You might remember a couple of weeks ago when Google gave developers a heads up about changes to KitKat that might cause problems for SMS apps. At the time, we knew that this only meant there would be a single app in charge of writing to the database, while all of the others would...well, that part wasn't really defined. Today, one in a series of developer videos gave us a little clarification on what it means to be a default app, and what it means for the rest of them.
In a post on the Android Developers Blog earlier today, Google has given us yet another indicator of upcoming changes to the Android platform. When KitKat launches, it will finally introduce a public API for the last remaining functions texting apps could not achieve without diving into private APIs. Developers are often advised to stay away from private APIs since they can change with each new version and may not be kept consistent across different OEMs.
