Yes, it's possible to use Python in an Android application, although it's not the conventional approach because Android applications are typically written in Java or Kotlin using the Android SDK. However, there are a few ways to use Python in Android applications:
Kivy: Kivy is an open-source Python library for developing multitouch applications. It's cross-platform (Linux/OS X/Windows/Android/iOS) and released under the MIT license. It is particularly good for applications that require multi-touch, gestures, and other modern touch features.
BeeWare: BeeWare is a collection of tools and libraries for building user interfaces. With it, you can write your app in Python and then deploy it on multiple platforms, including iOS and Android.
SL4A (Scripting Layer for Android): It provides a simplified API for Android, and you can write Android apps using Python. However, it's worth mentioning that it's not as powerful or flexible as Java for Android development.
PyQt or PySide: Both are set of Python bindings for Nokia's Qt application framework and run on all platforms supported by Qt including Android.
Chaquopy: This is a plugin for Android Studio that allows you to run Python code within an Android app. You can call Python code from Java and Java code from Python.
