This is a mobile application developed in Kotlin using Android Studio. It simulates the mechanical movement of a spring attached to a mass.
Here are some important files that you need to check out :
-
MainActivity.kt : This file contains the program that makes the application work. The file is located at : Spring_Mass_Simulation\Spring_Mass_Simulation_Kotlin\app\src\main\java\com\example\spring_mass_simulation_kotlin\MainActivity.kt
-
activity_main.xml : This file contains the interface that makes the application work. The file is located at : Spring_Mass_Simulation\Spring_Mass_Simulation_Kotlin\app\src\main\res\layout\activity_main.xml
-
drawable : This folder contains pictures and XML files used for activity_main.xml. The folder is located at : Spring_Mass_Simulation\Spring_Mass_Simulation_Kotlin\app\src\main\res\drawable
-
raw : This folder contains the MP3 file for the button click sound. The folder is located at : Spring_Mass_Simulation\Spring_Mass_Simulation_Kotlin\app\src\main\res\raw
I use the Pixel 2 API 30, with a size of 5.0", and a resolution of 1080x1920.
