Utilize some KTX and fix a deprecation

[TacoTheDank]

What does this implement/fix? Please describe.

• The first two commits replace some things. These do the jobs of the removed functions internally.
• The third commit fixes a deprecation
• The fourth commit utilizes a Fragment KTX extension

Does this close any currently open issues? No.

Additional context

• parseAsHtml calls HtmlCompat.fromHtml internally
• PackageInfoCompat.getLongVersionCode does the API check internally

Where has this been tested? No testing required... but I tested on my phone anyway. Everything works fine.
