Kivy is a open source Python library for rapid development, runs on Linux, Windows, OS X, Android, iOS, and Raspberry Pi. You can run the same code on all supported platforms.
You can run Kivy applications on Android, on (more or less) any device with OpenGL ES 2.0 (Android 2.2 minimum). This is standard on modern devices; Google reports the requirement is met by 99.9% of devices.
Kivy APKs are normal Android apps that you can distribute like any other, including on stores like the Play store. They behave properly when paused or restarted, may utilise Android services and have access to most of the normal java API.
