What is Kivy?

Kivy is a library that allows you to use Python to create applications for mobile devices and desktops.

It takes your code and creates applications from your logic. Then, with each app and APK, it includes a nearly

complete installation of Python.

Write Once, Deploy to Many The biggest feature of Kivy is the ability to write code once and deploy that code to many platforms.

Master Data Science Career Skills

Everyone with a smartphone has felt the pain of seeing an awesome app come out for one line of phones, but never materialize for their particular phone.

Even more common is when a useful app comes out, but there’s no desktop equivalent.

Not everyone has access to a smartphone, or wants a certain app with them all the time.

There are quite a few games I wish existed on my computer, where I could have keyboard and mouse control, as well as some productivity apps, like task managers or certain alarm tools.

One developer can create for all of them, and then push a separately packaged application to each app store.

Though there are, in theory, some HTML5 inputs for

cameras, the coverage for this in browsers is spotty at best.

Video: Kivy includes modules for reading and playing videos. True, this can be done through a web app, but the experience can sometimes be shaky. Older phones might try

to play the video without taking up the whole screen, or the memory usage might be higher than it should be.

Multitouch and gestures: Kivy has a robust module for

input, allowing for multitouch and gestures.

Visual effects and OpenGL: Because Kivy has access to OpenGL, it can perform a large array of visual effects and do quite a bit of rendering.

Kivy also uses PyGame, so creating games becomes much easier (though you do have to rewrite existing PyGame code for Kivy).

PyGame comes with modules for drawing shapes, rendering, dealing with colors, and playing music (as well as blowing things up, naturally).

Asynchronous network requests: One important feature of any native app, at least for people like me who travel in and out of network areas, is the ability to finish requests when a network is available.

I like being able to work on my phone while in a tunnel, then have it sync my work to the cloud when I hit a station.

UI features: Kivy comes with a number of widgets and

controls that are beautifully designed.

This can be a real benefit to your project if you’re trying to prototype quickly, and don’t yet have access to a designer.

Example program

It doesn’t take very many lines of code to create a Kivy program. Here’s a sample ‘Hello, World’ application from the documentation: import kivy

kivy.require('1.0.6') # replace with your current kivy

from kivy.app import App

from kivy.uix.button import Button

class MyApp(App):

def build(self):

return Button(text='Hello World')

if __name__ == '__main__':

MyApp().run()

Layout in Kivy

CCNP and CCIE Enterpri se Core

CCNP and CCIE data center core

Kivy comes with a special language for defining layout.

This allows you to keep your logic and presentation separate. Kv (the layout language) isn’t complex, but you should review the documentation briefly before diving in.

A Kv file looks something like this: <ClassName>:

LayoutType:

WidgetType:

pos: self.center_x - 5, 0

size: 10, self.height

LayoutType2:

font_size: 70

center_x: root.width / 4

top: root.top - 50

text: "0"

So WidgetType is within LayoutType, and LayoutType2 is right after LayoutType. These are all stored in a view

called ViewName, which can be reused throughout the application by different views. As for the values to the left of the colon, those are Python statements. They might be as simple as a single value, or they might be a calculation of some kind.

There are a number of layouts and widgets available out of the box: Accordion: Expands or collapses items through touch or clicks ActionBar and ActionItems: Collects items you might want to give the user quick access to.

BoxLayout: Arranges children in a box, horizontally or vertically.

Bubble: Brings up a bubble with possible actions or information (like what is at a location, or giving the option to copy or paste the information) Button: Just what it sounds like! A button!

Carousel: Allows the user to swipe between slides And many more!
