To start Android app development with Python, there are various platforms that enable us to write the codes purely in Python. We can use python for web development, app development, analysis and computation of scientific and numeric data and software development.
The Kivy Launcher is an Android application that can run any Kivy appstored in the kivy folder on the SD Card. You can download the latest stableversion for your android device from thePlay Store.
The stable launcher comes with various Python packages andpermissions, usually listed in the description in the store. Thosearen’t always enough for an application to run or even launch if youwork with other dependencies that are not packaged.
Those aren’t always enough for an application to run or even launch if you work with other dependencies that are not packaged. The Kivy Launcher is intended for quick and simple testing. For anything more advanced we recommend building your own APK with python-for-android. QPython is the Python engine for android.it already has millions of users worldwide and it is also an open source project. It contains some amazing features such as. Android Python interpreter; Python android runtime environment. Python editor; QPYI and SL4A library; It supports running multiple types of projects, including: console program. To view the Android logs without the background noise from the rest of the system, you can run adb logcat-s MainActivity:. stdio:. Python:. Anything your app writes to stdout (e.g., the output of print statements) will be visible in the logs. While Android and iOS will not run interpreted code, you can use a Python mobile app framework like Kivy or BeeWare to write your mobile application in Python and then cross-compile it for Android or iOS.

Building¶
The Kivy Launcher is built using python-for-android. To get the most recentversions of packages you need to clean them first, so that the packager won’tgrab an old (cached) package instead of a fresh one.
Note
–minsdk 13 is necessary for the new toolchain, otherwise you’ll be ableto run apps only in landscape orientation.
Warning
Do not use any of –private, –public, –dir or other arguments foradding main.py or main.pyo to the app. The argument –launcher isabove them and tells the p4a to build the launcher version of the APK.
Usage¶
Once the launcher is installed, you need to create a folder in yourexternal storage directory (e.g. /storage/emulated/0 or/sdcard) - this is normally your ‘home’ directory in a filebrowser. Business in a box training. Each new folder inside kivy represents aseparate application:
Each application folder must contain anandroid.txt file. The file has to contain three basiclines:
The file is editable so you can change for example orientation orname. These are the only options dynamically configurable here,although when the app runs you can call the Android API with PyJNIusto change other settings.
After you set your android.txt file, you can now run the launcherand start any available app from the list.
To differentiate between apps in /sdcard/kivy, you can include an iconnamed icon.png in the folder. The icon should be a square.
Release on the market¶
Launcher is released on Google Play with each new Kivy stablebranch. The master branch is not suitable for a regular user becauseit changes quickly and needs testing.
Source code¶
If you feel confident, feel free to improve the launcher. You can find thesource code at |renpy|_ or at |kivy|_.
Python has been ported to a number of specialized and/or older platforms,listed below in alphabetical order. Note that these ports often lagwell behind the latest Python release.
AIX binary packages for Python3 and Python2 are provided by AIXTOOLS for no-charge. The packages are supplied in installp format (not RPM format). Fallout 4 save cleaning. There are no pre-requisites other than a recent version of openssl.base.
See the AIXTOOLS wiki for additional details. The download page for Python 3 is at http://www.aixtools.net/index.php/python3 and the download page for Python 2 is at http://www.aixtools.net/index.php/python2.
For issues concerning the installation of AIXTOOLS packaging of Python please post your issue at http://forums.rootvg.net/aixtools.
Python Interpreter
Both Python 2 and Python 3 are available from IBM in RPM form. They can be installed with the yum package manager or with the IBM i Access Client Solutions product. To get started with RPM-based open source packages for IBM i, visit http://ibm.biz/ibmi-rpms.
These RPM packages require a version of IBM i in active (not extended) support. Alternatively, http://www.iseriespython.com hosts an IBM i port of Python 2.7, ported by Per Gummedal, which can also be run on older versions of the operating system.
Pythonista is a complete development environment for writing Python scripts including third-party libraries and system integration on your iPad or iPhone.
Pyto also provides a complete development environment for running Python 3 including many third-party libraries and system integration on an iPad or iPhone.
Rocket Software provides a port of Python for z/OS. They support both Python 2 and Python 3.
Python is available for RISC OS, and can be obtained using the PackMan package manager.
