I just installed the new version, and I have tried several times but it always compiles me with: Optimized dexer failed. Switching to Standard dexer.



I don't know if it has something to do, but I had to install it from sdkmanager:

firebase-installations
firebase-installations-interop

and perhaps for this reason it takes longer?

Does it still always fail? Does it happen with a specific project or all your projects?

It only happens to me in a project

Yesterday I was doing tests and delete line : #AdditionalJar: com.google.firebase: firebase-core (used for Crashlytics) and compile ok
Crashlytics work fine without this line, confirmed


I don't know why I put it in at a certain time, but I have removed it and compiles it every time well

Same here, in all my projects.
I use the crashlytics too.
But it only happens in the first compilation. When I compile again, I don't see this message "dexter failed".

Note that it always compiles ok, even if the optimized dexer fails. It just means that compilation will be a bit slower.

If you are able to reproduce it with a not too large project then please upload it or send it to me.

my project is big and maybe that's what makes that error jump.

I have solved it by removing: #AdditionalJar: com.google.firebase: firebase-core and it works almost 90% of the time without error in dexter

I see that the chrashlytics continues to work without this line ... or so I think

I have this line too - in all my projects - and, like I said, the dexter don't failed in the second compilation (even with this line).
I'll test if I removing this line, I don't have problems with the crashlitycs.

All My apps have this line, and that error does not happen to me.
It only happens in a large project, I think it must be because of the size of the project.

I have this a lot with pre 10.0 versions aswell.

It sometimes seems that the dexer gets stuck and only eats a lot of memory.
if it completed with the other dexer and you compile again it's suddenly fast again.

indeed especially noticable when using firebase. all the projects without firebase compile a lot faster (less file collecting to do)

what improved things a lot is putting an exclusion on c:\Android and *\objects in my anti-virus (avast) and it's less stuck than before too.

Even I disable this line before compilation:
B4X: 
#AdditionalJar: com.google.firebase:firebase-core
I get the message "dexter fail" in the first compilation.
If I compile again, I don't see the message.

I use Kaspersky and even I disable the antivirus, I don't have any improve in the compilation process.

Hi Guys
I have been working on a project, and as long as I can remember I got the message with B4A versions up to and including v9.9.

B4X: 
Optimized dexer failed. Switching to Standard dexer.
However, whilst working on a problem relating to permissions (and check if it still occurred in v10 beta)
https://www.b4x.com/android/forum/t...ons-fusedlocationprovider.119746/#post-750935
I found with v10 Beta the error report about "the dexer failed" had simply gone.

Regards
Dave

It is a good solution, I have the ESET antivirus and I have disabled the folders:

C: \ Android \
C: \ Program Files (x86) \ Anywhere Software \
\ ProjectFolder \

this makes compilation faster, and avoids "Optimized dexer failed. Switching to Standard dexer"
