convert (update) a program written in Windows into one written for Android. It is a graphing program. It was done once, but Android Studio no longer compiles it for some reason, so I can't update it.

I am looking for someone to help me with a project. I need to convert (update) a program I had written for Windows into one written for Android. It's a graphing program, and the initial program was written in C#. Fortunately, I still have the source code from the Windows version, so it will be easier for you to replicate the same program in the Android version. There are no specific features or updates in mind for the Android version. The goal is to replicate the existing program I have in Windows. If you have experience with developing graphing programs for Android and believe you have the skill set necessary to complete this project, I would welcome the help. I have an older version of the Android program, but can't get it to compile on my new computer. I will own the code developed.
