well,
the worst and retarded developer support.
this is not the first time. if you canât maintain a product, then better shut it down.
my flutter workspace just got disappeared.
2 months of development (last commited 2 months ago to git repo). where it gone ? no one knows.
wasnât expecting this from a googleâs product.
if anyone reading this. just switch to some alternative like codespace or just develop locally,
Edit: I was just frustrated, lol

No, no devices are available, and the emulator is not running. When will this issue be resolved?
Hi everyone, sorry for the late reply on this issue. Taking a look now, but would like some help. Can I get some info on the following please?
- what version of flutter are you using
- Is this an old workspace or a new workspace
- browser
- details on error messages (appreciate the screenshots already posted).
I am not able to run my android even after first creating a workspace. You would think it would work fresh out the box, right? @Alex
Hi! I just deleted and created a new workspace and got same error:

I think this is a general issue that many developers are experiencing, and based on my research, I havenât found anyone who has managed to solve it. I tried resetting, reopening the environment, and modifying the dev.nix file, but it didnât work. Hopefully, the IDX developers will fix this issue soon.
We are actively working on a fix for this. Thanks for flagging this and sharing the additional details that Alex called out.

Hi folks, wanted to give an update on the emulator issue.
We rolled out a fix, which should get the emulator up and running. The emulator is complicated and we suspect there will still be issues (ex: ndk version mismatches), but it should at least be up.
I personally see some issues where the emulator says the the UI is not responding, but a hard restart should fix that.
Wanted to apologize about the breakage, and thanks for reporting. Please let us know if the emulator still isnât up.

Hi Alex,
the emulator now starts but it always takes a long time to load and the System UI not responding prompt, which covers the Splash screen that I would like to verify, disappears only after a Hard Restart that does not reload the Splash Screen. The emulator itself then remains slow and in many situations not usable for a real verification in usual situations for the user (I am a terrible mobile phone user and I easily create unexpected situations).
For now I have deactivated the emulator again and use the Web preview sized appropriately to fine-tune the design and logic, if one day, as I hope, IDX were to go into production, the Android and iOS emulators will have to be fast, reliable and consistent with their respective native environments, alternatively, and perhaps it would be the best solution, IDX should allow testing on a locally connected device.

Thank you for your hard work! Looking forward to the fix and getting back to full app development.
Great! Will test out now
Hello,
Iâve been having emulator running issues for quite some time now. I havenât been able to work on my project for the past few weeks and when I came back to it today it said Dart had been updated (if I remember correctly).
Now not only the emulator is not running anymore, but I also get an error message when trying to build the APK to test it on my phone.
The error message (which breaks the build, even though itâs shown as a Warning) is as follows: Warning: License for package NDK (Side by side) 26.3.11579264 not accepted.
When checking in /home/user/android-sdk/ndk, I find a symbolic link from 23.1.7779620 to ndk-bundle in /nix/store/âŚ-android-sdk-ndk-23.1.7779620/libexec/android-sdk/.
It thus seems thereâs also a version problem for NDK, apparently 26.3.11579264 is expected and my Project IDX environment seems to have 23.1.7779620.
Not sure this is related to the initial Android preview not working problem, but since you mentioned NDK version mismatches related to the fix you rolled out, I thought it might be related.
How can I solve this problem?
