I am experiencing a problem with Google Play in my Android phone. When I download new apps from the Play Store, it completes 100% and then shows me an error:
(unknown Error code during application install:''919'')
I was getting the same thing when updating apps. Tried over wifi and service provider network same thing was not with just one app all apps that were set to up date even google apps. I cleared the cache and it seems to be working fine now settings/app manager/googleplaystore/clear cache
I Know its already answered but this answer may help to fix it and help someone. source link
