Cannot add google account (It is not in the list of available account) I bought the tablets from China, and if I want to add Google account (from Settings.Account.AddAccount) ther is no google account in the list.. There is only

Corporate

POP3

tablet:

Android 4.4.2

kernel 3 April 67

Build ALPS.KK1.MP1.V2.11

and on tablet are no applications from Google (NO "Gmail", "Account Manager Google" and "Google Services Framework")
It looks as if not installed (or forbidden) Google applications from the producer.
Manufacturers must certify their devices with Google in order to have the Google Apps pre-installed1. Obviously that wasn't done for your device. So you have to either install GApps manually (follow the previous link for details) – or use the chance a "Google free" device gives you and install an open source alternative like miroG.
