Android Question Optimized dexer failed. Switching to Standard dexer.

[WAZUMBi]

I know. This problem has been posted before but I have tried all the recommended solutions with no success.

I upgraded to B4A 3.82 yesterday and now I can't compile any of my old apps.
I am trying to upgrade some to Admob 2.0 with Google Play services.

I tried changing
MaxRamForDex=1024 and
MaxRamForDex=1536 and
UseOptimizedDexer=False
Another solution was conflicting libraries.

I was able to update two apps yesterday.
I was experienceing some problems with them hanging during compile also but they eventually worked.
Now, nothing.

After hanging and I get the error message 'Process is running longer than expected. Do you want to cancel it?'
I click on 'No' and get this:

The problem happens because there is another library that included the ad sdk in the jar file. Find which library causes it. If you need this library then you can open the jar file with 7zip and remove the redundant classes.

I have the same problem

When adding jB4XEncryption: 1.00 :::
"Optimized dexer failed. Switching to Standard dexer"

Deleted libraries old :::
ByteConverter 1.10 and its modules
SMB 1.10 and its modules

Solved !!
