I need to reinstall Google Camera, and I tried to remove it via Settings -> Applications. Everything went fine, but when I tried to install it back via Play Store, it said:
Unknown error code during application install: -505.
I've then attempted to install it's APK via ADB. It showed the error INSTALL_FAILED_ALREADY_EXISTS. But I'm pretty sure it's removed, I've checked /system/app, /data/app, and /data/data for any residual files, but there's none.
Installing APK with -r key yields INSTALL_FAILED_UPDATE_INCOMPATIBLE.
Package manager pm list packages doesn't list Google Camera, which is only logical, since it's removed. But then how could it "already exist"? I wonder what to do and how to bring Google Camera back.
pm uninstall <package_name>to get rid of potential remains – and also check your SD card (yes, the internal, I know it's a Nex) for such. – Izzy Jul 28 '15 at 16:29pm list packagesthat doesn't list Google Camera). – CubiX Jul 28 '15 at 17:52
