Google Play Debuts "Smart Apps"
As part of a broader overhaul of its Play Store, Google has enabled so-called “smart app updates,” Android Police reports. “Normally, when an update to an application comes out,
the Play Store downloads it in full, which with large apps and slow connections can get quite painful,” the blog explains. With smart apps, however, “only the incremental difference
(a.k.a. the delta) between the old and new apks [sic] would be sent over the wire, thereby saving huge amounts of data for both Google and Play Store users.”
