Google has updated its Android roadmap with more information for developers, including details on the upcoming second round of the Developer Challenge.  Following this week’s release of v0.9 of the Android SDK, the next significant roll-outs will take place during September as the company tweaks the open-source platform, in response to bug sightings and developer requests.

The full Android v.1 SDK is scheduled for Q3-Q4 2008, before “our partners [launch] devices” (plural) become available for retail customers in Q4.  The next round of the Developer Challenge will be announced by the end of the year, with programmers able to submit their applications most likely from the start of 2009.

  • 12 November, 2007 – “Early Look” SDK released
  • January to August, 2008 – Android Developer Challenge I
  • 18 August, 2008 – Android 0.9 SDK beta released
  • September 2008 – additional Android 1.0 (pre) SDK releases made available, as necessary
  • Q3 – Q4 2008 – Android 1.0 SDK release 1 available (first actual 1.0-compatible SDK)
  • Q4 2008 – Android 1.0 devices available at retail
  • Q4 2008 – Source code released
  • Q4 2008 – Key Announcement on Android Developer Challenge II

Google are saying that the current v0.9 beta is not guaranteed to be compatible with production Android devices, but that anything coded with the upcoming Android 1.0 SDK, release 1, will be.
