As you know, Huawei was revoked the Android license. Do you have to expect the same with Xiaomi, or is there no reason for that?
No.
So far there are no indications. Have a Mi Mix 2s everything is great. Do not expect any changes in the future.
You can't withdraw licenses that do not exist.
Android is Open Source… So Royalty Free.
For what it's about, the Google licenses to preinstall Google Apps.
Moreover, this is the trade embargo against Huawei for alleged espionage against the US through network technologies.
Huawei is the world leader in networking technology.
Xiaomi has nothing to do with anything like that.
That means, you can easily install and use the Google services (Playstore, Maps, Youtube etc.)?
I do not understand the question. There's no trade embargo against Xiaomi.
As a result, Xiaomi has all Google Apps. At least with the devices coming to Europe.
Definitely not.
Xiaomi's main market is China. And that's where all Google services are blocked anyway, which is why Xiaomi operates its own appstore, which makes up a large part of Xiaomi's profits. (You can find an interesting video here:
The devices in Germany (global Rome) are only recently available, and adapted only to the Western market. In the past (I still know the times) it was like you ordered Xiaomis in China and just installed the Playstore over it. Everything went wonderfully.
