How to read current screen orientation on Android?

Question

I would like to read current screen orientation on Android using Jetpack Compose.

I already tried following in a @Composable:

val o = LocalActivity.current.requestedOrientation

val o = LocalContext.current.display.rotation

val o = LocalActivity.current.resources.configuration.orientation

but in vain.

Log.d("Orientation", "The Orientation $o")

Everytime, I rotate the orientation, log outputs on these remain the same. So they do not seem to change.

How can I read the screen orientation?

"Everytime, I rotate the orientation, log outputs on these remain the same" -- you might want to expand your [mcve] to show when and how you are logging these values. Beyond that, though, bear in mind that with split screen, freeform multi-window (Chrome OS, Samsung DeX, etc.), foldables, and the changes coming in Android 12L, that "orientation" is becoming an obsolete concept. — CommonsWare, Nov 29 '21 at 00:46

You could override onConfigurationChanged(Configuration) method of your activity.

To get this method called you also need to specify the changing in android:configChanges attribute in your manifest file.

See what and how to specify, kindly check this docs.

You can get it from BoxWithConstraints and compare the width with the height.

A simple example:

class MainActivity : ComponentActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContent {
          //Our composable that gets the screen orientation
            BoxWithConstraints {
                val mode = remember { mutableStateOf("") }
                mode.value = if (maxWidth < maxHeight) "Portrait" else "Landscape"
                Text(text = "Now it is in ${mode.value} mode")
            }
        }
    }
}

orientation is not just Portrait or Landscape. It can be 0, 90, 180, 270 degree rotation. There any way to determine the degree? – Tapa Save Oct 03 '22 at 03:08
