Android Question Error compiling with 3.80

[brelto85]

I've just purchased the 3.80 version of B4A and when compiling my project, get the following error:
I've windows 8.1
Parsing code. 0.46
Compiling code. 1.22
Compiling layouts code. 0.09

Optimized dexer failed. Switching to Standard dexer.

i tried to change the MaxRamForDex with "1536" value and UseOptimizedDexer with "False" but i've got the same error

[UPDATE]

!! After update the B4A i've add the Facebook SDK library and i've added the following attributes

#AdditionalRes: ..\AppConfig
#AdditionalRes: C:\Program Files (x86)\Android\fb-sdk\res
#AdditionalJar: C:\Program Files (x86)\Android\fb-sdk\bolts.jar
#AdditionalJar: C:\Program Files (x86)\Android\fb-sdk\android-support-v4.jar
#AdditionalJar: C:\Program Files (x86)\Android\fb-sdk\facebooksdk.jar

with these attributes gets the error, commented these and compiles

in detail the attribute that cause the error is this:
#AdditionalJar: C:\Program Files (x86)\Android\fb-sdk\android-support-v4.jar

Based on this line in the exception ...

java.lang.IllegalArgumentException: already added: Landroid/support/v4/print/PrintHelper$1;

... it appears that android-support-v4.jar is already included somewhere in your b4a paths which means that you have the same jar library included twice.

Try to remove this line completely:

#AdditionalJar: C:\Program Files (x86)\Android\fb-sdk\android-support-v4.jar

 

[Periklis Koutsogiannis]

If the mentioned jar is already included, you will be able to use the fb sdk wrapper fine after removing the directive in question.

Please let me know if it works.

You are most welcome!

Do not hesitate to report any findings/comments in the fb sdk wrapper thread
