Google yesterday announced that it is working on a new technique, File-by-File technique, which will help reduce the size of the ever annoying app updates.
It has been a long persistent problem that many Android users have been complaining about. However, To put it in numbers, with this new technique, the search engine giant will be able to reduce the weight of an app between 65 percent to 90 percent of the original app size.
To explain this technique, Google compares the uncompressed versions of both the old and new file and identify the changes required with the bsdiff algorithm. Next, it decompresses the old file, applies the delta (patch) to the uncompressed content and then recompresses the new file.
“In doing so, we need to make sure that the APK on your device is a perfect match, byte for byte, to the one on the Play Store,” â€“ read the blog post from Google. Previously, Google developed the bsdiff algorithm with Colin Percival at the heart of it.
In a related development , Google has also finally rolled out the ‘Upcoming’ tab feature to Google Search or Google App for Android. Previously, there use to be only a single feed for all the information displayed in the app. Now, the whole set of information is divided into Feed and Upcoming. ‘Feed’ will display information like emails, weather, news etc. whereas ‘Upcoming’ will display personalised information like upcoming events, upcoming bookings, travel time to commute, package delivery tracking etc.
Moreover, selected Google Now card including the Weather Card has now been shrunk down, removing the whole week’s forecast, to make more space. Further, Google will still continue to prioritise the position of these cards based on what it thinks is important for users based on their usage pattern.
