Picked up _JAVA_OPTIONS: -Xmx1024m -Xms1024m

I have increase the MaxRamForDex but it doesn't work

 

[Erel]

What is MaxRamForDex set to? Have you set it while the IDE was closed?

Did is start after you update Java?

Picked up _JAVA_OPTIONS: -Xmx1024m -Xms1024m

This line suggests that there is an environment variable that affects compilation.

What is MaxRamForDex set to?

MaxRamForDex=2048, appears this error

Have you set it while the IDE was closed?

Yes

Did is start after you update Java?

I updated several things of sdkmanager

Same issue as here? https://www.b4x.com/android/forum/t...nger-compiles-any-project.103662/#post-649871
@Erel supplies a solution in that thread

Could not reserve enough space for 2097152KB object heap

Seems like there isn't enough memory available on your PC. How much RAM is installed? Try to close other apps.

 

[angel_]

8GB

 

[DonManfred]

are you using 32bit of Java?

 

[angel_]

I think so.

With B4I I have no problems

 

[Erel]

I think that your computer ran out of available memory. You should actually decrease MaxRamForDex.

 

[Pendrush]

With 32bit java MaxRamForDex=2048 is not possible, you must use Java x64 JDK.

EDIT:
I have x64 JDK and MaxRamForDex is set to 4096.

 

[Erel]

You are correct. This is the cause of this issue here.

 

[angel_]

I have set MaxRamForDex to 4096 and JDK x64, it works perfectly

Thank you
