App updates are now half the size on Android
At Google they know very well that there are users who need to get the most out of each of the contracted MB with your mobile operators In addition, to ensure that mobile phones that run with your operating system Android are more fluid, it is convenient to manage smaller size. That is why they have improved the system of Google Play Store updates to reduce to almost a thirdthe size of these files that include news for the different applications installed on the mobileSomething that will expand the possibilities of many users to get news even if they do not have a WiFi nearby network.
To date, Google had made some progress on this issue thanks to the bdsiff algorithm that you implemented a few months ago. Thus, along with his system of downloading only the new parts of the application and not the entire tool, he managed to reduce by a 46% the size of updates A new advance now extends the compression of these files to 65% of the entire application , and as media, finding cases where compression reaches 90 percent
This new technique, which they have called File-by-file or file by file, is able to replace only the really new parts of the application to update it.As Google itself explains on its page for developers, and giving the example of a book that has to be corrected , you don't need to order a whole new book to change a sentence, just update that sentence. The key, in this new system, is that this phrase or application update arrives compressed to consume less data than the rate from Internet and allow updating. Of course, this technique only applies to automatic updates, which are carried out in the backgroundand, generally, when the mobile is connected to WiFi. The rest of the updates, the manuals, continue to occupy the same space.
But not everything is positive in the use of File-by-file And it is that the compression process of the updatescauses installation time to doubleFirst it is necessary to uncompress the patch or update, after that do the proper with the application informationto confirm that everything matches as it should. Once the update is applied, the information is recompressed This process can be accomplished at a rate of one MB per second in modern and powerful terminals, but it can take longer in older mobiles, with a less powerful processor. A cost that must be assumed for a more efficient consumption of MB
With this, automatic updates from the Google Play Store could save between 2 and 13 MB of data, depending on the application. Something that will help users not to be outdated, something that goes beyond a mere improvement to a game or a new function in an app, and that is that there are some tools that require updates to continue working.Thus, with the automatic updates activated, the data rate will not be affected as much. Of course, it is always recommended to use a connection WiFi for updating and downloading applications and games, since it is the most agile way to download and without affecting the user fee.
