Google Play App Update: "invalid file" error message (Android)
Don't have the Wikiloc App yet? Get it here!
Do you get an error note indicating that "file is not valid" while updating the App from Google Play?
Try to fix it as follows:
- From Google Play Services, go to Apps
- Clear the cache and the data
- Restart your device
In some cases, just waiting a few days for the App to update will stop giving the error message.
We recommend NOT to uninstall the App. The message usually continues appearing and the problem may be aggravated by not having the App.
