Dev Sprint Summaries/Blog Posts

  1. Our First Dev Sprint meant to get people familiarized with kivy.

After this first Devspring it was decided that we would start working on the app from scratch. For this purpose the master branch was emptied and we have started with blank dir.

Step 1: We setup a basic structure for the app

PyCon-Mobile-App
|
|___ LICENSE
|___ Makefile
|___ README.md
|___ eventsapp
       |___ main.py: "This is the main entry point of our application"
       |___ uix: "This is where our user interface elements go."
             |___ screens: "This is where all our UI screens of the app go."
|
|___ tools: "This is where all our tools including assets etc go."
       |___ images: "This is where all our image assets go."
       |___ raw_assets: "This is where our raw assets from the design team exist."
|___ tests: "All our tests go here"

This is the current app structure, Currently the main.py just has the following data.

from kivy.app import App


class EventsApp(App):
    '''This is our entry point for the application
    '''

    def on_pause(self):
        # allow the app to pause on android and ios
        # set this to False if you do not want that.
        return True

    def on_resume(self):
        pass

# is our app running as main or is it being imported as a module?
if __name__ == '__main__':
    # our app is running as main
    # let us instantiate the app and run it.
    EventsApp().run()

So this gives you just one simple blank window with nothing in there.

Step 2: Design And Architecture of the project

Keeping in mind the following items::

  • UI Design of the app ref
  • Features ref
  • Usage pattern of the app

Saturday August 19: We will be sending out a mail to each volunteer group asking for their input on how they want to use the app. This should help us get a better idea of how to have the app designed.

Till that we will be starting with a basic app loads basic screens

The SplashScreen

Starting from the blank screen in step one, The first thing that happens in our app should be the display of logo on splash screen.

Let's first add a load_screen method in our main.py. This method would be used/called by anyplace in our app to load a screen in any given ScreenManager.

Now what is a ScreenManager?

A ScreenManager is a Widget that houses multiple screens that can be loaded in it. using different types of transitions, for more info in the subjects please look at https://kivy.org/docs/api-kivy.uix.screenmanager.html
