We should probably move the app in example down a layer since the text plugin includes things like text classification, language detector, and text embedding.

Do you think it's important to have separate samples for each work flow, or could they potentially be lumped into one demo with 3 different buttons to complete each task?

[PaulTR]

I'd keep them separated. We have one example per task in the other platforms, so keeping them separated helps us add examples for each over time

Also let's keep it simple and only have one sample to start per category. For Android we did text classification, audio classification, and object detection. We can flesh out the remainders via GSoC and my own development once we have a rough template so you're not spending all of your time on samples. Core functionality is definitely the priority, and I can focus on details/polish.

The latest commit should be working (or at least close to) from an implementation standpoint, but I'm getting segfault-like errors in my Android emulator.

So obsolete, you can't even imagine.
