Android 2.2 and Its Previous Versions: A Sweet Developer Review

“The Android platform has really matured in the past year or so.
With the latest Android 2.2 SDK just released at Google I/O 2010,
we thought it would be fitting to do a little review of how far the
platform has come.

“In typical tech-sector lingo, the Android development team has
used a naming theme for all the Android SDK versions, naming each
(alphabetically) after sweets: Cupcake (Android 1.5), Donut (1.6),
Éclair (2.0), Flan (2.1), FroYo (2.2), and the upcoming
Gingerbread (3.0). Despite being referred to as “minor,” many of
these releases have had major implications for developers and
carrier/operators — not to mention users.

“The Android development team has been adding features to the
platform at a fast and furious pace — maybe too fast for some. In
the past 18 months, they have produced eight separate Android
releases, each of which was deemed important enough to have its own
API Level number. Statistically, since Android 1.5, 19 new packages
and 172 new classes have been added to the Android SDK. Along the
way, even more changes (additions, removals, improvements, bug
fixes, etc.) have been made to existing classes.”
