The application would retrieve row(s) from a database and display some textual data from the rows as well as an image associated with the record that will be stored on the SD card.

On the Nexus One (at least in 2.1-update1, and I think in 2.1), there is a setting under Sound & Display: "Pulse notification light".

I want to set this programmatically without user interaction, in order to make a Loc...
