Android: Update docs to be more explicit

Explicitly call out what flag needs to be changed if a new SDK location
is desired for Android Studio. This way the change is explicit and we do
not fall into the trap of recommending the default location Android
Studio suggests, which unfortunately happens to just be the last-used
sdk location.

We now recommend emulators so no need for the emulator warning section.

~/Android/Sdk is now the default, so removing blurb.
