Please complete the following information:

  • Library Version: 0.2.3
  • Affected Device(s): Android 8.1 and older versions

Describe the Bug:

ANR happens when user navigates to the screen that uses the cloudy modifier. Logs show that it happens when creating blurred bitmap with runBlocking.

Cloudy/cloudy/src/main/kotlin/com/skydoves/cloudy/CloudyModifierNode.kt

Line 127 in 2ef5a96

val blurredBitmap: Bitmap = runBlocking(Dispatchers.IO) {

Compose version: bom:2024.09.03

I see hundreds of ANR logs in Google Play Android Vitals.

Log details:

The frame drops and ANRs issues happen because of this.
One way to fix this would be moving the blur calculations to a background thread, and stop blocking the main thread. While this would create a slight delay where the blurred image might be a few frames behind the actual content, it would at least prevent the app from freezing or dropping frames.
Hopefully, the library maintainer will take this into account and address these issues in future releases. 🙂

Hey @desugar-64, thank you for pointing out the issue! Would you be interested in contributing to the project as well? If you’d like to collaborate further, feel free to let me know—I’d be happy to discuss more opportunities!

@skydoves It’s quite intriguing. I’ve never contributed to open source projects before and I notice there’s no contributing guide in your repository. How does this process usually work? I don’t have much personal time available, but I’d like to help if I can, even in small ways.

Thank you so much for your interest! The process is simple: fork the repository, create a branch, work on your changes, and then submit a PR—that’s it. Your efforts, even just suggesting an idea or discussions, are already a valuable contribution. when you have a moment, feel free to turn your ideas into code :)

+1 I am experiencing anr on an android 8.0 device.

I'm also experiencing this issue on devices running Android 8.1 and below.

It looks like the use of runBlocking in CloudyModifierNode is the issue.
