What are the requirements of Image Kit on mobile devices and software? In principle, Huawei devices running Android 8.0 or later supports Image Kit if HMS Core (APK) 4.0.2.300 or later has been installed. If the fallback-SDK is used, this requirement can be ignored.
This is what huawei's site claims so it requires api 26, but does the fallback-SDK work on api 21 or the fallback means it works on devices without HMS?
