Python android app tutorial

There are many reasons that you might want to start Android development. Building an app that will make you rich and change the world is only one motivation; others include learning to code, building tools that you can use yourself or even just having fun and impressing others.

Python is a particularly simple and elegant coding language that is designed with the beginner in mind. You need to set paths, figure out how to create APKs and add certain permissions on your phone. Even once all that is ready, you need to get to grips with things like views before you can actually show anything on the screen.

In short, this is one of the fastest ways to get up and running with some basic coding on Android. And yes, with a little playing around you can even build full APKs. Python is a relatively new programming language that was created by Guido van Rossum and released in Python is also the main programming language used with the Raspberry Pi, meaning that you can make a wide range of exciting gadgets with it.

This simplicity and elegance makes Python a great choice for new programmers but it also has a lot else going for it. For starters, there are interpreters available on multiple operating systems, meaning that you can run scripts on Windows, Mac, Linux and Android. Pinterest was written using Django! So, with that said, how do we go about getting started with Python? If you were learning Python for PC development, then you would begin by downloading the latest version of either Python 2 or Python 3 and then an IDE integrated development environment such as PyCharm.

Develop Your First Android Application in Python

You can get Python for Windows here. Python is an ongoing project that is constantly undergoing improvements. In order to ensure your code runs as smoothly as possible, you need to get the latest version of Python. At the time of writing, that is Python 3. The slight complication is that the jump from Python version 2 to Python version 3 was so significant, that it broke backwards compatibility.

That meant that code written in Python 2 would not work for Python 3 without some tweaks. A library as you may know is a collection of code that other developers can use in their own programs and that therefore shortens development time and enables additional functionality.

In future though, just know that you may need to revert to Python 2 so that you can support certain libraries. That is to say that if you want to create a basic tool to perform some maths, to test you on a subject, or to store and retrieve data… well then you can do! As you might guess, this is the editor where you can type out your code or edit other scripts.

Save by clicking the floppy disk icon at the bottom. That is to say that you can simply say that one word is equal to another word, or that it is equal to a letter. For example, if we use the following code:.

We could just have easily have said:. The real point of variables is that it allows us to dynamically change elements of our code. Likewise, we can create a little app that responds to the user like so:. Remember: variables are case sensitive! It makes sense to use capitals for variables in Python, seeing as the commands are always written in lower case.

It helps them to stand out! Using just these few bits of code, we can already do some fun things. A loop does exactly what it sounds like it should: it loops around and around until a certain set of conditions are satisfied. Add the following lines to the last script we wrote:.The demand for more applications is causing more and more developers to get into Android development, unfortunately until now the only way to develop for Android was to develop in Java.

But thanks to Google that one of their employee has come up with a solution that allows not only Python programmers but Perl, lua and bash programmers to develop on Android. If you like you can directly develop your Android application on your phone device. Download Android SDK. For Linux download the tar ball and for Windows download the executable recommended.

Install the SDK. When the new AVD is created, select it and click on Start. You will see a Android device emulator screen and an Android Logo, the Android OS is booting, you will have to wait for some time. After some time you will get a fully loaded Android OS on your Android emulator to develop and test your Android Application.

Scripting Layer For Android is the main Android Application you need to be able to run your Python applications on Android, so first you need to install SL4A on either your Android emulator or on the real Android device in case if you are going to do the development directly on your device.

Follow the steps below to install the SL4A on your Android. Once the Installation is complete go to SL4A application which is located under your applications menu. You will see some python scripts that got Installed along with Python for Android. Tap the second icon from left. The test. Note: The most left icon is to run the application in terminal, the second from left is to run the application normally, the third from left is to edit the script, the fourth from left to rename the script and the last one from left is to delete the script.

Now that our Android is ready and you have already tested that everything is working fine, its time to write your first Python application. You will write a very simplest version of hello world, this application will ask your name and then it will greet you. Thats it. Press the menu button on your Android device or Android emulator, and tap Refresh. You are done here.

Before starting installing Kivy and getting it up and running, it is required to install its dependencies. Most of the time is used for preparing the Kivy environment by installing libraries required for its operation. In this tutorial, Kivy itself is to be installed in a virtual environment. The platform used in this tutorial is Linux Ubuntu Some differences will exist when running Kivy on other platforms.

This tutorial has the following sections:. Kivy is used to create natural user interfaces with the advantages of abstraction and modularity. It decouples the developer from unnecessary and complex details and just gives simple APIs for doing complex tasks. As a result, you should determine what backend libraries that Kivy will use to do its tasks. Because such libraries are written in C, Cython is required.

Note that you could choose which Python version to use in Kivy by using python and python-dev for Python 2 or using python3 and python3-dev for Python 3.

