So, let's get ready to unlock the power of Python for mobile app development.

Why should we use Python for mobile app development?

Python is increasingly becoming a go-to choice for mobile app development, thanks to its integration with powerful GUI frameworks like Kivy and BeeWare.

While Python alone may not be optimized for mobile device app development, these frameworks step in to seamlessly translate interpreter-based code into native code suitable for mobile platforms.

This combination offers developers a significant technical advantage, particularly in cross-platform development.

Traditionally, developing mobile apps for both iOS and Android meant navigating the complexities of using different programming languages and tools for each platform.

This approach required building separate codebases from scratch, essentially doubling the workload and introducing the challenge of ensuring consistency across versions.

However, modern Python frameworks like Kivy and BeeWare revolutionize this process by serving as a bridge, enabling developers to write their app once in Python and effortlessly adapt it for various platforms.

This not only streamlines the development process but also centralizes the codebase, simplifying maintenance and ensuring consistent functionality across different devices and operating systems.

Ultimately, Python's compatibility with these frameworks offers a practical solution for efficient and effective mobile app development.

Let's develop and package small mobile application (Background color changer) with python kivy

1. Installing Kivy

To install Kivy, you can use pip, Python's package manager. Open your command line interface (CLI) and run the following command

1pip install kivy

This command will download and install the latest version of Kivy and its dependencies. Once the installation is complete, you'll be ready to start using Kivy for mobile app development with Python.

2. Development of app

Importing necessary modules from Kivy framework for building the GUI application.

1import kivy
2from import App
3from kivy.uix.floatlayout import FloatLayout
4from kivy.uix.gridlayout import GridLayout
5from kivy.uix.button import Button
6from import Color, Rectangle
7from kivy.uix.boxlayout import BoxLayout
8from kivy.uix.widget import Widget

Defining a class named MainScreen that inherits from FloatLayout. This class represents the main screen of the application.

1class MainScreen(FloatLayout):
2 def __init__(self, **kwargs):
3 super(MainScreen, self).__init__(**kwargs)

Creating BoxLayout and GridLayout instances. BoxLayout is set to stack widgets vertically, while GridLayout is set with 3 columns, spacing of 5 pixels between widgets, and a fixed size of 300x300 pixels.

1				box_layout = BoxLayout(orientation='vertical')
2 grid_layout = GridLayout(cols=3, spacing=5, size_hint=(None, None), size=(300, 300))
3 grid_layout.bind(minimum_size=grid_layout.setter('size'))

Iterating through a list of color hex codes and creating buttons with those colors as background colors. Each button is given a fixed size of 100x100 pixels and bound to the change_background method when pressed. These buttons are added to the grid layout.

1        colors = ['#FF0000', '#00FF00', '#0000FF',
2 '#FFFF00', '#FF00FF', '#00FFFF',
3 '#FFA500', '#800080', '#008080']
5 for color in colors:
6 button = Button(background_color=color, size_hint=(None, None), size=(100, 100))
7 button.bind(on_press=self.change_background)
8 grid_layout.add_widget(button)

Adding spacer widgets (empty Widget instances) above and below the grid layout to center it vertically within the main screen. Then, adding the box layout containing the grid layout to the main screen.

1        box_layout.add_widget(Widget())  # Spacer
2 box_layout.add_widget(grid_layout)
3 box_layout.add_widget(Widget()) # Spacer
5 self.add_widget(box_layout)

This method is called when any button is pressed. It clears the canvas before drawing and draws a rectangle with the color of the pressed button as its background color, effectively changing the background color of the main screen.

1    def change_background(self, instance):
2 self.canvas.before.clear()
3 with self.canvas.before:
4 Color(*instance.background_color)
5 Rectangle(pos=self.pos, size=self.size)

Defining the MyApp class that inherits from App, and the build method that returns an instance of the MainScreen class. Finally, running the application by creating an instance of the MyApp class and calling its run() method.

1class MyApp(App):
2 def build(self):
3 return MainScreen()
5if __name__ == '__main__':
6 MyApp().run()

Now let's run this file. I have save the file name as "". Run the following command in the terminal at the same path where file is saved.
