Jetpack Compose. Offset is unspecified on Redmi devices

Question

In my project I get a lot of those exceptions:

Fatal Exception: java.lang.IllegalStateException
Offset is unspecified

These exceptions only appear on Redmi devices (tablets and handheld). This issue is present from version 1.1.0 to the latest 1.2.0-beta03 of Jetpack Compose, so changing version is not an option.

There is a full stacktrace:

Anybody faced it?

Answer 1

I got this issue when i change touch area of a Composable dynamically when changing scale via Modifier.graphicsLayer{} and i also use Offset.Unspecified to not draw on Canvas initially for drawing apps.

If the issue is something happens on small region and negligible use

if(offset != Offset.Unspecified) {
    xCoor = offset.x
    yCoor = offset.y
   // or do drawing with offset here for valid values

If it's a behavior that never returns any value but Offset.Unspecified you should open an issue for it.

Answer 2

I used to get this exception when my offset parameters are not a number.
Make sure that your Offset parameters are number.

Here is how you can check if it is a number :

if(offsetX.isNaN().not()){
//handle your code here
}
