Fix NoSuchMethodError: WindowMetrics.getDensity() crash on launch

[StylianosGakis]

Problem

The app crashes on launch on some Android 14 devices, before the first frame:

Fatal Exception: java.lang.NoSuchMethodError: No virtual method getDensity()F
in class Landroid/view/WindowMetrics;
  at androidx.window.layout.util.DensityCompatHelperApi34Impl.density(DensityCompatHelper.kt:64)
  at androidx.window.layout.WindowMetricsCalculatorCompat.computeCurrentWindowMetrics(...)
  at androidx.compose.material3.windowsizeclass.calculateWindowSizeClass(AndroidWindowSizeClass_android.kt:44)
  at com.hedvig.android.app.MainActivity.onCreate$lambda$4$0(MainActivity.java:253)

MainActivity derived the window size class with material3's calculateWindowSizeClass(activity). That routes through androidx.window's WindowMetricsCalculator, which calls WindowMetrics.getDensity(). That method is not present on some Android 14 platform builds, so the call links to nothing at runtime and throws NoSuchMethodError during initial composition. The library gates the call at API 34 but relies on a method only present in a later Android 14 revision.

androidx.window:window:1.5.0 is pulled in transitively via material3-window-size-class:1.5.0-alpha17 (from the jetbrains-material3 = 1.11.0-alpha07 stack).

Fix

Compute the WindowSizeClass from Configuration (screenWidthDp / screenHeightDp) via WindowSizeClass.calculateFromSize, which reads Resources.getConfiguration() and never touches androidx.window.

A guard comment at the call site documents why we avoid both calculateWindowSizeClass(activity) and LocalWindowInfo.containerSize (the latter routes through the same androidx.window density path in Compose UI 1.11.4).

Verification

Built the R8-minified staging APK and inspected the shrunk dex + mapping.txt:

• material3's AndroidWindowSizeClass_androidKt (the crashing path) is stripped from the shipped app: the reported crash cannot recur.
• The only residual WindowMetrics.getDensity() reference is Compose UI's lazy LocalWindowInfo.containerSize path. It is computed only on read, and no app code reads containerSize (custom navigation, no material3 adaptive APIs), so it never executes.

Scope note

This removes the live trigger of the buggy androidx.window code without pinning the dependency. If the app later adopts Compose adaptive-layout APIs that read containerSize, the underlying androidx.window bug would resurface and pinning androidx.window would then be warranted.
