Hello,

I'm only a little familiar with Power Apps. Is your app a mobile app or a web app?

This link lists out the alternatives.

The primary recommended alternative for the Google Fit REST API is Health Connect.

If your app does not work on Android mobile devices, you can also consider the Fitbit Web API.

In the above code, is className defined as a string literal in the same method, or is it an input to the method? Unless it is defined as a string literal in the same method, the above code is only guaranteed to work if there is a keep rule that specifies that className is instantiated by reflection.

It's s a string param. Can you then give the proper minimal rule they should embed?

The interface is :

public interface ActionCallback {
    /**
     * Performs the work associated with this action. Called when the action is triggered.
     *
     * @param context the calling context
     * @param glanceId the [GlanceId] that triggered this action
     * @param parameters the parameters associated with the action
     */
    suspend fun onRun(
        context: Context,
        glanceId: GlanceId,
        parameters: ActionParameters
    )
}

From what I can see, I would expect that -keep,allowobfuscation,allowshrinking class * implements androidx.glance.appwidget.action.ActionCallback { void <init>(); } should work.

Seems to work, Glance team have all needed to embed the rules now.

For my culture why is the void <init>(); needed? Should not keeping the class and having some usage of the interface in code be enough for R8 to suppose it's instantiated?

And more generally maybe there should be an annotation for this use case? Like there @DoNotInline in androidx.annotation ?

zak should investigate this further, to see if we can add a more general keep configuration

Updated to R8 3.3-18 dev and the issue is back

java.lang.InstantiationException: java.lang.Class<yb.a> cannot be instantiated

That file that expand the Glance interface

.class public interface abstract Lb3/a;
.super Ljava/lang/Object;
.source "SourceFile"

.class public abstract Lyb/a;
.super Ljava/lang/Object;
.source "SourceFile"

The glance interface is now changed to :

# interfaces
.implements Lb3/a;

That with the previously validated rule:

### Glance:
-keep,allowobfuscation,allowshrinking class * implements androidx.glance.appwidget.action.ActionCallback { void <init>(); }

Thanks for reporting back. Can you give some more details on the structure of class yb/a? Is it missing the constructor, or is there some other error leading to the failing instantiation? Is there more information in the exception on why the instantiation failed?

This is the exact same class as OP (ButtonAction)

Using ugly -keep class * implements androidx.glance.appwidget.action.ActionCallback does fix this.
