Cheers. It's no great shakes. Just another generic "here's how you do things in Android" with a list of hardware and a (very small) caveat that you need to be on <this> version rather that <that>. Even if <this> version is 5 years old.
The older I get, the more irritated I get by the floppy-fringed gee-whizz of the young hipster brigade trying to convince me that some ill-thought out, badly designed, appallingly executed POS feature/gadget/app is proof that we're somehow living the Star Trek dream.
One thing these whippersnappers don't know (and that's the closest you'll get to a tacit admission that at one time *I* may have been a young hipster) is that 80% of "new" is actually "old". Indeed (in computing terms) "very old". AI ? read "2001". VR ? "Tron". And so on. iPhone ? Psion.
