Ubuntu Touch Programming Course



  • Good afternoon.

    In August of last year I started writing an Ubuntu Touch programming course. Now I am translating it into English. You can see the content of the course (until now) in the next panel of Trello.

    I have written about generic topics with QML and JavaScript at the moment. The same code can work on the desktop, both in GNU / Linux and WIndows.

    Do you have any suggestions? I hope to translate one delivery per month although it depends on the free time you have.


  • Community

    This is looking more fab each time I look at it

    I looked at this as an app and found it really interesting. Thanks for sharing and also thanks for all the hard work that has gone into this



  • This really is a great work you are doing! Just want to say 'Thank you!' and ask to finish the whole thing, it will be a great place for any beginner to really get 'hands dirty' with the code!



  • To make it easier to follow the course I will define a fixed date in which I will publish the translation of a chapter. If no unforeseen arise, I will publish a new chapter in the last weekend of each month.

    The next delivery will be on Saturday April 29 and will include:

    • CH3 - Creating a Web App
    • CH4 - Creating an Application with QML (1)

    The course can be downloaded in ePub, PDF and Mobi formats. If you have any problems with the downloads do not hesitate to comment.



  • Goodnight.

    I just published the translation of two new chapters of the course:

    • Chapter 03: Web Apps.
    • Chapter 04 - S01: Introduction to QML language.

    You can read them in the course book



  • I would try to translate your English translations into German, if that is possible. I have never worked with GitBook, is there any functionality letting me translate it?



  • Hello flyingP0tat0

    GitBook has no tools to do the translation. The workflow could be:

    • I share the document in English in Google Docs.
    • On that document you do the translation.
    • After reviewing the translation, I incorporate it into the course as one more language.

    This way you work on a text editor and you do not have to know how GitBook works.



  • Yep, sounds great. I can also just translate from the PDF GitBook provides and send you the Google Doc afterwards.



  • It is easier to work on the document because it can be edited. I give you the access details by private.



  • Good afternoon.

    These last two months have been a little chaotic and I have not been able to devote time to the course. If I have no problems, I will publish two chapters at the end of the week.



  • I comment you the state of the chapter:

    • The source code is now complete. You can check it at GitHub
    • The calculator after the end of the chapter has the following appearance

    I have to review the text and edit the chapter. I'll let you know when I have it published. I do not know if it will give me time to finish it this weekend.

    PD: I have published the source code that generates the book. It is also in GitHub (Book)



  • Good evening.

    I have already published the next course chapter:

    • Organizing components
    • The Row Layout
    • Grid Layout
    • The Button
    • Color Settings
    • Changing the Button Size

    You can read it on the course website



  • Very nice, thank you!

    While scanning through it, I see lot's of replicated code in the last example with the Buttons. Isn't there a way to make something like a CalcButton, which has all the common properties (sizes, color) and can be reused. I don't actually know what the syntax for this is (guess why I'm interested in a UT programming course :-P ), but I expect that this is possible and would be a nice rounding up of the chapter.



  • Hi @doniks,

    You're right, but the code may still get worse. In a calculator there are buttons that have two or three functions. So far you have seen the buttons of the basic calculator but there is also a scientific calculator.

    In one of the future chapters (it is written in Spanish and I have not yet translated it), a custom component is created that contains the button and the extra functions. You can see an example between the current design and the future.

    Design comparative

    Both versions use QML. Just change the design. If you have any questions related to the chapters that are published do not hesitate to ask.



  • Great that you write this tutorial for us :-)

    I have follow the instructions to install the SDK.
    So far so good.
    but i can not install the developer kitś.
    I get every time the following error message:

    Creating image with: framework: ubuntu-sdk-15.04 arch: amd64
    error: No storage pool found. Please create a new storage pool.
    ---Task exited with errors, please check the output---

    Why it can not find the pool? Have I forgot something?
    System is up to date.
    Ubuntu SDK IDE is installed.
    PPA is added.
    Iḿ in the usergroup lxd.
    PC is restarted

    What version of Ubuntu are you using?



  • Linux Mint 18 Cinnamon 64-bit

    Have I to use the Ubuntu Gnome Desktop?



  • @TischlerWilly,

    It may be a particular Linux Mint bug. This weekend I can create a virtual machine and check if I can replicate the bug. The course I'm programming in Ubuntu 16.04 with the Mate desktop (although it should work with any desktop).



  • Hi guys.

    At the end of the week I'll be uploading the resources I used at Ubucon Paris 2017. The virtual machine uses Ubuntu Mate 16.04 and has the SDK ready to work. Just download the file, configure VirtualBox and start programming applications.

    The link to the presentation is temporary, when I publish it I will update the link.

    I hope at the end of the month to upload the translations of several course sessions. My intention is to match the Spanish and English versions before continuing with the new content.



  • Good afternoon.

    You can now download the resources I used in the UbuconParis 2017 workshop. The virtual machine has the following features:

    • Ubuntu 16.04 with the Mate desktop.
    • SDK already configured with IDE icon on the desktop.
    • The workshop exercises are saved in the User Folder.

    The credentials are:

    • User: ubucon
    • Password: ubucon

    Links are public. I would ask you to download the resources using the short link because that way I can have some statistics.

    It is possible, in the future, to add new elements to the virtual machine. It all depends on the suggestions you make. If you have any problems with the file you can indicate it in this thread.

    I hope to publish new translations of the course next week. When the English and Spanish versions are ready, I will create new content.for both.
