I have checked this android 5.0 lollipop app install shows Unknown error code during application install: "-505". But it doesn't seem to address my case as I dont use multiuser env.
I have an app in the playstore which worked fine on my nexus 4(4.4.x) till i upgraded to lollipop and it showed this error every time i tried to install it from playstore(It installs fine if I run it via adb).
Can't understand why I might be facing this issue, neither is there any other reference to this error code. Any help is appreciated.
