APK being Cached after Uninstall App on Android Lollipop


Last time, I got a problem with Nexus 5 with Android Lollipop. I developed an application on the devices and tried uninstalled it. At this point, there was no problem, the app didn’t appear on launcher anymore. But, when I tried to install from Google Play Store, the download process was very fast. The app version was not Google Play Store version, but the developed version. I thought that *.apk was cached somewhere in the device.

Inspect App using ES File Explorer

I uninstalled the app once more. I ran ES File Explorer, open Homepage tab, and click APP.

I saw that our develop version still appear in that list. I tried to open it, but couldn’t. So I checked the Properties of the app. I see that the app already uninstalled.

Solutions: Uninstall for all users

Android Lollipop on some devices can have multiple users. On Nexus 5, by default, there are two users (primary user and guest).

When an app is deployed (by developer) to the device, it will be installed on all users. So, to remove app from all users, in App infoclick on more menu (vertical ellipsis) and then Uninstall for all users.

After this, the app will be removed from your devices. If you reinstall from Google Play Store, it will download the store version.
