Bug? Error while invoking Sdk Manager

[cimperia]

When I invoke B4A Sdk Manager, it always displays this error:
Error Could not find or load main class Dell\AppData\Local\Temp

OS: Windows 10
b4A: 9.30

I believe the error might be caused because the user's folder contains a space. It's located in

C:\Users\userName Dell\

The error is indeed caused by the space in the user's folder. I've temporally changed the folder name to remove the space and no more errors. But, I need to keep the folder name as it was, ie with a space.

Any possibility of a quick fix?

There's the same issue with avd manager.

Use the ready to run SDK for now. The fix requires an update to the IDE.

Please check it again when the next beta is released (it will probably take a few months).

Do you mean this https://www.b4x.com/android/forum/threads/ready-to-run-sdk.99780/ ?

That I should be running sdkmanager.bat from the
command prompt?

No. In most cases you don't need to run anything as it includes the required components.

I did that and the error is still there.

The issue is with B4ASdkManager.b4j.

The fix is passing the Java Option(s) as an array.

I suppose it'll prevent the tokeniser from splitting strings at spaces.

Public Sub SetEnvironment(s As Shell)
    s.SetEnvironmentVariables(CreateMap("JAVA_HOME": FindJava, _
        "JAVA_OPTS[@]": $"-Djava.io.tmpdir=${File.DirTemp}"$))
 
'    s.SetEnvironmentVariables(CreateMap("JAVA_HOME": FindJava, _
'        "JAVA_OPTS": $"-Djava.io.tmpdir=${File.DirTemp}"$))
End Sub

AVD manager is working ok, too.

Interesting solution. I've implemented a different one. Please test it when the next beta is released.

Continuing the discussion here.

- Make sure to use B4ASdkManager.jar that was included in v9.50.
- Run the IDE with logs enabled: https://www.b4x.com/android/forum/posts/50478/
It should print the temp folder. Something like:

TempFolder: C:\Users\H\AppData\Roaming\ANYWHE~1\BASIC4~1\temp

Do you see it?

 

[cimperia]

Yes, I get this result and notice the space in the path.

TempFolder: C:\Users\User Dell\AppData\Local\Temp\

When I check TempFolder, no log gets created there when running SDK manager or by B4A.

I suggested a fix in a post above, would it still be applicable?

 

[Erel]

It looks like a combination of two issues:
- The space in the user name.
- The file system doesn't support the old DOS style paths.

You can force B4A to use a different folder by adding an environment variable named B4A_TEMP. Set it to c:\temp and try again.

 

[cimperia]

That fixed it. SDK & AVD managers now run correctly. Thank you.

BTW, the B4A_TEMP variable is a new feature in v9.50.
