I keep running into discussions about multi-touch on the Droid (or lack there of), and about multi-touch in Android in general.
Being a developer who has, among other things, (1) developed a Multi-touch API for Android, and (2) developed Multi-touch applications for all versions of Android, I have the inside scoop on this issue and thought I'd share it.
Fact 1: Android was released without Multi-touch support (1.0, 1.1, 1.5, 1.6)
Opinions vary about why this is so; some say legal issues, some say secret agreements. I don't know why, but I know what. Android was unable to report the location of more than one finger at a time. It has always been possible to simulate pinch/stretch zooming, although we're not aware of any applications that do it but ours (PhoneMyPC, and the recently released Beta of 'Imagine Multi-Touch').
Fact 2: Android 2.0 has 'true' Multi-touch
This includes the Droid. The Android 2.0 software is capable of handling up to three fingers simultaneously; the Droid only supports 2 (whether it's a hardware or software limit, I'm not sure).
Fact 3: The Droid apps are not Multi-touch
This isn't for any technical reason; the device, and the OS can do it. Google chose not to use this feature in the Gallery, Browser, etc., but they have chosen to do so for the European version (Milestone).
Fact 4: 3rd party apps can use Multi-touch on the Droid.
PicSay, PhoneMyPC, Imagine Multi-Touch all use multi-touch on the Droid, and the latter two do so on all versions of Android. I have a friend who's developing a multi-touch browser using the same technology we use in our products, so one will be available soon for we USA Droid'ians.
So, Droid owners, rest easy that your device has got the latest capabilities. Blame Google for not giving you multi-everyting out-of-the-box, but rest easy: developers will fill the gaps, and we'll be swimming in a sea of multi-finger fun in no time.
