How to build an Android app
One of the strengths of the Android platform compared to iOS, for example, is that it has an open source basis, which makes it easier to produce your own applications and distribute them without waiting for a lengthy approval process. You can set up your own Android app on your PC as long as you have the right software installed, and you can even take it for a test drive using an Android emulator so you can see what it will look like when it's run on a smartphone. There are two techniques that you can use to produce Android applications with a PC. The first uses the Android Software Development Kit (SDK).
Developing Android Apps completely in Python
The goal of this training is to show you how to start developing full Android applications using only Python. Different technologies will be demonstrated, including PySide-based QML GUIs using the Necessitas Qt port and the Py4A/SL4A-based approach, which can be combined with Android’s WebKit and re-use Python web frameworks. While Android already has a good SDK out of the box, being able to use Python instead of Java is a big advantage for some developers - it allows for quicker turnaround times, and reuse of Python libraries. Python on Android uses a native CPython build, so its performance and compatibility is very good. Combined with PySide (which uses a native Qt build) and Qt’s support for OpenGL ES acceleration, you can create fluent UIs even with Python.
