A recent update to Google’s Play Store Android app that was intended to increase usability and make apps easier browse has had the unintended effect of complicating the experience for some users. The 4.3.10 update contained few major changes, but a number of users reported encountering a bug that delivered a “Package File Invalid” error message during some updates and downloads.
“We’ve received reports that some users are getting ‘Package File Invalid’ while trying to download or update apps,” Google posted on its Support page on August 13. “We’re currently investigating a permanent solution, and there are no workarounds at this time.”
The flaw was marked as “Fixed/Resolved,” suggesting that it may have been a minor issue that has already been handled. Nonetheless, such errors underscore a problem many software vendors encounter.
The recent Play Store update contained no major functionality changes, instead simply adding a “Recently updated” section to the Installed apps page and incorporating a few cosmetic changes, Android Community noted. As a result, vendors should be wary that any changes to their software – however minor – can create new flaws or reintroduce old, incompatible code.
To avoid such issues, developers should scan each update as thoroughly as they would a new release, using tools such as static analysis software and methods like peer code review. Code refactoring tools can also be helpful in combing for lingering, obsolete code that may contain the seeds of threats or bugs down the line.
