Apk

In the past day or so, I've been noticing these "Package file is invalid" errors on my Android devices while trying to upgrade or install certain packages from the Play Store. A bit of searching revealed that many others are having this problem, and various home remedies abound for trying to fix it, such as clearing the Play Store's app cache. Unfortunately, while these remedies may have worked for past problems that led to this error message being displayed, they are useless when trying to fix the issue people are experiencing this weekend.
