[Android] Rewrite Entire Application

[zakuArbor]

I cannot install the app onto my phone and setup android studio. A lot of things are deprecated. It's probably more productive to rewrite the code and also review how Kotlin works

Unfortunately, the new app will target Android 9 which will target 39.5% of Android devices. There needs to be a balance between acessibility and security. I could have chosen Android 8.1 but I wanted to choose a version of Android that will be supported by the time I make sufficient progress (which I estimate to be December 2021 because I'll be busy with school).

App Flow

• when the user opens the app, they'll be shown a list of previously connected devices
• when a user selects a device, they will automatically try to connect and authenticate
• each item in the list will have a gearbox where they can edit and see device information

Closing this one as it'll be a duplicate of #61
