camerax sample: Unresolved reference: WindowManager

Question

I'm trying to compile the sample cameraxbasic but I get this error: Unresolved reference: WindowManager I checked gradle files and there is that dependency.

In particolar I get the error from CameraFragment.kt import androidx.window.WindowManager — Marco Piccirilli, Apr 13 '22 at 18:19
I have exactly the same problem. Did you solve it? Help would be very much appreciated. — Cyrill, Apr 15 '22 at 23:22

I reviewed the library change log at https://developer.android.com/jetpack/androidx/releases/window and adjusted the sample with following these changes to make it work. Hope this helps!

use implementation "androidx.window:window:1.1.0-alpha01"
replace WindowManager with WindowInfoTracker
replace WindowManager(context) with WindowInfoTracker.getOrCreate(view.context)
replace windowManager.getCurrentWindowMetrics().bounds with WindowMetricsCalculator.getOrCreate().computeCurrentWindowMetrics(requireActivity()).bounds

Wow! Thanks! Would be nice if CameraXBasic team would update — delicatesan, Oct 14 '22 at 23:22

funny how Microsoft has a guide on Window Manager here:

https://learn.microsoft.com/en-us/dual-screen/android/jetpack/window-manager/?tabs=views

guide says which packages to include and how to use in the code, specifically to answer the question:

windowInfoTracker = WindowInfoTracker.getOrCreate(this@MainActivity)

while android has no official guide and a broken use case at the official github CameraX sample https://github.com/android/camera-samples/tree/master/CameraXBasic