Pip is installed below for later use in preparing the Kivy virtual environment. After preparing the Kivy dependencies, we can start installing Kivy by creating its virtual environment. It is not required to use a virtual environment to run Kivy but it is recommended to separate Kivy from other already existing projects.

Before starting creating the virtual environment, we should make sure that tools required for creating it are already installed and updated. The following command ensures that the virtualenv and setuptools tools are already existing and updated.

After that, we are ready to create the Kivy virtual environment. The following command creates an environment called mykivyinstall. The — no-site-packages argument is used to isolate the environment from the main Python installation.

This is to work freely on that project without affecting any other project. After issuing that command, it is expected to get a new folder in the current directory named according to the virtual environment name as in figure 1. The previous command will use the default Python interpreter within the environment. It may be Python 2 and we are looking to work with Python 3.

For such reason, we could explicitly specify which Python interpreter to use using the -p option as in the following command:. After creating the virtual environment, we can activate it to start installing Kivy. It can be activated based on the following command.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I would like to develop a rather simple android app to be distributed via Play Store. I would like to do so completely in python. I'm quite new to app development and would highly appreciate any leads of doing this in python rather than in Jave etc. To answer your first question: yes it is feasible to develop an android application in pure pythonin order to achieve this I suggest you use BeeWarewhich is just a suite of python toolsthat work together very well and they enable you to develop platform native applications in python.

Android's preferred language of implementation is Java - so if you want to write an Android application in Python, you need to have a way to run your Python code on a Java Virtual Machine.

This is what VOC does. VOC is a transpiler - it takes Python source code, compiles it to CPython Bytecode, and then transpiles that bytecode into Java-compatible bytecode. The end result is that your Python source code files are compiled directly to a Java. VOC also allows you to access native Java objects as if they were Python objects, implement Java interfaces with Python classes, and subclass Java classes with Python classes.

Once you've written your native Android application, you can use Briefcase to package your Python code as an Android application. Briefcase is a tool for converting a Python project into a standalone native application. You can package projects for:.

Python for Android: Start Building Kivy Cross-Platform Applications

You could try BeeWare - as described on their website:. One codebase. Multiple apps. Gives you want you want now to write Android Apps in Python, plus has the advantage that you won't need to learn yet another framework in future if you end up also wanting to do something on one of the other listed platforms.

Here's the Tutorial for Android Apps. To quote the site "The complete Android API and user interface toolkit are directly at your disposal. This provides a multi target transpiler, supports many targets such as Android and iOS. It uses a generic widget toolkit toga that maps to the host interface calls. Beeware Toga like all widget libraries is good for getting the basics out to multiple platforms.

If you have basic designs, and a desire to expand to other platforms this should work out well for you. It also allows you to mix in Java, useful if you want to use existing code from other resources.

If you have strict design targets, and predominantly want to target Android this is a much better resource. When I saw these two keywords together in your question, Kivy is the one which came to my mind first. It just awesome.

Here are a few advantage I could find out.

Open source. At least few of it's Cross platform competitors want you to pay a fee if you want a commercial license. Kivy 's graphics engine build over OpenGL ES 2 makes it suitable for softwares which require fast graphics rendering such as games. Here is a detailed guide for setting up the development environment. Learn more.As we know python is growing very fastly and many applications are creating with python. Many android applications are available to run the python scripts on android devices.

You can implement all your programming logics on these devices as you do them on PCs. And in this tutorial i will explain QPython3 rather than others.

More than 2 for this - nice bonus. The event moves away from its established venue at Royal Johannesburg to Randpark this year. This will be the first time this course has staged a European tour event since the South African Open in 2000 won by Matthias Gronberg.

With a large field competing two courses, The Firethorn and The Bushwillow, will be used over the first two days before reverting to the Firethorn course over the weekend. The Firethorn course at 7,600 yards is almost 500 yards longer than Bushwillow so is likely to play a bit tougher.

Local boy Porteous has good memories here having won an amateur event here by 14 strokes only a few years ago.

Since then he has gone on to establish himself as a very promising tour player having won the 2016 staging of this event at Royal Johannesburg. His recent form has been dogged by inconsistency with too many rounds spoiled by the odd big number at one or two holes but he did show up well in the Nedbank and DP World event recently so we have some grounds for optimism this week back in familiar surroundings. Another local boy Walters represents Johannesburg CC just down the road from Randpark so he knows these courses well.

Recent form was poor until it picked up last week in Mauritius where he finished tied fourteenth despite a poor closing round. He is yet to record a win on tour but in such a weak field and in his own backyard if he is ever going to break through it might well be here.
