user15492: To make clickable Bitcoin links, to let people easily pay from their wallet, I see two formats being used in various situations:
bitcoin:14bTZTm1uX2uVAqHr62oyGFEkwy2mNLbVb?amount=0.25
and
bitcoin://14bTZTm1uX2uVAqHr62oyGFEkwy2mNLbVb?amount=0.25
So that's with and without the two slashes. When testing on Android, they both seem to work. Which is correct?

user21052: The correct format is bitcoin:<address> as defined in BIP21 and extended in BIP72.
The format with the slashes is mimicry of the HTTP URL format.  Tim Berners-Lee has apologized for inflicting those extra slashes on the world. :-)
