Why convert PY to APK?
Android apps run on the Dalvik/ART virtual machine, which executes DEX bytecode; Python does not compile to DEX. An APK must contain an AndroidManifest.xml, compiled classes, and resources - none of which exist in a plain .py file. Any approach that puts Python code on Android must bundle a full CPython interpreter inside the APK.
How to convert PY to APK
Kivy + Buildozer OPEN-SOURCE
Write your app using the Kivy GUI framework, then run Buildozer on Linux to cross-compile and package it as an APK that includes the Python runtime.
BeeWare / Briefcase OPEN-SOURCE
Build your app against the BeeWare Toga UI toolkit, then run briefcase build android to produce an APK with a bundled Python interpreter.
About these formats
A .py file is a Python source code file - plain text containing a program or script written in the Python language. To read the code, open it in any text editor. To run it, install Python…

Open .APK details →Quality & what to watch
- Neither Kivy/Buildozer nor BeeWare is a file converter - both require restructuring your script as a proper app with a UI framework and an Android SDK toolchain.
- The resulting APK is large (typically 20-40 MB or more) because it contains a full CPython interpreter; this is unavoidable for Python apps on Android.
- If you only want to run a
.pyscript on an Android device without building an APK, apps like Pydroid 3 or Termux let you run.pyfiles directly on the device.
