TODO: Known Issues: If the mention or hashtag contains a piece of puntuation, the .word granularity for the tokenizer does not properly work. While I have come up with a pretty terrible solution using a for loop, it is definitely not the way to go. This issue is pretty low priority for my purpose but if anyone knows how to build a custom tokenizer, I would appreciate the help!
Currently using a constant value to perform granularity. This means that while the TextView works great for most common font sizes ie. 6-16 or so, it will not be perfectly accurate for others. I might create a custom algorithm to get the pixel width of specific font sizes.
