Android has cryptography in it for app signing and secure logins and such. Crypto is a real sensitive subject for export, even fairly standard implementations like what Android has. I'll bet that once the question is raised with government officials they will say that Google licensing crypto to (or just trusting certs from) Huawei is a hard no.
It would be real hard to make the Play store useful if you take away its main feature of getting trusted versions of apps. Ditto for most of Google's other products in Android.
Edit: For those of you who disagree with me, check out what happens now that Huawei is on the entity list (https://www.bis.doc.gov/index.php/policy-guidance/lists-of-p...). Most notable is that they are now subject to "license requirements are independent of, and in addition to, license requirements imposed elsewhere in the EAR." Even if Android is deemed no license required (NLR) to every other person in the world, the US government can still prohibit Google from licensing Android to Huawei. If you don't think that the government would use a petty excuse such as [easily available] crypto to deny the license, then you obviously haven't dealt with the government enough. The US government was treating crypto the same as nuclear technology up until the year 2000, and they would still prefer if US companies didn't give out source code on the internet. This isn't a bunch of forward thinking Silicon Valley types making the judgement call, it's a bunch of bureaucrats in suits that don't understand how the internet works.
Just because it's publicly available doesn't mean the US government won't try to embargo it. The government does silly things all the time.
The book "No Easy Day" became a New York Times best seller as soon as it was published (it's written by the SEAL that allegedly shot Osama bin Laden). The Department of Defense threatened to revoke the security clearances of military members that read the book because it contained classified details. It took a few weeks before they walked back their threats, because somehow nobody at the top realized how stupid it was to revoke security clearances over reading a bestselling public book.
