Blank warning msg after build

Every time I try to build even the simplest watch face, at the end, I get a blank warning dialog. The only thing in the dialog box is the exclamation mark and cancel/OK. No idea what the warning is about. Tried on two different machines and a watch face with just the time. I am very familiar with GWD. Has to be something simple. Any ideas?


Could you please share a screenshot of the error along with the exact steps to reproduce your issue?
Thank you.

Same problem.
It appears every time after reaching 100percent trying to build a wf or run on device.
The wf can be completely empty doesn’t matter what components you add including the default images. :grin:


Please report this issue from Connect > Developer Support. Reproduce this issue and then get the log file of WFS. Please share that log file with support request.

The path of the log file is given below:
Windows : C:\Users{User}\AppData\Roaming\watchfacestudio\dump\main
macOS : /Users/User Name/Library/Application Support/watchfacestudio/dump/main

Thank you.

Hi Jeff,

There are other reports now of the blank message after a build. The team is still investigating what is causing it but a solution is to just quit WFS and restart it. Apparently they build fine after that. If you can duplicate this regularly respond to the bug report ticket and I or Jakia can follow up with you in that system so you won’t need to divulge any information publicly.

I’m having this same issue as well. I sent my log file in already. How long does it normally take to get an answer?

What about uninstalling and installing the program again?

This is such a big headache compared to using Galaxy Watch Face for galaxy 3 watch. I bought the new 4 watch for my girlfriend and made a really nice face for it and can’t get it to build and run on her watch because of the error message.

Really need to know what is the cause of this problem please.

Hi rossperry97,
Welcome to the Samsung Developer Community.

Could you please check if the issue remains after re-setting the “Location” in Build dialog?
The default path is {workspace}\build{project name}.

Please let us know the result.

Thank you.

Hey Jakia
Yes the bug remains I still can’t get this to build and run. The same box comes up. I’ve tried everything above in this thread. Uninstalled/reinstalled and nothing. Reset location and keystore and nothing. Just keep getting the same warning blank box.

Really wanna get this working, please help us.

Thank You

HI Ross,

Try generating a new key, another user had the same issue and it was resolved when he generated new a new key in WFS.

Hope this helps,

I’ve done that but I still get the same blank warning box. I’ve even shut down the program restarted but still the same thing.

I even uninstalled the newest version and went back to an older build, same problem.

I can duplicate this 100% of the time when the Project’s Location (not the keystore location) is invalid. But there could be another reason that is an issue.

The log for WFS is in
you can open that with notepad or any text editor. scroll down the the very end and read the last error. If you can’t tell what the issue is create a support request and include the log file.
When you do ask that Ron be copied on the report.

If I’m looking at this correctly the keystore is the issue?
