Google Further Shrinks the Size of Android App Updates

Google says it has found and implemented a new way to make app updates on Android smaller. From a report on Engadget: They're introducing a new approach to app updates that promises to radically shrink the size of updates with "file-by-file" patching. The resulting patches tend to be about 65 percent smaller than the app itself, and are sometimes over 90 percent smaller. In the right circumstances, that could make the difference between updating while you're on cellular versus waiting until you find WiFi. The technique revolves around spotting changes in the uncompressed files (that is, when they're not squeezed into a typical app package). Google first decompresses the old and new app versions to determine the changes between files and create a patch. After that, updating is just a matter of unpacking the app on your device, applying changes and compressing it again.
