Decision

Fixed — this is a real crash affecting users who open the Health Connect permissions rationale screen on Android.

Root Cause

The AppCompatTheme style used Theme.AppCompat.Light.DarkActionBar as its parent, which provides a window-decor action bar. However, HealthPermissionsRationaleActivity.onCreate() also calls setSupportActionBar(toolbar) with a Toolbar widget from the layout. Android throws IllegalStateException because you cannot set a support action bar when the theme already supplies one via the window decor. The fix is to use NoActionBar as the parent theme so the custom Toolbar widget is used instead.

Test plan

• Build Android APK and launch the Health Connect permissions rationale screen
• Verify the toolbar displays correctly with back navigation and title
