This error started appearing in August on some computers with Android 4.2 when trying to download apps from the store Play Store.
Arises from an update of the Google Play August 2013 , apparently the 4.3.10 application. This error occurs randomly and attempt to download or update any application. Some have noticed that if retried during the day, maybe this error afternoon but at night they no longer appears . And though the implementation happens we seek download is completely valid.
In Google you know the error and figure apparently marked as Solved : [# 10230007 ] "Package File Invalid" error when downloading or updating apps, but still no update to fix the problem was launched.
For now it seems there is no definitive solution to the problem , and it is recommended to those who suffer is to reattempt downloading applications at different times of the day to do it. And ALWAYS DOWNLOAD APPLICATIONS USING WIFI, no 3G/4G data networks , and I've read that many users in Colombia , Peru and Ecuador have this problem with Telefónica plans , where they say that their plans are "Navigation " and not Downloads . Something else you might try , is if the home WIFI does not work , go to work, or to the bar , to the house of a relative / friend / partner / neighbor or the nearest place with WIFI , and if it is a WIFI than public and have to ask for the password , even better, and try to see if that connection can download applications ; and discuss if this solved the problem for them too ;)
Meanwhile we still only be aware of application updates Google Play, and clear your cache and data and uninstall updates before updating to the final version , so correct for erroneous data that could be from the previous version .
