So let’s get started with building our project. Open up your terminal and type in the following command:

django-admin startproject myapp

This creates a Django application called myapp in your root folder.

Change directory to it by typing cd myapp and type in python runserver. Then you should get this:

Now the server has started. Next, to test it in the browser visit

And boom! You should see that Django has been setup successfully.

The next thing we need to do is create our Django app. In Django, the project folder serves as the root while the app serves as the application itself.

To create a Django app, make sure you are still in the directory, then type python startapp todo. This creates a To-do app in our myapp project like this:

Then inside the todo folder we should see something like this:

Issues In Creating Android App With Python

Though Android app development using Python is possible, it wont be as effective and reliable as Android app development using Java. As we all know that Java is the official language for Android, as Google declared it. Java for Android is like the Standard of Android, and other languages that we use might not be as up to the mark as Java. Let us see some of the issues that might occur:

  • Other frameworks might not support every feature of the Android operating system.
  • Own tools can not always be used.
  • These codes might not run very fast as they first generate the native code and then optimize using native compilers.
  • Sometimes the High-level graphics might not be supported.
  • The app you will develop will work perfectly fine on your local machine, but the animations are not smooth when running it on Android. Also, as it still runs as an instance of Python, it is slow.

Python has achieved greater heights and is overgrowing in recent years and thus can be used to develop applications in the coming years on both enterprise and product basis. Moreover, Python has proven itself as a competent language approachable for newcomers but powerful in the hands of experts.

    More Things We Can Do

    Android Chat App in Python

    That was a very simple introductory project to show you how Kivy works for the purpose of this Kivy Python tutorial.

    So, what else can this bad boy do?

    One smart thing we can do with Kivy, is to separate the UI layer from the code just as we do in Android Studio . We would do this by creating separate Kivy files that could then display buttons and the like.

    So, lets create a new Kivy file and name it HelloWorld. In here, add the following code:

    < label> :text: "Hello World"

    Make sure this file is saved in the same folder as your Python file using the extension .kv, and then edit the original code slightly:

    import kivykivy.requirefrom import Appfrom kivy.uix.button import Labelclass HelloWorld:    def build:        return LabelhelloWorld =

    Youll notice that all we did was to remove the contents of the brackets following Label. Its important that we give the class and the Kivy file the same name, as this is how Python knows to associate the two! Hit run, and you should find that everything looks just as it did before!

    Now you can do things like changing the color and size of the label:

    < label> :text: "Hello World"pos: 0, 100size: 100, 50color: .8,.9,0,1font_size: 32

    Note that for this to work, you also need to import color.

    from import Color

    This will simply stack your widgets top to bottom, or left to right, depending on whether you set it to verticle or horizontal.

    You can then display this using the following code:

    Some More Things To Consider

  • Performance Issues: The app you will develop will work perfectly fine on your local machine, but when you try to run it in android, the animations are not so smooth. Also, as it still runs as an instance of python, it is slow.
  • Convert to android: One of the major tasks is to convert the python Kivy application into an Android package and it can only be done on a Linux OS. The additional packages like python-to-android, Android SDK, bulldozer are heavy and require a lot of time to build and debug the app. All the Kivy and Kivymd libraries are converted into Cython, and these are used by the Android system. This process is usually done with high precision.
  • Still under development: This is an open-source project, and still a lot of work is going on under the hood. Always try to update the packages so you dont face any issues.
  • Using The Kv Language

    Kivy also provides a design language called KV that you can use with your Kivy applications. The KV language lets you separate your interface design from the applications logic. This follows the principle and is part of the Model-View-Controller architectural pattern. You can update the previous example to use the KV language:


    This code might look a bit odd at first glance, as it creates a Button without setting any of its attributes or binding it to any events. Whats happening here is that Kivy will automatically look for a file that has the same name as the class in lowercase, without the App part of the class name.

    In this case, the class name is ButtonApp, so Kivy will look for a file named button.kv. If that file exists and is properly formatted, then Kivy will use it to load up the UI. Go ahead and create this file and add the following code:

     1< Button> : 2    text: 'Press me' 3    size_hint:  4    pos_hint:  5    on_press: app.on_press_button

    Heres what each line does:

    You can set up all of your widgets and layouts inside one or more KV language files. The KV language also supports importing Python modules in KV, creating dynamic classes, and much more. For full details, check out Kivys guide to the KV Language.

    Now youre ready to create a real application!
