Compose: Software rendering doesn't support hardware bitmaps

[yschimke]

Raising, because I haven't seen this with Coil and Compose before.

This is with Coil 2.2.2 (it's from a prod report, so possibly was older version)

Other reports like #31 seem to be View based.

My expectation is that by default Coil, will choose the right hardware more. Disabling presumably fixes this, but as it's working in almost all cases, that seems sub-optimal.

Should this be possible with Coil and Compose?

@yschimke Sorry for the delayed response! Coil ideally should automatically disable hardware bitmaps, however there are some edge cases where it's not possible with 100% certainty. A few questions:

Are you adding AndroidComposeView nested inside another view (i.e. not using setContent inside an Activity)?
Are you seeing this on a specific device or API version?

My hypothesis is we're probably reaching this line and the view isn't attached yet. However, considering it only happens occasionally it could be a device-specific issue in which case we'd want to add it to the blocklist.

Let's close, it was from a prod report, so I don't know the code path

I've seen this issue once now @colinrtwhite and yes, I'm using an androidx.compose.ui.platform.ComposeView.

I'm seeing this issue on a OnePlus 6T.

Can I gracefully ignore this error? I'm now setting 'allowHardware' to false:

val request = ImageRequest.Builder(LocalContext.current).data(image).allowHardware(false).build()
AsyncImage(model = request,
    contentDescription = null,
    contentScale = ContentScale.FillHeight,
...
)
