APK (= Android Package) is the installation file for an Android app. This is required if you cannot download the Sdui app from the Google Play Store.
This is also the case for Huawei users whose devices were manufactured from summer 2019 and do not have access to the Google Play Store.
You can download the latest version of the Sdui app here:
