One indication, he said, is that the 71% of developers who said they were "very interested" in Android on tablets wasn't matched with similar numbers when they were asked about interest in specific hardware. Only 51% said they were very interested in developing for the Galaxy Tab, and just 44% said the same of the Xoom.
"There's a value disparity between Android tablets in theory and Android tablets in reality," said Schwartzhoff, referring to the 20-points-and-more split. "That difference in trajectory is the most interesting thing to watch in the next months."
Schwartzhoff also attributed some of the fall-off in Android interest to continued concern by developers of fragmentation, a term typically used to describe the multiple versions of the operating system out and about on both old and new smartphones.
But Appcelerator sees fragmentation as a bigger issue.
While nearly two-thirds of developers said that fragmentation was their top concern, when Appcelerator and IDC dug deeper, the Android OS fragmentation issue came in third, with 21%, behind other answers, including skills fragmentation (33%) and OS fragmentation (22%).
"Fragmentation on Android is six layers deep," said Schwartzhoff, explaining that all mobile application developers face problems finding skilled programmers, keeping up with the rapid changes in operating system differences, and managing a suite of apps that must be maintained or ported to another platform.
"Set against this, Android fragmentation piles on top of an already sore spot," said Schwartzhoff, noting that iOS-only developers don't face the problems of multiple handsets, multiple OS editions, multiple app stores.
"Fragmentation is hugely important, and also cumulative," said Schwartzhoff. "And now Android developers are being asked to add in tablets?"
Something has to give, and apparently, it's Android tablets that some are willing to abandon, at least for now.
"These are big concerns," said Schwartzhoff, "because Android developers know they have couple of major issues right out of the gate."
