### Obtaining apk

### Signing into account

This process for Xiaomi login is pretty unintuitive, so make sure to read this first!

1) Install the apk, run it and manually give it permission for storage (only needed if you plan to fetch aGPS).

- Once you press Sign in, your browser will either warn you or this gets you to a blank page. In any case, the url starts with `hm.xiaomi.com/watch.do?...`. You must copy this URL:

- Go back to Huafetcher and paste the URL into the URL result field by using the Paste button.
