Appologies in advance, I'm using Google translate for your question.
Which Huawei device are you using? Most newer devices will be ARM V8 (64-bit). The EMUI OS is supported on ARM V7 (32-bit), x86 (32-bit) and ARM V8 (64-bit) so I'm not sure which option you need. Please select the appropriate download from the Survey123 Resources page depending on your specific Huawei device.
The download itself will be a .exe file. You will need to run this on a Windows machine, it will prompt you to accept the license agreement and then ask you for a location to extract the .apk file. This .apk file can then be sideloaded to your device and installed as normal.
Hope this helps,
