This Xposed module patches the Mi Fitness application (com.xiaomi.wearable) to work around a bug
where it will fail to list your devices.
Xiaomi uses the Android Room library for handling storage; however, their implementation (as of
version 3.5.1i) has a bug where they access it too early. This means that when Room internally
tries to get the package name, it fails because it couldn't find the application context. This
patch catches this and returns the context it has (which happens to be a partially initialized
Application) to work around the issue.
The relevant stack looks something like:
