How to write Android programs in python

We use kivy to develop Android APP. Kivy is a set of open source frameworks specially used for cross-platform rapid application development. It is written in Python and Cython. It has very good support for multi-touch, which not only allows developers to complete the application quickly With simple interactive prototyping and support for code reuse and deployment, it is definitely an amazing NUI framework.

Because it is cross-platform, you only need to write the code once to generate Android and iOS APPs at the same time, which is cool.

Take everyone to write a Hello world

kivy installation
Environment description: The author is using Python2.7.10
Here we only introduce the windows platform installation
Reference for all platforms: https://kivy.org/#download

Update pip, setuptools

python -m pip install –upgrade pip wheel setuptools

Then install the required dependencies

python -m pip install docutils pygmentspypiwin32 kivy.deps.sdl2 kivy.deps.glew \ 
kivy.deps.gstreamer –extra-index-url https://kivy.org/downloads/packages/simple/

It is worth noting that the above Android needs to access Google, so please bring your own ladder, and the kivy.deps.gstreamer package is relatively large (95MB) and can be installed locally alone,
Then install kivy

python -m pip install kivy

At this point, the installation is complete. It is worth noting that the 64-bit system does not have virtualization support enabled. An error will be reported when importing kivy. If it is 64-bit Just set the machine's BIOS and enable virtualization support.
Note: This is just the running environment of kivy, so that I can debug it directly on the windows machine. We will talk about how to compile the code into an APK file later.

If kivy is in python, it should be able to be imported.

According to world practice, let’s say “hello”.
Create a new .py filehelloworld

from kivy.app import App from kivy.uix.button importButton
class TestApp(App): def build(self): return Button(text=’Hello,kivy’)
TestApp().run()
