Question

I m seeing a weird issue that I m thinking might be a bug I have some logic to determine the Window Size Class that I took from one of the Android Developer Channel YouTube videos I m seeing that the first couple times I change the orientation of my device it seems to not be updating `LocalConfiguraiton current` If I remove the orientation entry from the android config changes field in my manifest then it works every time but with that in there it will not update the first couple times then it ll work after that Code in thread

For reference I have this function that I took from the YouTube video on handling different screen sizes ``` Composable fun Activity rememberWindowSizeClass WindowSize val configuration = LocalConfiguration current val windowMetrics = remember configuration Timber i Recalculating window metrics WindowMetricsCalculator getOrCreate computeCurrentWindowMetrics this val windowDpSize = with LocalDensity current windowMetrics bounds toComposeRect size toDpSize Timber i Screen size w=$ windowDpSize width h=$ windowDpSize height return when windowDpSize width lt 600 dp gt WindowSize SMALL windowDpSize width lt 840 dp gt WindowSize MEDIUM else gt WindowSize LARGE ```

My expectation is that the call to LocalConfiguration current should result in a recomposition upon orientation change and the remember block would have a new key so it would recalculate the metrics

Joseph Hawkes-Cates · Answer

When I test the first 2 orientation changes do not recalculate the WindowMetrics and so the logic still uses the measurements from before the device was rotated After that it seems to recalculate upon orientation change as expected

As I said at the top of the thread if I remove orientation from the android config list for my activity then it works every time as I expect it to

I ran your code using `println`s and it worked for me Pixel 4a in emulator Compose 1 2 0 alpha02 androidx window 1 0 0 AS Chipmunk Beta 1 ``` Composable fun Activity SlackOrientation val configuration = LocalConfiguration current val windowMetrics = remember configuration println Recalculating window metrics WindowMetricsCalculator getOrCreate computeCurrentWindowMetrics this val windowDpSize = with LocalDensity current windowMetrics bounds toComposeRect size toDpSize println Screen size w=$ windowDpSize width h=$ windowDpSize height when windowDpSize width lt 600 dp gt println SMALL windowDpSize width lt 840 dp gt println MEDIUM else gt println LARGE ``` Here are the messages ```Startup Recalculating window metrics Screen size w=392 72726 dp h=850 9091 dp SMALL Screen size w=392 72726 dp h=850 9091 dp SMALL Rotate Recalculating window metrics Screen size w=850 9091 dp h=392 72726 dp LARGE Rotate back Recalculating window metrics Screen size w=392 72726 dp h=850 9091 dp SMALL``` That s with `android configChanges= colorMode|density|fontScale|keyboard|keyboardHidden|layoutDirection|locale|mcc|mnc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|touchscreen|uiMode gt ` With that line deleted it also works but rotate and rotate back each repeat the last two lines like for startup

Huh interesting Thanks for trying it out I ran it on a Nexus 9 emulator on Android 11 and my Pixel 6 phone on Android 12 and it wouldn t redo the calculation the first 2 times on either I m on AS Bumblebee and compose 1 1 0 rc3 though so maybe the difference is one of those things

I should also mention my emulator was running Android 11

Joseph Hawkes-Cates · Answer

Yeah I still see the issue on my Pixel 6 after trying out compose 1 2 0 alpha02

I m also seeing images not update when switching from dark mode to light mode

I see the same as you using the Resizable API 32 emulator there is no Pixel 6 emulator With the line in the manifest these are the messages ```Startup Recalculating window metrics Screen size w=411 42856 dp h=891 4286 dp SMALL Screen size w=411 42856 dp h=891 4286 dp SMALL Rotate Screen size w=411 42856 dp h=891 4286 dp SMALL Rotate back Recalculating window metrics Screen size w=411 42856 dp h=891 4286 dp SMALL Rotate Recalculating window metrics Screen size w=891 4286 dp h=411 42856 dp LARGE Rotate back Recalculating window metrics Screen size w=411 42856 dp h=891 4286 dp SMALL``` without the line in the manifest it works That would seem like a bug

I also see that if you print `configuration orientation` it will change appropriately on the first rotate i e it will be 2 landscape even though you detect it as SMALL

Also `BoxWithConstraints` works swapping `maxWidth` and `maxHeight` on the first rotation
