Google has created a welcome modification to its Play Store app delivery system that should help to speed up updates and reduce information consumption by making them smaller.
An updated algorithm can cut back the size of updates by as much as 50 % by downloading solely the specified changes to APK files and merging them with existing files – presenting a much more economical system than previously enforced.
For approximately 98 % of app updates from the Play Store, only changes (deltas) to APK files are downloaded and integrated with the present files, reducing the size of updates. we tend to recently extended a delta algorithmic program, bsdiff that additional reduces patches by up to 50 % or additional compared to the previous algorithmic program
Bsdiff is specifically targeted to provide a lot of efficient deltas of native libraries by taking advantage of specific ways that during which compiled native code changes between versions. To be handiest, native libraries should be stored uncompressed (compression interferes with delta algorithms)

Google first rolled out support for delta updates – those which
includes just the change – all the way back is 2012 but the latest algorithm
improve the system quite dramatically.
Google impressive algorithm has been expanded to APK expansionfile – often used for large file like games – for the first time. This addition
can reduce the download size of initial installs by 12 percent, and updates by
65 percent on average.
Application which makes use of uncompressed native libraries will
see the biggest improvement whilst those which have already been compressed can
only expect around five percent decrease.
The number of app updates being pushed out by android developers has
been on a steady rise according to Google and so its great user can grab the
latest version faster than before and use the less data in doing so. To assist
users further, Google will now even report the size of the delta update before
download
