Python Download For Android
Rikke Reifel
Imagine building and running python applications, whether it's a command-line tool developed to fetch your favorite curated articles from the Internet, or starting a web server that runs right in the palm of your hand, all with just an Android mobile device and open source tools. This would change how you view your mobile device entirely, changing it from a device that merely lets you consume content to a device that helps you be creative.
python-for-android is an open source build tool to let you packagePython code into standalone android APKs. These can be passed around,installed, or uploaded to marketplaces such as the Play Store justlike any other Android app. This tool was originally developed for theKivy cross-platform graphical framework,but now supports multiple bootstraps and can be easily extended topackage other types of Python apps for Android.
python-for-android supports two major operations; first, it cancompile the Python interpreter, its dependencies, backend librariesand python code for Android devices. This stage is fully customisable:you can install as many or few components as you like. The result isa standalone Android project which can be used to generate any numberof different APKs, even with different names, icons, Python code etc.The second function of python-for-android is to provide a simpleinterface to these distributions, to generate from such a project aPython APK with build parameters and Python code to taste.
You can create a package for android using the python-for-android project. This page explains howto download and use it directly on your own machine (seePackaging your application into APK or AAB) oruse the Buildozer tool to automate the entire process. You can also seePackaging your application for the Kivy Launcher to run kivyprograms without compiling them.
Buildozer is a tool that automates the entire build process. Itdownloads and sets up all the prerequisites for python-for-android,including the android SDK and NDK, then builds an apk that can beautomatically pushed to the device.
This creates a buildozer.spec file controlling your buildconfiguration. You should edit it appropriately with your app nameetc. You can set variables to control most or all of the parameterspassed to python-for-android.
To do this, you must run Buildozer with the release parameter(e.g. buildozer android release), or if usingpython-for-android use the --release option to build.py. Thiscreates a release AAB in the bin directory, which you mustproperly sign and zipalign.The procedure for doing this is described in the Android documentationat -signing.html#signing-manually -all the necessary tools come with the Android SDK.
My project: Use MIT App Inventor on my Android phone (Currently Samsung Galaxy S9+ with Android version 10 but need it to run on any android); Send text to a Raspberry Pi (currently using a Pi4 but will be switching to Pi Zero W because I want to reduce the size); on top of the Pi 40 pin GPIO is a Waveshare servo driver hat (Which controls 16 servos, (I'm currently using the Waveshare sample Python code to get the 16 servos rotating, with minimal understanding of Python code.))
Want to build Android Apps in Python? More than 3 billion devices in this world run on android. That makes it one of the most or probably the most important smartphone OS in the world. Assuming the importance of android, there are a lot of android building tools such as Android Studio, Kotlin, etc.
As we have covered the basics of Kivy and discussed the widely used layouts and widgets present. Now we will be looking at how we can create a standalone app that can run on android phones. In the example below, we will be creating a search engine that takes user input and uses google API to output results.
