Yes, I'm as well looking for an InApp Billing ANE for Huawei's AppGallery (what is the equivalent to Android's Play Store). Sure, I do not awaite noticable revenue for the next time but never underestimate the Chinese people! 🙂 Their hardware is convincing more and more people outside of China and Trump's Huawei ban accelerates all. One of the few golden rules in app programming is still that you must be one of the first on a new market to have a chance for a great growth. 🙂
But I didn't find an ANE.
By the way I registered as a developer at Huawei but I was not asked to pay 80 USD. May be they ask later.
Funny, by the way, that an uploaded APK file must be reviewed first. That's more Apple stuff I think. 😄
