I've been working on an easier way to sideload apps onto the Supernote. I see posts on here about how difficult, cumbersome, and technical it is, and there's a lot of confusion about what all is required. So I made an app for Windows, Mac, and Linux to make sideloading as easy as possible. No need to download any SDKs or drivers, and no need to use the command line or mess with environment variables.

The app is free and open source: https://github.com/ryan-andrew/android_sideloader

There are detailed instructions for downloading and running the app on the GitHub page. I made this specifically for my Supernote, since I have no other devices that need sideloading. It works for all Android devices though, so the steps on there aren't tailored to Supernote.

Enabling Sideloading

1. On your Supernote, open Settings
2. Go to the Security & Privacy tab
3. Turn on the Sideloading option
4. Tap Accept and Enable on the next screen

After sideloading is enabled, download the app from GitHub, and follow the instructions if you need help.

Sideloading an app only takes seconds

I've tested it on a few Windows PCs, but Mac testing has been limited. Please let me know if there are any issues and I'll fix them as soon as I can!

I know installing is still a bit of a chore. I'll work on getting this into the Windows and Mac app stores as well to ease that friction. I want sideloading to be as easy and approachable as possible! Ratta has announced their plans to open up to third party developers, and I'm excited about developing for it!

Edit: I've added support for Linux in the new 1.2.0 release. This was tested in an Ubuntu virtual machine with virtualized USB devices, so there may be issues I couldn't see, but it works well for me.
