Setup Cordova

You should really go through the Cordova cli documentation. After going through the Cordova introduction example, at least the emulator should start and show the example app.


Make sure – when under Windows – that the path to your project folder for hybrid apps does not contain a space. When you think using week 1 as a folder name is a good choice, be aware that Cordova disagrees with you. Name the folder week1, without space.

What else?

A mobile project can contain quite a lot of files:


This screams for a SSD!

      Hi Tobias,

      Thanks for sharing.

      I'm pretty sure there are some info in the videos that are not in the slides. Maybe you should try harder to get the videos.

      BTW, the link to the week 1 discussions is here:

      "Maybe you should try harder to get the videos."

      How about SAP buying more bandwidth?

      But no, there is not really much more information in the transcript PDF than in the videos.

      Thanks Tobias,

      I had problem in the request in Cordova, but including the user and password in the url, this was solved. Thanks!!!

      Good summary of the opening week experience (it was similar for me, right down to the video download speed issue), thanks for the post. Never mind more bandwidth from SAP for the video downloads; enough to keep the course website responsive during the last few hours of the due date of the weekly assignments would be a good start!

      To be fair though I want to give SAP credit where it's due here: this has improved dramatically since the last few weeks of the HANA course and I don't think SAP have run similar open online courses like these before now. I guess it'll take a while to get the infrastructure to an appropriate level, and at least they're trying -- it's great to see them get more open about education resources like this.

      Cool! I confess that I was curious about the training!

      Curious only? Are you also trying to attend the course? No pain no gain!

      Hi Tobias,

      Nice review.

      For someone who had never tried any mobility development like me either used Eclipse before, it was a very interesting week. I just think many people got lost because of some missing information such as the need to install Ant, how to create a virtual Android device (emulator) and the correct way to set up the environment variables etc.. specially who is not a developer and not used to install things themselves, but with the the help of the discussion forum they sorted it out. Being a newbie, I felt happy to help others in the forum and for being able to sort everything out by myself and see MyFirstApp working 🙂 .

      Hi Raquel,

        I'm going through the same experience. We are already in week 6 of this course and I'm learning lots about mobile. I'm looking forward to couple it with HANA and Cloud to do really new and cool stuff.

        Meanwhile, let me ask, are you from Brazil?


        Thank you for the very nice review! It´s an exciting time when all of us around the world can learn and work together.

      Best regards,

      Thanks for sharing this. Would you recommend cordova for cross-device development?

      Somehow the link above did not work for me, but I found this link for the mobile course: Course: Introduction to Mobile Solution Development for the Enterprise

      Hi Tobias,

      I have encountered the same problems, and I have try your methods. But it doesn't work! 😕 I don't know why? Could you give me some suggestions?

      And I can open the web page(W1U5_MyFirstIntegratedWebApp) through IE. But in chrome this will return 401(SAP NetWeaver Apllication [ES1/520]).

      And for W1U5_MyFirstIntegratedHWCApp, it also encountered the problem as yours. And I have try your method, but it doesn't work. 😕

      Could you give me some tips?

      Thanks for your help!
