Any Proguard rules should I need to add for health Connect API?

Aug. 3, 2022:

As of version 1.0.0-alpha03, this has been fixed on the library's end.

Links :

• https://developer.android.com/jetpack/androidx/releases/health#health-connect-client-1.0.0-alpha03
• https://android-review.googlesource.com/c/platform/frameworks/support/+/2153498/2/health/health-connect-client/proguard-rules.pro

For the meantime time, you can add these rules into your proguard file:

-keep public class androidx.health.** {
  public protected private *;
}
-dontwarn androidx.health.**

It is quite overarching to ignore the entire lib at the moment, but at least it gets your project to build under release.
