This repository contains the source code of the Pendulum Studio app, badly updated for modern versions of Android up to API 35 (Android 15) and down to API 15 (Android 4.0.3).
It is designed to be used in Android Studio with Gradle.
- Changed compileSdkVersion from 25 (Android 7.1) to 34 (Android 14)
- Changed minSdkVersion from 9 (Android 2.3) to 15 (Android 4.0.3)
- Changed targetSdkVersion from 28 (Android 9) to 34 (Android 14)
- Updated some dependencies
- Using Theme.AppCompat instead of Theme.Holo.Light
The app simulates the motion of various pendulum systems in real-time and renders it on the screen of an Android device. The Euler-Lagrange equations of motion for a chosen system are solved numerically by applying the Runge-Kutta-Fehlberg method at each time step. The visualization is performed using OpenGL.
