Simple scenario,
I have a vector drawable in my res folder, which I wish to access in a Compose Preview. Actually, it is a Canvas that draws the vector, and so, I use a painter (a vector painter, to be precise). This is the method used
@Preview
@Composable
fun PreviewTesting() {
val painter = rememberVectorPainter(image = ImageVector.vectorResource(id = R.drawable.example))
Canvas(modifier = Modifier.fillMaxSize()){
with(painter) {
draw(Size(100f, 100f))
}
}
}
This produces a ResourceNotFoundException in the Preview Tab, under the category of a 'Render Problem'. The logs are as follows:
It worked somehow now, without any efforts whatsoever, but the logs included something close to ResourceFoundException : Cannot find the resource(0xFFVscjiwoxxxxx)
The second method I tried was
rememberVectorPainter(image = ImageVector.vectorResource(theme = null, res = resources, id = R.drawable.example))
This produces these logs (error-ful)
java.lang.NullPointerException
