Can confirm it, it is not working

[helin24]

What operating system are you two using? This occurs when JCEF is not supported and I've mostly heard of this happening on Linux. However, I think we should be catching this error and offering an option to open DevTools in the browser.

It doesn’t work

• macOS 14.2.1 (intel)
• plugin 77.1.2
• Android Studio 2023.1.1

There is a workaround if you change the Boot Runtime for the IDE to one with JCEF:

• Open the Navigate -> "Search everywhere" (or search icon top right)
• Search for "Choose Boot Java Runtime for the IDE..."
• Select a runtime that has "with JCEF" in its name
• Restart IDE
  The flutter inspector now should show up.

The problem is fixed. Thanks a lot

it stops my virtual VM devices from working

Inspector says no error but it is getting not loaded, also older version's with JCEF under "more" are slowing down extremely Android Studio. Mac m1. Flutter plugin 77.1.2, AS Hedgehog | 2023.1.1

Thanks @patrickseiter-hkcsoftware ! This is what we're recommending as well. This stackoverflow link provides a bit more context: https://stackoverflow.com/questions/69171807/markdown-editor-and-preview-not-working-in-android-studio

@sadjadtalakoob74 can you describe what VM devices you're using and what (if any) error messages you see as a result? I wonder if there are other JREs that would allow both the embedded inspector and your devices to work.

@GemsAlex this sounds like a separate issue. Are you able to reproduce this and send me a log (helinx@google.com)? Go to Help > Show log in finder and find idea.log.

[GemsAlex]

@helin24 Can't reproduce the slow down. Anyway now I am getting an idea error after few sec open flutter inspector :
GPU process restarts too many times and seems to be unstable. Try to restart IDE or disable GPU acceleration completely
