Android could not resolv unqualified hostname

Android is unable by "Design" to resolved unqualified hostname.
Google don't want give a workaroud or fix it...

For Google it's not a bug but a functionnality (to force the used of Google online services...)

So, Android can not resolve "ocsinventory-ng"...
But it can resolve "ocsinventory-ng.local", "ocsinventory-ng.server.company", "ocsinventory-ng.com"...

So when all these conditions are met:
 - you don't use rooted device (to modify /etc/resolv.conf)
 - you don't have MDM Server (because it's to expensive or you want an internal server and not an online solution)
 - your users remove OCS agent from their device...(reset of the device or think you spy them)
 - all your device are registred online to Google
When you force install of ocsinventory trough Google play store... OCSinventory Agent could not contact server...

Because:
 - automatic report is not enabled by default
 - the default url is not a FQDN adress (http://ocsinventory-ng/xxx instead of http://ocsinventory-ng.local/xxx).

Why use .local by default ?
Because it's generic dns suffix use only for internal purpose (it's the default extension on MacOSX for example).
